Lolo Hot Springs Pools Resort, Lolo, Montana

Lolo Hot Springs Pools Resort sits at 38500 U.S. Highway 12 in Lolo, Montana, in Lolo National Forest between the Bitterroot Valley town of Lolo and the Idaho line at Lolo Pass. The resort operates separately from the Lodge at Lolo Hot Springs hotel next door: this listing covers the pools, RV park, bar and restaurant, and disc-golf course. Two mineral pools serve day and overnight guests — an indoor hot pool the operator lists around 103–106°F by season and an outdoor pool that runs cooler (roughly mid-70s to mid-80s°F depending on weather). Lewis and Clark’s journals record the Corps of Discovery bathing here in September 1805 and again in June 1806 after crossing Lolo Pass. Today the property adds horseback rides, snowmobile rentals in season, a gift shop, and camping across the road from the pools. The operator notes the resort is in bear country. Day soak passes are first-come rather than reserved, which is uncommon among developed Montana resorts that require advance tickets.
