Fan Falls in Rocky Mountain National Park

Fan Falls is tucked away in the high reaches of the Wild Basin of Rocky Mountain National Park. This 15.5 mile, difficult trek, leads to a long set of segmented cascades spilling out of the heights and streaming down into Thunder Lake. This garden of water, wildflowers and rock is a perfect escape for those looking for a demanding hike to a more secluded spot. Explore the entire Fan Falls hike profile below for trail map, driving directions, and more tips and details to help you enjoy this adventure in Rocky Mountain National Park.

Note: Rocky Mountain National Park now requires timed entry permits from May 27th through October 10th. See the RMNP permits page for more information.

Parking & Trailhead Information for Fan Falls

The southeast corner of Rocky Mountain National Park boasts one of the loveliest portions in the park known as the Wild Basin. The Wild Basin Trailhead is located just 15 minutes outside of Allenspark, Colorado along Highway 115. There is a ranger station at at the Wild Basin Trailhead with toilets and drinking water available.

In the winter (October-May), Hwy 115 may not be plowed to the trailhead, and hikers will need to park their vehicles at a winter parking lot for Wild Basin hikes. Be aware that hikes from the winter parking lot add on another 3 miles of hiking (one-way). There are other small parking areas, like the Finch Lake Trailhead, that may be accessible and allow hikers to park closer to the Wild Basin Trailhead. It's important to know that Hwy 115, though titled a "highway", is a maintained dirt road, which means that it can be used by 2WD vehicles. However, after heavy rains and other severe weather, its quality may degrade until it is repaired. 4WD may be needed when snow is on the ground.

The Hike: Fan Falls Trail in RMNP

The hike up to Fan Falls leads through the central area of the Wild Basin, taking hikers past three sets of cascade waterfalls, around the shore of Thunder Lake, and finally to a lonely creek dropping into a series of rocky cascades.

Beginning at the Wild Basin Trailhead, the trail passes by Copeland Falls, a set of two cascade waterfalls just 0.4 mile into the hike. For details on accessing both the lower and upper leaps of Copeland Falls, be sure to explore our full trail profile for Copeland Falls.

The trail then follows North Saint Vrain Creek, until it meets with a trail junction. The trail to the right leads past a series of backcountry campsites, and is a slightly more direct route to Thunder Lake and Fan Falls. However, the left-hand trail is not much longer and takes hikers past two more waterfalls, Calypso Cascades and Ouzel Falls. The rest of this trail profile will explain this route.

Having taken the left-hand trail, it will soon cross a hefty log bridge spanning North St. Vrain Creek. Stop here to enjoy an unnamed set of cascades. Soon the trail will meet with a second trail junction at Calypso Cascades. The right-hand trail leads hikers to the cascades, over another bridge that crosses Cony Creek at 1.8 miles, then weaves up a set of switchbacks to Ouzel Falls at 2.7 miles.

After Ouzel Falls, the trail comes to a junction with the Bluebird Lake trail at 3.7 miles. However, the way to Fan falls passes by this junction and keeps going straight/northwest. In approximately 1.5 mile from the Bluebird Trail junction, the trail makes a final split. The right leads up to the Lion Lakes and to Thunder Falls. The trail to the left leads up to Thunder Lake and Fan Falls.

At Thunder Lake, the way to Fan Falls requires some listening and attention to the landscape. Hikers should be familiar with backcountry travel and land navigation because this remaining segment requires hiking on unmarked and lesser traveled social trails. Hiking along the right/north side of the lake, the way leads into the forest. When the trees open up into a clearing, the sounds of Fan Falls become apparent. Following the sound of the waterfall and the creek, hikers can pick their way through rock, brush, and deadfall until reaching the base of Fan Falls. Bluebells and other wildflowers grow out from between the rock, painting the splash and spray of the cascades with color.

The source of Fan Falls can be accessed by hiking higher to the area above the cascades. Here, a small pond holding the meltwater from the winter's snow reflects the towering and craggy peaks that surround it.

The return hike traces the same route. However, one change can be made: Instead of taking the trail back to Ouzel Falls and Calypso Cascades, hikers can take the trail that stays to the North/left of North St. Vrain creek and passes the several backcountry campsites.

The Hike: Calypso Cascades Trail in RMNP

The hike to Calypso Cascades begins at the Wild Basin Trailhead, and at just .3 mile into the trail, passes by both the lower and upper leaps of Copeland Falls. Read our full trail profile on Copeland Falls for details on how to access both sets of cascades.

After taking in the views at Copeland Falls, the trail follows the course of North St. Vrain Creek as it flows out of the rugged high country and snowfields in this wild corner of Rocky Mountain National Park. Soon the trail will split. The right-hand trail leads through a segment of trail with 5 different backcountry camping sites and on towards Thunder and Lion lakes. These backcountry camping sites can be reserved through the RMNP Backcountry Offices. The left-hand trail leads south towards Calypso Cascades and Finch Lake Trail system.

Taking the Finch Lake Trail, hikers will cross a large log bridge spanning North St. Vrain Creek. Near the bridge, you'll discover an unnamed set of cascades. After crossing the bridge, the trail follows Cony Creek for about 0.4 mile to the site of Calypso Cascades. Calypso Cascades are reminiscent of Fern Falls: the waters of Cony Creek tumble over boulders and fallen trees in a moss-covered landscape. What makes Calypso Cascades unique are the Calypso Orchids (also known as Pink Lady Slippers) that bloom in the late-spring and early-summer along the creek.

Hikers can return to the trailhead to make this a 3.6 mile hike, or can continue on the Finch Lake trail for approximately 1 mile to the site of Ouzel Falls.

Ouzel Falls in Rocky Mountain National Park

Ouzel Falls spills over a cliffside and enormous boulders, making it arguably one of the most beautiful waterfalls in Rocky Mountain National Park. Before reaching this 40-foot falls, the trail traces the course of several creeks and leads hikers past three other cascade waterfalls. Explore the full Ouzel Falls hike profile below for trail map, driving directions, and more tips and details to help you enjoy this adventure in the Wild Basin of Rocky Mountain National Park.

Note: Rocky Mountain National Park now requires timed entry permits from May 27th through October 10th. See the RMNP permits page for more information.

However, after heavy rains and other severe weather, its quality may degrade until it is repaired. 4WD may be needed when snow is on the ground.

The Hike: Ouzel Falls Trail in RMNP

This 2.7 mile hike (one-way) begins at the Wild Basin Trailhead and passes three other cascade waterfalls before arriving at the Ouzel Falls. Copeland Falls are found just 0.4 miles into the hike. For details on locating both the lower and upper cascades, explore our full trail profile on Copeland Falls. After Copeland Falls, the trail continues following alongside North Saint Vrain Creek for about 1 mile to where it splits. The right-hand trail leads south to a log bridge crossing the creek. Near the bridge, hikers can take in the sights and sounds of another small cascade.

The trail continues south to Calypso Cascades, the third and final cascade waterfall before reaching Ouzel Falls. Here the trail splits again. The left-hand/east trail leads aback towards the Finch Lake trail and the Allenspark Trailhead. The right-hand/west trail leads towards Ouzel Falls and the Bluebird Lake Trail. Here, the trail crosses a set of two bridges, then climbs uphill through a set of switchbacks. The mountains to the north now come into view, both Mt. Meeker, Pagoda, and Longs Peak. This segment of trail between Calypso Cascades and Ouzel Falls is approximately 1 mile.

A second set of switchbacks brings hikers within earshot of the falls, and they will come into view at the bridge that crosses over Ouzel Creek. However, the best views of the falls can be gained via a social trail that is located before the bridge on the left side of the creek. This unmaintained trail leads to an area above the falls with incredible views of alpine meadows and craggy peaks. As with any social trails, please use the most worn paths and hike on durable surfaces. Be aware that the rock can become slick in this area and hikers should exercise caution when navigating above the falls.

Ouzel Falls is named after the Ouzel or Water-Dipper, the only songbird that lives a mostly aquatic life. Ouzels weave globe-shaped nests near waterfalls, lakes, and streams. They dive--even walk--underwater to catch insects and larvae.

Hikers can return the 2.7 miles back they way they came to Ouzel Falls, or can hike further to destinations such as Ouzel Lake (an additional 2.2 miles, one-way).

Moraine Park Loop Hike in Rocky Mountain National Park

The Moraine Park Loop encircles the golden meadows of Moraine Park in Rocky Mountain National Park. The morning mists rising from the Big Thompson River, and herds of grazing elk make for an enchanted landscape. In the evening, the setting sun brings shadows and light play to the valley floor. All of this is against the backdrop of the distant snowcapped peaks of the Rocky Mountains. Explore the full Moraine Park Loop hike profile below for trail map, driving directions, and all the details you need to enjoy this adventure in Rocky Mountain National Park.

Note: Rocky Mountain National Park now requires timed entry permits from May 27th through October 10th. See the RMNP permits page for more information.

G. 3.4 miles : Cub Lake Trailhead
H. 4.1 miles : Continue east through Fern Lake Road
I. 4.5 miles : To Moraine Park Road

Parking & Trailhead Information for Moraine Park Loop

The Moraine Park Loop can be accessed from several different small parking areas such as the Cub Lake Trailhead and the Fern Lake Bus Stop, but the largest parking lot in the area is found at the Moraine Park Discovery Center. It's a great place to learn about the history and habitat of the area before or after your hike. Those staying at the Moraine Park Campground in RMNP can access this loop of trails by walking down the campground road, or via some short connector trails that come off the south end of the campground. Please only use well-worn trails, and don't cut across the fields from the campground, as this causes a lot of disruption and damage to the landscape.

The Hike: Moraine Park Loop Trail in RMNP

This 5.3 mile loop begins at the Moraine Park Discovery Center and follows a clockwise route around the outer rim of Moraine Park. Though this valley is the centerpiece of Rocky Mountain National Park, drawing thousands every year to watch the bull elk bugle and battle over rights to their harem of cows, the loop hike is not very well marked. However, much of this loop hike is an oft-used route for horseback rides guided by the local YMCA camp. Segments of this loop run along the dirt and asphalt roads at the rim of the meadows. Because of this, it's recommended to 1) Be very aware of cars. While the speed limit is low, drivers are often distracted by the views and wildlife, and 2) Look for paths in the meadow alongside the road. These will be safer routes than walking the roads. 3) When walking along the roads, please walk against traffic and walk in single file along the roads.

02-Moraine-Park-Rocky-Mountain-National-Park

The hike begins at a high point, looking down upon the Park from the discovery center, and the trail can be picked up just to the east of Bear Lake road. By zooming in on the google map provided above, hikers should be able to discern a trail that runs roughly alongside the road. This is the safest option. The next segment, the South Moraine Trail, can be picked up by crossing Bear Lake Road and heading west on South Moraine Road.

The South Moraine Trail travels across the foot of the moraine for which this area is named. A moraine is a deposit left by either the side or foot of a glacier (imagine the piles of dirt left by an excavator as it cuts a path through the earth). This segment of the loop is a favorite for its views and partial shade.

After approximately 2 miles on the South Lateral Moraine Trail, hikers will encounter a junction with the Cub Lake Trail. To continue on the Moraine Park Loop, the correct direction is right/north on the Cub Lake Trail. After crossing the Big Thompson River, the stream that snakes its way through the meadows, the trail will come out at the Cub Lake Trailhead. Here, the loop continues right/east along Fern Lake road. Again, it's best to travel on any well-worn paths alongside the road when possible.

01-Moraine-Park-Rocky-Mountain-National-Park

Fern Lake Road will terminate at Moraine Park Road. Here, the loop continues right/east back to the Moraine Park Discovery Center. An alternative route that avoids walking along Moraine Park Road is to cut through the Park on an established trail back down to the southeast corner of Moraine Park. Here, hikers can cross Bear Lake Road and take the same trail they used at the beginning and return to the Moraine Park Discovery Center.

Tips & Resources for Hiking to Moraine Park Loop in Rocky Mountain National Park

  • Arrive Early for Parking: It is advisable to arrive early to avoid entry lines and to find suitable parking.
  • Wildlife: Keep your distance from the Elk. While they are very used to humans, cows may be protecting calves, and bull elk can be aggressive during certain seasons. It's always best to view wildlife at a distance in our National Parks.
  • The Fences: You'll notice fences along the route, and some gates you may pass through. These have been established because of the very high populations of elk in the park, which has in turn had a negative impact on the vegetation. These are here to help reestablish overbrowsed habitat.

Cub Lake Loop in Rocky Mountain National Park

The Cub Lake Loop Hike in Rocky Mountain National Park is a great alternative to the an out-and-back hike up to Cub Lake. Along the way, hikers will pass by Windy Gulch Cascades, travel alongside the Big Thompson River, cross over an area called The Pool, journey through wetlands, and will be surrounded by sights of a glacial-shaped landscape. Explore the full hike profile below for trail map, driving directions, and all the details you need to enjoy this adventure in Rocky Mountain National Park.

Note: Rocky Mountain National Park now requires timed entry permits from May 27th through October 10th. See the RMNP permits page for more information.

H: 6.0 miles : Cub Lake Trailhead

Parking & Trailhead Information for Cub Lake Loop

The Cub Lake Trailhead in Rocky Mountain National Park has a very small parking area where only 7 to 8 vehicles can park. Chances are, if you don't arrive early in the morning, you'll need to park just .3 mile further down the road at the Fern Lake Bus Stop parking area. If both lots are full, then your best bet is to park in the RMNP Park & Ride lot and use the shuttle service to get to the Cub Lake Trailhead. Please do not park alongside the road. This causes significant erosion and damage to roadside--and you might get a ticket.

The Hike to Cub Lake Loop in RMNP

This hike profile for the Cub Lake Loop in RMNP is hiked counter-clockwise from the Cub Lake parking area. However, it can be hiked the other direction--it's all a matter of preference. The hike can also be started at the Fern Lake Trailhead.

Beginning at the Trailhead, the first mile follows the dirt road past the Fern Lake bus stop, then through a grove of aspens to the Fern Lake trailhead. The first sight along the trail worth stopping to see are the Windy Gulch Cascades. They are about .4 mile into the Fern Lake Trail, tucked away in a gulch high above the valley. You'll hear them first, but a footbridge and water across the trail will key hikers into the location of the cascades. We've created a full hike profile on Windy Gulch Cascades, if you would like more detailed information on this hidden waterfall in Rocky Mountain National Park.

windy-gulch-cascades-rmnp-lower-cascades

The next sight along the trail is Arch Rocks, where the trail winds through a series of boulders, including two massive rocks that fell from the cliffs above into the valley many eons ago. Shortly after Arch Rocks, the sounds of the Big Thompson River, Spruce Creek, and Fern Creek will fill the air. At the confluence of these streams, a bridge crosses the area named "The Pool."

After crossing the bridge at The Pool, the trail splits. The right-hand trail makes its way up to Fern Falls and Fern Lake. The left-hand trail leads to the lake--this left-hand trail is the correct trail for completing the loop. The trail then bends south, then turns east and climbs up the South Lateral Moraine. This 1.2 mile segment from the Pool to Cub Lake is the most demanding part of the hike. The trail encounters a second trail junction with the Hollowell Park Trail which bears to the right. The trail to Hollowell Park is a beautiful detour, but leads away from Cub Lake. To stay on the Cub Lake loop, hikers will continue east on the Cub Lake Trail.

Soon after the junction, the trail descends to Cub Lake. Some of the best views of the Lake come from this segment of trail. The trail then runs along the shore of the Lake before it makes a steep descent through a strange and wild area scraped by an ancient glacier and riddled with boulders.

The final trail segment leads through forest and marshland, across bridges, and down into the western edges of Moraine Park. Here, hikers will likely see elk grazing, and hear and see an extensive variety of birds among the shrubs and aspens. Before crossing into Moraine Park, the trail will split again. The right-hand trail leading along the South Lateral Moraine. The trail back to the Cub Lake and Fern Lake Trailheads, continues North/Left for about 1/3 of a mile back to the Cub Lake Trailhead.

Tips & Resources for Hiking to Cub Lake Loop in RMNP

  • TIP: It is advisable to arrive early as parking is limited. One may opt to ride a shuttle that drops you off at the trailhead.
  • TIP: Take advantage of the free park shuttle to get to the trailhead during peak seasons.
  • Bring A Picnic Lunch: The banks along the Big Thompson River can be a great place for picnics.
  • Bug Spray: Because of the amount of water along this hike, hikers will likely encounter a fair share of mosquitos; so, bring some bug spray.

Flattop Mountain in Rocky Mountain National Park

Hiking the Flattop Mountain Trail and reaching its summit offers 360 degrees of stunning panoramas in Rocky Mountain National Park. The trail begins at the Bear Lake Trailhead and traces its way through a varied alpine landscape. The hike to Flattop Mountain also provides access to both Hallett Peak and Otis Peak. Explore the full Flattop Mountain hike profile below for trail map, driving directions, and more of the details and tips you need to enjoy this adventure in Rocky Mountain National Park.

Parking & Trailhead Information for Flattop Mountain in RMNP

The hike up Flattop Mountain in RMNP begins at the Bear Lake Trailhead (driving directions) In the event that parking at Bear Lake is full, you'll then need to park at the Park & Ride near the Bierstadt Trailhead and take the bus into the trailhead. This service runs 7am to 7PM and more information on the RMNP shuttle bus routes can be found at this link.

The Hike: Flattop Mountain in RMNP

Beginning at the Bear Lake trailhead, a paved trail will run along the eastern shore of the lake. Look for signs for the trail leading towards Flattop Mountain. This .4 mile connector trail leads through stands of quaking aspens to the first trail junction. The right-hand trail leads to the Bierstadt Moraine and Lake Bierstadt. The left-hand trail leads toward Flattop Mountain and Odessa Gorge.

After hiking .5 mile on this second trail segment, the trail will fork again. The trail to the left, leads up to Flattop Mountain and the trail to the right leads down into the Odessa Gorge area. This third and final segment is the longest, 3.2 miles. Here, the Flattop Mountain trail begins a series of switchbacks through Spruce Forest. Soon, hikers will come to the Dream Lake overlook with breathtaking views of Hallett Peak and the sheer north face of Longs Peak. Further up the trail, a second overlook reveals Emerald Lake deep in the bottom of Tyndall Gorge.

Near the Emerald Lake overlook, the trees begin to change shape, into what's called Krummholz forest. It's a German term meaning "crooked" or "twisted wood". These windswept pines look like they've been sculpted by a master bonsai artist. The trail gets a bit more steep as it climbs above treeline, running through rock and tundra, with cairns (stacked-rock markers) noting the trail where it might become difficult to discern.

At the top, it will make sense how Flattop Mountain got it's name. It's less of a peak and more of a broad field of tundra and rock. But the effort to get to the top is worth the views. Hikers can see the Mummy Range to the North as well as Lumpy Ridge. To the Southeast lay peak after jagged peak, with Longs Peak's leaden north face set against the sky.

From the top of Flattop Mountain, hikers can follow a trail through the tundra to the true peak of Hallett, which is approximately .4 mile away to the south with another approximately 400' in elevation gain. Be sure to read the tips section below for making this hike up Flattop Mountain as there are a few important aspects to this more demanding hike in Rocky Mountain National Park.

Tips & Resources for Hiking to Flattop Mountain in RMNP

  • Start early in the morning: Afternoon thunderstorms appear suddenly during the summer hiking season. For this reason, hikers are urged to start early enough to be down off the mountain by early afternoon. Many people have ignored this and been caught in really nasty, weather up on this trail. There have been weather-related fatalities here.
  • Take it Easy: It's a demanding walk up Flattop, and should not be approached as a sprint to the summit. Be sure to pace yourself and take breaks as needed.
  • Layer: It gets colder as you hike toward the top of Flattop. Be sure to have warm clothing. Hikers are also very exposed to the sunlight and risk sunburn, so be sure to wear sunscreen.
  • Food & Water: It probably goes without saying, but be sure to bring plenty of snacks and water to fuel your body for this demanding hike.
  • Trekking Poles & Traction Devices are Recommended in Spring and Winter: During this time of year, there can be patches and even longer segments of snow and ice on the trail. Because of this, we recommend Trekking Poles and/or Traction Devices for this trail.

Parking & Trailhead Information for Grace Falls in RMNP

Parking is more limited in this area of Rocky Mountain National Park, and you'll likely have to park at the Park & Ride then take the shuttle to the Fern Lake Trailhead. You'll find driving directions above to The Fern Lake Trailhead (closest to this hike), the Fern Lake Bus Stop Parking area (very limited parking), and for the Park & Ride lot. See the RMNP Shuttle page for dates and times of service. Avoid parking along Fern Lake road as this damages the road side.

The Hike: Grace Falls in RMNP

The journey up to view Grace in Falls Rocky Mountain National Park takes hikers past or near 5 different waterfalls and several other scenic sites. Refer to the sites and waypoints list below for the full set. Because the last stretch of trail from the western shore of Odessa lake to Grace Falls is unmaintained and difficult to discern, the falls are best viewed from the stretch of trail between Odessa and Lake Helene (more detailed directions are below).

Grace falls freezes over in the winter, attracting ice climbers to the area. The size of the falls and volume depends very much on the melting snowpack from Ptarmigan Glacier. The best time of year to view the falls is in the Spring-Early Summer. The area near the base of Grace Falls is prone to avalanches--especially during this time of year--which is another good reason to elect to view Grace Falls from the Fern Lake trail, rather than attempting the difficult hike and scramble to its base.

The best place to view Grace Falls is about .8 mile beyond the Odessa Lake junction where the trail begins to climb toward the top of Odessa Gorge making its way toward Lake Helene. This brings the journey to approximately the 6 mile point, or 12 miles round trip. An alternative and very scenic return route is to continue on the trail until it joins up with the Flattop Trail connector which leads east and down into the Bear Lake Trailhead. This makes for a 9.6 mile total hike. At the Bear Lake Trailhead, a shuttle system can transport hikers back to the Fern Lake bus stop. If you are considering this option, be sure to check the shuttle times and details. At the time of this writing, a shuttle transfer at the park-n-ride will be necessary to get back to the Fern Lake bus stop.

Tips & Resources for Hiking to Grace Falls Viewpoint in RMNP

  • TIP: It is advisable to arrive early at the Fern Lake Trailhead as parking is limited. If the lot is full, the best option is to use the park-n-ride shuttle that drops you off at the bus stop near the Fern Lake trailhead.
  • Begin Early: As with all longer hikes in the Colorado Mountains, it's important to start very early in the morning to avoid the thunderstorms that form in the early afternoon.
  • Trekking Poles & Traction Devices or Snowshoes are Necessary in Spring and Winter: During this time of year, there can be patches and even longer segments of snow and ice on the trail. Because of this, we recommend Trekking Poles and/or Traction Devices for this trail. Snow it thick above Fern Lake until Mid-Summer, because of this snowshoes are also recommended.

Parking & Trailhead Information for Lake Helene in RMNP

The Hike: Lake Helene in RMNP

The trail to the is located along the perimeter trail of Bear Lake, and on the northeastern end of the lake. This short .4 mile trail will connect up with the Flattop Mountain trail. After hiking .5 mile on the Flattop Mountain Trail, the trail will fork. The trail to the left, leads up to Flattop Mountain. The trail to the right leads to the lake, and then on to Odessa and Fern Lake.

It's a moderate ascent as the trail climbs approximately 2 more miles up to Odessa Gorge. At this point there is an unmaintained trail off to the left that leads hikers to Lake Helene. Because this spur trail travels over quite a bit of rock and becomes difficult to discern, the route is marked by a series of cairns (stacked rocks).

After enjoying time at the lake, hikers may want to go 1.1 mile further north on the main trail to Odessa Lake.

Fern Lake in Rocky Mountain National Park

At Odessa a spur trail takes hikers along the secluded western shore of the lake, something you can't miss if you've hiked this far. The spur is marked by a trail junction sign, and leads over a footbridge to cross Fern Creek, then through a short, narrow gorge before opening out to Odessa Lake.

Return and Alternate Route Options

Hikers have a couple options for their return route. They can turn around and hike back the way they came, or they can hike the 4.1 miles to the Bear Lake Trailhead where a shuttle system can transport them back to the Fern Lake bus stop. If you are considering this option, be sure to check the shuttle times and details. At the time of this writing, a shuttle transfer at the park-n-ride will be necessary to get back to the Fern Lake bus stop.

This route down into Bear Lake travels past Lake Helene and Two Rivers Lake. After approximately 3 miles, the trail arrives at a trail junction where signs indicate the final .9 mile trail segment down to Bear Lake and Trailhead.

This 4.1 mile route from Odessa to Bear Lake can be traveled in reverse as an alternate and very scenic option for hiking up to Odessa Lake from the Bear Lake Trailhead.

Spruce Lake in Rocky Mountain National Park

Spruce Lake is an ideal destination in Rocky Mountain National Park for those who are looking to hike through terrain with some variety. After the 3.9 mile hike to Fern Lake, the .9 mile spur trail to Spruce Lake is moderate, with a few steep and rocky segments. It's a great place to find some solitude as few hikers will push on beyond Fern Lake. Views of Castle Rock and Gabletop Mountain fill the landscape, and catch and release fishing is allowed with a valid fishing license. Explore the full Spruce Lake hike profile below for trail map, driving directions, and more of the details and tips you need to enjoy this adventure in Rocky Mountain National Park.

The Hike: Spruce Lake in RMNP

After hiking approximately 3.8 miles up toward Fern Lake from the Fern Lake Trailhead--see the full Fern Lake Trail Profile---the trail will split, just before Fern Lake, and a sign will point the way to Spruce Lake.

The trail up to Spruce Lake is a easy to moderate climb through dense woods ending with a short descent across boulder field and down into the marshland that surrounds much of Spruce Lake.

Because Fern Lake is so close to the Spruce Lake trail junction, it's worth hiking to its shores either before or after hiking to Spruce Lake.
