Phelps Lake jumping rock

Confirmed by 0 jumpers
The best-known jump in the Tetons: a granite shelf about 20 feet above deep, clear water on the east shore of Phelps Lake, reached by an easy walk from the Laurance S. Rockefeller Preserve. The water is snowmelt and stays cold all summer, and there is usually a line of people talking themselves into it.

Warnings
Bad falls here have put people in the hands of park rescue — commit and jump out from the rock rather than stepping off it. Depth is not posted; check your landing. Alpine water will knock the wind out of you, and it is a 2-mile walk back to the car. Active bear country: carry spray and make noise.
Access
Grand Teton National Park entrance fee applies. From the Laurance S. Rockefeller Preserve trailhead it is about 2.3 miles to the rock along the east shore; Death Canyon trailhead is a similar distance with more climbing. The preserve lot holds about 50 cars and is the hardest parking in the park — get there at or before sunrise in July and August. The pin marks the east-shore rock area; follow the shoreline trail and listen for people.
Best conditions
July through early September. Mornings for parking, afternoons for warmth.
