Chattanooga Hot Springs

Chattanooga Hot Springs is a primitive hot spring at the Middle Fork of the Boise River

Chattanooga Hot Springs is one of many hot springs along the Middle Fork of the Boise River located 1.5 miles away from the historic mining town of Atlanta. This remote destination, surrounded by the mighty trees of Boise National Forest, offers a great soaking experience in nature with a spectacular view of the Sawtooth Wilderness.

The hot spring features a large pool built by volunteers at the foot of a cliff. The hot water comes out of the geothermal cliff at a temperature of 120° F. Then it runs 100 feet down to the rock-and-sand bottom pool, cooling down to 100-110° F or above depending on the season. It is open all year long.

The steep cliff path runs 100 feet down to the pool. The pool becomes visible from the upper part of the trail.

Clothing is optional at the hot spring. This is a remote location with no services available. Power Plant Recreation Area and Atlanta Hot Springs are located nearby.

Besides hot springs bathing, the Atlanta area offers a wide range of outdoor activities including, hiking, swimming, mountain biking, fishing, nature viewing, snowmobiling, and much more.
