Program Overview: Spend a long summer weekend exploring Ten Lakes and Grant Lakes, two clusters of backcountry lakes 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, where you’ll meet your naturalist guide and fellow LGBTQI+ adventurers, and review the route, Leave No Trace ethics, and safety tips.

On Friday, 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. Set up a base camp by Grant Lake, your home for the next two nights. Spend your layover day 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 beautiful hike back to the trailhead.
