Parking & Trailhead Information for Lawn Lake
The hike to Lawn Lake begins at the Lawn Lake Trailhead. Several other destinations in this lesser visited section of RMNP known as the Mummy Range, can be accessed from the Lawn Lake Trailhead, including Ypsilon Lake, Ypsilon Falls, Chipmunk Lake, and the Spectacle Lakes. The parking area is located on Old Fall River Road, just north of the intersection of Old Fall River Road and Highway 34.
The Hike: Lawn Lake 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 the park has been severely damaged by floods, it’s all the more important to stay the trail.
At approximately 1.4 miles, the Lawn Lake Trail meets with the Ypsilon Lake Trail. See the full trail profiles for Ypsilon Lake and Ypsilon Falls for exploring these destinations. At the junction, the way to the Lake passes by this junction, continuing straight/North on the Lawn Lake Trail
Here, the trail comes quite close to the gorge that overlooks Roariing River. There are areas of unstable terrain and hikers should take caution and stay away from the precarious edges of the gorge.
The trail begins a demanding climb up a series of switchbacks then returns to follow river. Three backcountry camping sites are located in this stretch, just after the confluence of Roaring River and Ypsilon Creek: Ypsilon Creek, Cutbank, and Golden Banner. At 5.6 miles, the Lawn Lake Trail meets up with the Black Canyon Trail. Here, the way to the Lake is left/North, and should be clearly marked by a sign at the junction. The Lake is about 1/2 a mile further up the trail.
There is another backcountry camping site at the Lake. This site and the others along the Lawn Lake trail can be reserved through the RMNP Backcountry Offices. Greenback Cutthroat trout are plenty in the Lake, so this makes for a great fly fishing destination in Rocky Mountain National Park. A fishing license is required and State and Park fishing regulations apply.
