Program Overview: Spend a long summer weekend exploring Ten Lakes and Grant Lakes, two clusters of backcountry lakes separated by a narrow ridge of alpine granite near the Grand Canyon of the Tuolumne River. The 7-mile hike to the lakes leads through picturesque high country terrain.

The trip kicks off with a Thursday evening get-together at Tuolumne Meadows Campground, where you’ll meet your naturalist guide and fellow adventurers, and review the route, Leave No Trace ethics, and safety tips, including our COVID-19 procedures.

On Friday morning, you’ll head into the Yosemite Wilderness with your guide and fellow adventurers. Enjoy stunning scenery and opportunities to explore Sierra ecology during the hike to Grant Lake, your home for the next two nights. Spend your layover day (Saturday) in the nearby Ten Lakes basin, stretching your legs on a day hike while learning about plants, animals, geology and history. Bring your fishing pole and California fishing license if you want to cast a line! On Sunday, enjoy a leisurely hike back to the trailhead.
