Fairmont Hot Springs has been a Southwest Montana destination for decades, with the resort site sitting on a virtually unlimited geothermal supply that emerges at 155 F. The property has developed across the late twentieth century into the family-resort form it has today: two Olympic-size swimming pools, two mineral soaking pools, a long enclosed water slide, full lodging, and a separate sister RV resort. The combination is unusual for a hot springs property; most operations have either a mineral soak emphasis or an aquatic-features emphasis, and Fairmont has both.
The pool inventory is built to support different user groups simultaneously. The two Olympic-size swimming pools (one indoor at roughly 86 F, one outdoor at the same temperature) are designed for swimming and family aquatic recreation, with large shallow ends for kids and deep ends roped off for lap swimmers. The two mineral soaking pools (one indoor at 104 F, one outdoor at 104 F) handle the adult soak market. The 350-foot enclosed water slide using hot springs water connects to the outdoor swim pool and operates year-round, which is unusual; most North American water slides close for winter.
The geothermal source is the operational distinction. The resort uses a virtually unlimited supply of 155 F natural hot springs water and cools it to comfortable temperatures across the pool system rather than recirculating cooled and chemically treated water. The flow-through model means the water turns over continuously, similar to Lava Hot Springs in Idaho and Bozeman Hot Springs at the other end of Montana.
Practically, Fairmont sits at I-90 Exit 211, 14 miles west of Butte and an hour and a half east of Missoula. Bozeman Yellowstone International Airport is 90 minutes east. The resort runs both year-round and serves the cross-Montana driver market, the ski-trip drive market (between Bridger Bowl, Big Sky, and Lost Trail Powder Mountain), and the local Butte and Anaconda weekend market. Lodging is on-site at the resort; the sister Fairmont RV Resort handles RV and tent camping.
