Idaho Hot Springs

Kirkham Hot Springs - Boise National Forest

Kirkham Hot Springs is located near the official Boise National Forest campground of the same name and features somewhat shallow rock pools (unimproved) with sand/rock bottoms next to the river. The multiple hot waterfalls are quite a sight! Both the pools and hot waterfalls can be seen from a large pullout off highway 21 on the west side of the campground. Be warned, this place is very popular during the summer and oftentimes winter season. Expect a full-house in the summer.

Kirkham additionally serves as an interpretive site for geothermal activity. There is a trail that winds through the seeps and sources which continuously provide the hot springs pools with fresh mineral water. There are signs along the way that describe the hot springs and area history.
