Chattanooga Hot Spring

"Located in Atlanta, Idaho, along the Middle Fork Boise River this beautiful hot spring is walled in by a man made rock wall and fed by geothermal waterfalls coming down the side of the mountain. The hot springs are not easily accessible, which also makes them less crowded. It’s recommended to visit with 4x4 or AWD as the dirt roads can be pretty difficult, especially in wetter seasons. The trail to the hot springs is steep as well. It’s not recommended to go out of your way for a visit in the spring either, as runoff can make the hot springs submerged in the river. The main hot springs pools are about 110 degrees, and there sometimes are a couple of other hot springs along the side of the river that you can explore that vary around 110 degrees. Clothing is optional at these hot springs. Camping nearby: Powerplant Campground"
