The hike begins at the Lawn Lake trailhead. Over the course of the next couple miles we'll catch sporadic views of Deer Mountain, Longs Peak, and other peaks surrounding Horseshoe Park and Endovalley areas. At just over a mile view the steep banks of Roaring River, and witness the destruction of the Lawn Lake flood.  At roughly 1.4 miles  arrive at the Ypsilon Lake junction. At just over 3.5 miles the trail finally flattens out and descend a short distance to Chipmunk Lake. From its shore enjoy views of Ypsilon Mountain. After passing Chipmunk Lake the trail descends about 4.5 miles to Ypsilon Lake. Ypsilon Lake sits at the base of Ypsilon and Chiquita Mountains.
