Delta Lake Trail

The first 0.4 mile is fairly flat. Then it climbs almost the whole way. Stay on the maintained approach toward Surprise and Amphitheater Lakes. Around 1.8 miles, keep going straight at the Valley Trail junction; after this point the shade thins and the Grand Teton starts to appear through the trees. Count the switchbacks. Pass the Garnet Canyon junction around mile 3.2, then look for the Delta Lake branch at the sixth switchback, around mile 3.4. That turn is easy to miss if you do not know to expect it. A 2026 restoration targeted wayfinding and the boulder-field line, but its finished layout is unclear; check current markers at the turn and stay on the main tread.

Beyond the branch, the path drops below the maintained trail and traverses toward Glacier Gulch Creek, with short descents and rises instead of a clean climb. It crosses the creek, then climbs the steep talus slope toward the lake. The final ascent is nearly constant, with loose stones and big boulders underfoot, before the trail levels just short of the shore. Expect the descent to take care and concentration too: one visitor reported that the downhill was harder on their knees than the uphill. Poles can help on the uneven return, but they do not make the boulder field easy. Snow and ice can linger into May and June, so early-season footing can be more serious than the mileage suggests.

The lake sits in a steep rocky basin below Grand Teton and Teton Glacier. The turquoise water and close-up peak setting are the point of the long climb. Walk toward the south side for the classic view with Grand Teton behind the lake; the creek-side shore gives a more centered look across the water and boulder slope. This is a worthwhile place to stop and take in the basin before turning around. Keep to established shore paths in this sensitive alpine setting.

Start at Lupine Meadows Trailhead at the end of Lupine Meadows Road. From Teton Park Road, turn west about one mile south of South Jenny Lake Junction and follow the gravel road for about 1.5 miles. The shared lot serves several hikes and climbs and can fill very early in summer. There is a vault toilet and bear-food storage at the trailhead; bring all the water you need for the climb and return. Dogs are prohibited on park trails.
