About this swimming hole

A backcountry lake in Grand Teton's Laurance S. Rockefeller Preserve, reached by trail from the LSR Preserve Center. The lake's famous Jumping Rock rises about 18–20 feet over deep, crystal-clear water, and visitors jump — never dive — from it. Like all Teton lakes the water is cold, but it is refreshing on a hot day; arrive early because trailhead parking is limited.
