Clouds Rest via Happy Isles Loop

Clouds Rest Via Happy Isles Loop is a 22.7-mile loop located in Yosemite National Park. This scenic and challenging loop begins at the Happy Isles Trailhead in Yosemite Valley, one of the most popular trailheads in the park. The route follows the John Muir Trail (JMT), summits Clouds Rest, and descends via the Sunrise Lakes Trail, reconnecting with the JMT for the return. This strenuous loop, with over 7,000 feet of elevation gain, offers breathtaking views of Yosemite's iconic granite peaks, forests, and alpine lakes, making it a rewarding experience for both hikers and backpackers.

DESCRIPTION

The hike begins at the Happy Isles Trailhead, following the JMT as it gradually ascends, passing scenic Nevada Falls and continuing alongside the Merced River. You'll eventually reach the junction for Clouds Rest Trail, where significant elevation gain begins, climbing steep switchbacks through forests of lodgepole pines and open granite slopes.

The summit of Clouds Rest (9,931 feet) provides panoramic views of Half Dome, Yosemite Valley, and the Sierra Nevada mountains. Though strenuous, the 360-degree views are well worth the effort.

From the summit, the trail continues along Clouds Rest Trail until reaching the Sunrise Lakes Trail. Descending through alpine meadows, you’ll pass the serene Sunrise Lakes.

The trail then reconnects with the JMT, leading you back to the Happy Isles Trailhead, retracing your steps with a gentle downhill back to Yosemite Valley.
