In the 1930s, the Jenny Lake Ranger Station and Museum opened as the park’s first visitor facility. Today, climbing rangers provide safety information, issue backcountry and boat permits, share climbing route conditions, and perform mountain rescues. Climbing and day hiking do not require a backcountry camping permit unless camping overnight in the backcountry. Backcountry permits involving climbing or mountaineering, and camping in Garnet Canyon must be obtained at the Jenny Lake Ranger Station.
