Mono Meadow to Merced Lake Loop

Mono Meadow Trailhead to Merced Lake Loop is a challenging and rewarding 71.9-mile backpacking route that forms a lollipop-shaped loop through the heart of Yosemite’s wilderness. The trail winds through lush meadows, dense forests, high alpine passes, and glacial river valleys, offering stunning views of granite peaks, cascading streams, and expansive Sierra landscapes. Best suited for experienced backpackers, this route delivers a true high-country adventure.

Begin at the Mono Meadow Trailhead off Glacier Point Road. The trail quickly drops into Mono Meadow, a lush, marshy area dotted with wildflowers and surrounded by red fir and lodgepole pine. From here, follow the Mono Meadow Trail east until it meets the Merced Pass Trail. Continue south on the Merced Pass Trail as it parallels Illilouette Creek. This stretch is forested and serene, gradually gaining elevation as you pass both Lower and Upper Merced Pass Lakes—quiet alpine tarns tucked beneath the ridgelines. At the junction, head northeast on the Red Peak Pass Trail. You’ll cross the Triple Peak Fork of the Merced River and traverse the dramatic Merced River Shelf, a stunning section with sweeping views into glacial valleys. When you reach the junction with Lewis Creek, turn left (northwest) and continue to Merced Lake, passing the Merced Lake Ranger Station and the High Sierra Camp. To form the loop, take the Merced River Valley Trail south from Merced Lake. This trail follows the river closely and offers picturesque views of granite cliffs and shady groves. Eventually, it reconnects with the Red Peak Pass Trail, from where you'll retrace your steps back past the Merced Pass Lakes and Illilouette Creek to Mono Meadow and the trailhead.
