Trail guide
Lone Pine Lake Trail is an out-and-back from East Inlet Trailhead to Lone Pine Lake on the park’s west side. The mapped corridor is 5.4 miles each way, or 10.8 miles round trip, with about 1,500 feet of climbing. Allow around six hours; a slower pace or a long lake stop can push it toward seven. The route starts near 8,400 feet and reaches nearly 9,900, so the altitude and late climb make this a hard day. Published figures range from about 10.6 to 11 miles round trip; this one follows the mapped trail to the lake and back.
The route starts at East Inlet Trailhead, at the end of West Portal Road. East Inlet Trail continues about 1.5 miles past Lone Pine Lake toward Lake Verna, but that is a longer hike. The distance here ends at Lone Pine Lake. Pets are prohibited on all Rocky Mountain National Park trails. Snow and ice can linger on high trails into summer.
About a third of a mile from the trailhead, a short optional spur reaches Adams Falls. The water drops in several steps through a narrow rock gorge. The lower overlook faces the falls; from above, the view opens toward Grand Lake. This is a worthwhile early stop, but the falls spur is not included in the mapped 10.8-mile lake route.
The trail reaches East Meadow at about 0.6 mile and follows its north edge beside East Inlet Creek. Mounts Cairns, Craig, and Wescott rise around the open valley. A low bluff near 1.4 miles gives a wider look over the meadow and creek before the route turns into a more sustained climb.
Past the meadow, the tread gets rockier as it climbs the lower slopes of Mount Cairns. Gaps in the trees look west toward Grand Lake, and smaller falls and cascades appear higher along East Inlet. The trail crosses East Inlet Creek before the lake. Expect the upper half to take more effort than the first, gentler stretch.
The lake sits below steep granite slopes. A broad granite slab near its southwest end makes a good place to stop, with Peak 12,260 and Andrews Peak rising across the water. For a photo, include the lake in front of those peaks; the granite shore gives the frame a clear foreground.
East Inlet Trail is listed on the National Register of Historic Places for its historic naturalistic trail design. The register record identifies significant work in 1934 and 1945, so the route’s place in the park’s early trail history is part of the walk.
