About MOLLYS Hot Springs

MOLLYS Hot Springs offers a raw and authentic soaking experience along the South Fork Salmon River, deep within Idaho’s Boise National Forest. The spring's water reaches a steamy 138°F, inviting you to relax in its naturally heated pools surrounded by rugged forest scenery. This primitive hot spring draws those seeking a quiet connection with nature away from crowds.

Getting There

Accessing MOLLYS Hot Springs involves a short 10-minute walk from a small, limited parking area. The trail is relatively easy but unpaved, winding through a wooded area that sets the tone for your back-to-nature adventure. Signage is minimal, so prepare for a bit of navigation.

What to Expect

You’ll find hot pools fed directly by the spring’s mineral-rich, 138°F waters, forming natural basins lined with smooth river rocks. The atmosphere is peaceful and intimate, rarely visited by many, providing a serene setting among tall trees. Facilities are nonexistent, reflecting the primitive character of the hot springs in Idaho.

Tips for Visitors

Visit in any season for a warm soak, but bring sturdy shoes for the dirt trail and plenty of water to stay hydrated. Be mindful that parking spots are limited, so arrive early to secure a place. Clothing is optional here—choose what feels right for you—and pack out all trash to help preserve this natural Idaho swimming hole.
