Frenchman's Hot Springs, also known as Frenchman's Bend Hot Springs or Warfield Hot Springs, is a hot spring located along Warm Springs Creek in the Sawtooth National Forest, 11 miles (17.7km) from Ketchum, Idaho. The springs are composed of three wide, shallow pools. The pools are rock-walled, with sand and gravel covered bottoms. The average temperature of the springs varies throughout the year, but most of the time, water enters the springs at around 124°F (51.11°C). The water in the springs is usually clear.

Insider tip — Frenchman's Hot Springs is a primitive soak along the Snake River Plain in south-central Idaho, accessible from BLM land near the Snake River. Volunteer-built rock pools capture the hot outflow against the stark sagebrush desert backdrop. The contrast between the warm soaking water and the cool desert nights is dramatic, especially in spring. A clear night sky with minimal light pollution makes stargazing an exceptional bonus here.
