Delta Lake Trail

Delta Lake is the most sought-after off-trail destination in Grand Teton National Park, a brilliantly turquoise glacial tarn sitting at 9,007 feet directly beneath the sheer east face of the Grand Teton. The route begins at the Lupine Meadows Trailhead and follows the maintained Garnet Canyon Trail before requiring hikers to navigate a sustained off-trail scramble to reach the lake.

The approach climbs steeply through open sagebrush terrain with expanding views of the Teton Range before entering the trees and gaining elevation rapidly. The off-trail section involves boulder hopping, route-finding across talus fields, and a final push over rocky terrain to the lake shore. Navigation experience and sure-footedness are essential, as the unmarked terrain can be confusing for first-time visitors. The reward is one of the most visually striking lakes in the American West: an intense blue-green color from glacial flour suspended in the water, framed by massive granite walls rising thousands of feet on three sides. The Grand Teton itself dominates the skyline directly above, creating a jaw-dropping backdrop. Lingering snowfields often persist into late summer around the lake. The route sees significant traffic on summer weekends, and visitors should be prepared for an early start to secure trailhead parking and to enjoy the lake in relative solitude before crowds arrive mid-morning.
