About Browns Creek Hot Spring
Browns Creek Hot Spring, Idaho is a free geothermal spring along the Middle Fork Boise River Road in the Boise National Forest in Elmore County, near the remote mountain community of Atlanta. Hot water emerges at approximately 122 degrees Fahrenheit from a cliff face and cascades down in two streams. One stream flows into an old rock and mortar tub, while the other pours down as a natural hot shower into the Middle Fork Boise River. Atlanta, an isolated mountain town accessible by rough forest roads, is the nearest community.
Browns Creek is typically experienced as a natural hot shower rather than a pool soak. The water cools as it falls from the cliff, but the source temperature is high enough that care is needed. A soaking pool only forms at the base during low water conditions in late summer and fall. The spring sits alongside the Middle Fork Boise River Road, one of several thermal features along this geothermally active corridor that also includes Dutch Frank Hot Springs, Granite Creek Hot Springs, Loftus Hot Springs, and Neinmeyer Hot Springs. These are among the most scenic free hot springs Idaho offers in the central mountains.
The spring requires fording the Middle Fork Boise River, which has no bridge at this point.

Suitability & Accessibility
Who Should Visit Browns Creek Hot Spring
