You are here
This classic point-to-point backpacking route begins in the heart of Yosemite Valley and climbs steadily into the high country, ending at the serene Merced Lake High Sierra Camp. Covering roughly 31.4 miles round trip with significant elevation gain, the route follows a portion of the John Muir Trail (JMT) before branching off into the lesser-traveled Merced River canyon. Along the way, you’ll pass towering waterfalls, granite cliffs, and peaceful forested stretches. Though Merced Lake High Sierra Camp typically operates seasonally, the lake itself remains a stunning backpacking destination whether the camp is open or not.
Route Description
Start at Happy Isles in Yosemite Valley. Follow signs for the John Muir Trail, beginning with a steep but scenic climb past Vernal and Nevada Falls—two of Yosemite’s most iconic waterfalls.
From here, continue past Little Yosemite Valley, where the crowds thin and the forest closes in. You'll stay on the Merced Lake Trail as it branches from the JMT and hugs the north bank of the Merced River. The trail meanders through a canyon lined with pines and polished granite, passing Bunnell Cascade and Echo Valley—lovely spots for a break or a dip on a hot day.
The final stretch climbs gently into a wide, flat basin, revealing the shimmering waters of Merced Lake (~7,150') ringed by peaks and granite domes. Whether you’re camping nearby or staying at the High Sierra Camp (when open), this area offers a peaceful retreat with multiple day-hike options deeper into the Yosemite backcountry.
Flora & Fauna
This route features black oak, incense cedar, dogwood, red fir, lodgepole pine, and wildflower-filled meadows at higher elevations. Expect to see mule deer, marmots, lizards, and possibly black bears—especially near Little Yosemite Valley and Merced Lake. Keep food stored properly at all times.
MERCED LAKE HIGH SIERRA CAMP
The Merced Lake High Sierra Camp is one of the most remote of the High Sierra Camps in Yosemite National Park. Its proximity to Merced Lake makes it an ideal location for swimming, relaxing, fishing, and camping.

Permits
A wilderness permit is required for all overnight trips. Permits are in high demand, so plan ahead and apply through Yosemite’s lottery or reservation system via recreation.gov. Start at the Happy Isles trailhead and select “Happy Isles to Little Yosemite Valley” or “Happy Isles to Merced Lake via JMT” depending on availability. Bear canisters are required and can be rented in the Valley.
Considerations
-
Elevation gain is over 3,000 feet, with much of it in the first 5 miles—pace yourself and carry plenty of water.
-
The trail can be hot and exposed mid-summer; early starts are best.
-
Bugs can be heavy near Echo Valley and Merced Lake in early season—bring repellent.
-
Water is abundant along the route but should always be treated or filtered.
-
This route can be completed as a challenging day hike, but it's best enjoyed as an overnight or multi-day trip with time to explore Merced Lake or even link to nearby camps like Vogelsang or Sunrise.
