Kirkham Hot Springs

Getting There

Located along Idaho Highway 21, approximately 30 miles northeast of Lowman. Park at the Kirkham Campground trailhead and walk a short distance to the springs. The road is paved but winding; allow extra time in winter when ice can be a hazard. Roughly 90 minutes from Boise.

When to Visit

Late summer and early fall (August through October) offer the best conditions: the river is lower, exposing more soaking pools at comfortable temperatures. Spring runoff floods many of the pools. Winter access is possible but the highway can be icy and the campground is closed.

Fees & Permits

Free for day use. Camping at Kirkham Campground costs approximately $20 per site (first-come, first-served). No reservations. Pack out all trash; the area is heavily used and overflow trash damages the experience for everyone.

Safety & Etiquette

Source water emerges scalding hot, well above 150°F. Only the river-blended pools at the bottom are safe to enter. Test water temperature with your hand before stepping in. Keep children close and supervised; cliff edges and slippery rocks are real hazards. The river itself runs cold and swift, so never swim it during high water.

Nearby

Other Idaho 21 hot springs include Bonneville Hot Springs (8 miles east, also USFS) and Sacajawea Hot Springs (15 miles east). The Stanley Basin and Sawtooth Mountains are an hour further northeast with abundant hiking and additional springs.
