About Boiling Springs

Boiling Springs is a fiery hot spring tucked along the Middle Fork Payette River in Idaho. Its standout feature is a pair of natural pools nestled beneath a dramatic rock formation that steams with boiling water, reaching temperatures around 185°F. This raw, powerful spring offers an intense soaking experience unlike many other hot springs in Idaho.

Getting There

Reaching Boiling Springs requires a challenging hike of over an hour through rugged terrain, making it accessible only to those prepared for a strenuous trek. Parking spots are limited and found at the trailhead, so plan accordingly. This undeveloped spot demands a good level of fitness and navigation skills.

What to Expect

You find two intensely hot pools, enveloped by natural rock and forest sounds, with very few visitors sharing the space. The water is near boiling and requires caution when entering, offering a unique but intense soak. There are no developed facilities here—just pure, natural Idaho swimming holes in their most primal form.

Tips for Visitors

Visit during any season to avoid crowds, but always be prepared for steep terrain and variable weather. Bring plenty of water, sturdy footwear, and check trail conditions beforehand. There's no clear fee system, so practice Leave No Trace ethics and pack out all trash to keep this primitive gem pristine.
