Join us on an excursion to Ten Lakes and Grant Lakes, two clusters of crystalline backcountry lakes separated by a narrow ridge of alpine granite near the Grand Canyon of the Tuolumne River. 

The 8-mile trek to the lakes leads through picturesque high country terrain. 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 in the nearby Ten Lakes basin, stretching your legs on a day hike while learning about flora, fauna and natural history. Bring your fishing pole and California fishing license if you want to cast a line!
