Parking & Trailhead Information for Trio 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: Trio Falls Trail in RMNP

The hike up to Trio Falls in Rocky Mountain National Park combines both distance and a fair amount of elevation gain to make this a very challenging hike. Because Trio Falls is 7 1/2 miles from the trailhead, few make the journey; but the solitude and the sights are worth it to those who make the effort. Because the round-trip hike is 15+ miles, it’s advisable to make this hike a part of a multi-day camping trip in the park. If you are considering camping, there are several reservable backcountry camping spots in the Wild Basin area, and camping permits can be obtained through the RMNP Wilderness offices.

Trio Falls is located between Lion Lake #1 and Lion Lake #2 in the Wild Basin. For a detailed trail description of the almost 7-mile hike to Lion Lake #1, which takes hikers past three other waterfalls, be sure to explore the trail profile for Lion Lake #1.

At Lion Lake #1, there is a social trail that runs along the right/east side of the lake. Because this next segment is on unmaintained trails in a remote section of the park, hikers should possess both land navigation skills, map, and equipment. This social trail leads for about 1/2 mile along the lake, beyond into rocky terrain, and eventually to the waterfall.

There are a lower and an upper set of cascades to Trio Falls. Following the trail past the lower cascades requires a scramble and negotiating an passage through thick willows and rock. Hikers should exercise extra caution in this wet and rocky terrain.
