A historic geothermal lodge and open-air mineral pool in Montana's Big Hole Valley.
Jackson Hot Springs Lodge centers around a single, massive open-air concrete pool that has served as a geothermal sanctuary in the Big Hole Valley for over a century. Geothermal water bubbles from the earth at over 130 degrees Fahrenheit before traveling through pipes to feed the large outdoor soaking pool, where the temperature is maintained between 94 and 103 degrees. The pool is open to the sky, allowing visitors to float under the Montana clouds by day and the brilliant expanse of the Milky Way by night. The air here carries the honest, earthy scent of mineral-rich sulfur, rising in thick steam clouds against the crisp mountain air. Because of Montana state law, children under the age of five are not permitted in the hot spring pool, preserving a quiet, relaxed atmosphere for older soakers.
The history of these thermal waters stretches back long before the first structures were built, having been used by Indigenous peoples for generations before Captain William Clark of the Lewis and Clark expedition documented them in July 1806. Clark described the "Hot Springs Valley" in his journals, noting that the water was hot enough to cook a piece of meat in 25 minutes. Benoit O. Fournier claimed the springs in 1884, building a basic homestead and a plunge. In 1911, pipes were installed to bring the water 1,300 feet from its source, and in 1950, a rancher from Jackson Hole purchased the property. He invested 400,000 dollars to construct the expansive log inn and pool we see today, originally operating it as an exclusive retreat for travelers from the East Coast.
The main lodge building captures a classic western aesthetic, anchored by a cavernous lobby with a massive stone fireplace. Inside, the historic saloon features a large old-fashioned dance floor and walls decorated with vintage mounted trophies from Montana and Africa. The onsite restaurant, the Hot Springs Grill, serves hearty meals like burgers and local beers to hungry soakers. Overnight accommodations include straightforward, comfortable western-style rooms and cabins, many of which are equipped with fireplaces, refrigerators, and microwaves. For those who prefer a more rustic experience, tent camping is also permitted on the grounds. It is important to note that the lodge, pool, and restaurant operate on a Thursday through Sunday schedule, remaining closed to the public from Monday through Wednesday.
The lodge, restaurant, and pool are only open Thursday through Sunday, so plan your trip accordingly. Bring a warm robe for the walk between the changing rooms and the open-air concrete pool, especially during the cold winter months.
