Shoshone Lake
Last Updated: January 2026
Overview
About This Attraction
Black obsidian beaches line the north shore as Shoshone Lake spreads across the high-elevation basin. The lake sits at the headwaters of the Lewis River, surrounded by caldera-rim mountains. This is the largest backcountry lake in the contigu ous U.S. without road access, set in the Yellowstone Caldera with a max depth of 205 ft and an area of 8,050 acres.
Best Time to Visit
Early July through mid-September. Expect mosquitoes in early summer; mornings and late afternoons offer gentler light and calmer winds for crossings.
Visitor Tips
- Start early to beat mosquitoes and crowds
- Bring bear spray and a water purification method
- Use a satellite beacon; cell service is unreliable in backcountry
- Pack warm layers for cool nights and wind on the lake
