Delta Lake in Grand Teton National Park is a challenging 7.4 mile out-and-back trail with stunning alpine waters that are a milky robin's egg blue. The trail is not maintained by the park, so hikers will need to navigate over boulders and fallen trees to reach the lake. Despite its popularity, the hike offers breathtaking views of Bradley Lake and colorful wildflowers along the way. Hikers should be prepared for steep switchbacks, boulder fields, and a final climb up Glacier Gulch to reach the beautiful Delta Lake. Remember to bring plenty of water, wear sturdy hiking boots, bear spray, and be cautious on the steep terrain.

If you're looking to get away from the crowds at Delta Lake, hike another 1-2 miles to Amphitheater and Surprise Lakes.
