Lost Trail Hot Springs, Montana

Lost Trail Hot Springs is an oasis of relaxation located in the south end of Bitterroot Valley, Sula. For three decades, it has been a pitstop for vacationers, travelers, RVers, campers, and outdoor enthusiasts seeking to conquer the Continental Divide at Gibbons Pass.

Initially known as Gallogly Hot Springs, Lost Trail Hot Springs served as a resting spot for Native Americans crossing the Continental Divide.

The demanding climb rose 2000 feet in three miles and took a toll on even the fittest of men. People chose to relax at the hot springs before embarking on the arduous trek.

The springs owe their existence to James Gallogly, a forest ranger who dedicated most of his time working on the facility. After his death, the springs re-opened under a new name and management.

Today, this year-round hot spring sits at the base of Lost Trail Pass in the scenic Bitterroot Mountains. It’s an ideal soaking destination for anyone exploring Treasure State’s skiing trails.

Lost Trail Hot Springs Facilities

Lost Trail Hot Springs houses an indoor hot tub, an outdoor plunge, ten cabins, an RV park, a dry sauna, a lodge, and a motel.

The 20’ x 70’ outdoor plunge is maintained at an average temperature of 93 degrees Fahrenheit in the summer and 95 degrees in the winter. Its depth is 9 ft, but changes to 10 ft as the plunge transforms into a wading pool. Natural, mineral waters bubble up the pool at 107 degrees.

A dome covers the pool during cold months to maintain the required temperatures. The outdoor pool’s mild temperatures suit children, the elderly, and anyone affected by high temperatures.
