Parking & Trailhead Information for Ypsilon Falls
The Hike: Ypsilon Falls Trail in RMNP
The hike begins on a 1.4 mile stretch of the Lawn Lake trail before the intersection with the Ypsilon Lake Trail. This initial segment climbs a series of switchbacks. While it may be tempting to cut the switchbacks, they are there for a couple important purposes: to control erosion, and to preserve your energy. Because this area of RMNP has been severely damaged by floods, it’s all the more important to stay the trail. Because of the floods, there are also areas of unstable terrain.
At 1.4 mile, the Ypsilon Lake trail junction will emerge on the left-hand side of the Lawn Lake trail. Here, the trail crosses the Roaring River–but the bridge has been washed out by a flood in the Spring of 2013. At the time of writing this trail profile (June 2016) the bridge has not been replace. However, the river can be crossed at low water. It’s easy to underestimate the hydraulic force of a river, so exercise care in crossing. If you’re planning to hike to Ypsilon Lake, it’s important to have a back plan, just in case you run into high water levels at the ford. Typically, the water levels are low, but both snowmelt and heavy rains can change levels quickly.
Approximately 0.5 mile after crossing the Roaring River (@ 2 miles), the trail begins a sustained climb along the ridge of a moraine. This longest segment of the hike leads through thick timber, then crests at 3.8 miles before descending to Chipmunk Lake @ 4.0 miles. The mountain peak reflections in Chipmunk Lake make this worth stopping for a photo.
There is a backcountry camping area with two individual sites just past Chimpmunk Lake at 10,640′. Camping permits can be obtained through the RMNP Wilderness offices. The trail from Chipmunk Lake to Ypsilon lake is just 0.5 mile, arriving at Ypsilon’s western shore. Hikers who pause to listen may hear the sounds of Ypsilon Falls. This segmented and tiered cascade can be accessed by crossing a small footbridge, then hiking toward the sounds of the falls along Ypsilon’s northwestern shore.
The return hike follows the same route back to the Lawn Lake trailhead, making this a 9-mile, round-trip journey.
