Gilbert Lake Access is located at the Onion Valley trailhead, 15 miles east of Independence off Highway 395, offering ample parking, vault toilets, information kiosks, and bear boxes.

The 2-mile hike with a 1,200-foot elevation gain to Gilbert Lake at 10,400 feet makes it an accessible day trip for hikers, with nearby camping available at Onion Valley Campground and additional Forest Service campgrounds in the area.
