Atlanta Hot Springs is a beautiful oasis in a remote area of Central Idaho, located on the slopes of the Sawtooth Mountains within the Boise National Forest. The historic mining town of Atlanta lies just a few miles away.

The hot springs are accessible year-round, but because the area sits deep in the forest at a higher elevation, the best time to visit is from late June through September.

The main access road via Middle Fork Boise Road is not plowed in winter and is usually closed or impassable from November through May due to deep snow, ice, and avalanche danger. Once snow sets in (typically by late October), Atlanta is reachable only by snowmobile, snowcat, or on skis/snowshoes — a route suitable for experienced backcountry travelers.

👉Know Before You Go:

There are no gas stations nearby, so fill up before heading into the area
Cell reception is spotty around Atlanta
Emergency services are not available.

Atlanta Hot Springs Geothermal Experience

Hot geothermal water emerges at about 145°F (63°C) and is diverted through two pipes into a volunteer-built, six-by-twelve-foot rock-and-masonry pool. As the water flows into the pool, it cools to around 110–97°F (43–37°C) depending on the weather. The pool can be drained and refilled, and temperature control is available.

Water from the pool flows into a large warm pond known as “Frog Pond,” popular for summer swimming and family fun.

Swimsuits are not mandatory but are recommended, as the site is visible from the road.

⚠️ Note: Red Spider Mites have been reported. If you want to take a bath in the hot springs, see information on dealing with red spider mites.

Nearby sites include Power Plant Recreation Area and Chattanooga Hot Springs.

Beyond soaking, the Atlanta area offers plenty of outdoor adventures surrounded by rugged peaks, clear rivers, and alpine forests.

You can explore the old mining town of Atlanta with its historic cabins, mining relics, and 1860s schoolhouse.

Trails like Buck Creek, Graylock Mountain, and Powerplant lead through pine forests and along the Middle Fork of the Boise River, offering quiet, scenic views. The river and nearby creeks provide great trout and whitefish fishing, while wildlife such as elk, deer, and eagles can often be seen in the hills.

Mountain bikers and photographers will find endless inspiration in the dramatic Sawtooth landscape, and in winter, snowmobiling and cross-country skiing offer peaceful ways to enjoy the snowy backcountry.

Camping near Atlanta Hot Springs is available at Power Plant and Riverside Campgrounds, both in the Boise National Forest. Neither campground has running water or electrical hookups, so visitors should bring their own supplies.

Power Plant has forested sites with picnic tables, fire rings, and river access, suitable for tents or small RVs. Typically open from May through September and operate on a first-come, first-served basis.

Riverside Campground sits right along the Middle Fork of the Boise River and offers scenic views, picnic tables, fire pits, and fishing access. Reservations can be made through Recreation.gov during the open season from mid-June to the end of September; otherwise, sites are first-come, first-served.

Additional lodging can be found in Lowman or Idaho City, about 30 miles away.
