  • Conditions: check weather, fire closures, and land-manager alerts the week you go — mountain access changes seasonally.
  • Reservations/permits: None — pay the day pass at the desk.
  • Best time to go: Weekday mornings for a quiet all-ages soak; winter weekday evenings after ski days at Lolo Pass; the 9 PM–midnight adults-only clothing-optional sessions are the signature late window — confirm which nights apply before planning around them.
  • Clothing reality: Official: swimwear required during all family/daytime sessions; pools become adults-only 18+ and CLOTHING-OPTIONAL 9 PM–midnight on marked nights (Sun & Wed per official table; one 2026 guide also lists Fri & Sat). Customary: matches — daytime textile, late-night optional. Private property.
  • Kids: Allowed.
  • Cell service: spotty — download maps and tell someone your plan.
  • Accessibility: Developed pools with deck access; indoor pool is a short walk from parking — no documented lifts; call ahead for mobility specifics.
  • Evening rule: on designated nights 9 PM–midnight the pools are strictly 18+ and clothing-optional — families must plan daytime visits
  • Children under 5 are not permitted in the INDOOR pool (state regulation) — they use the outdoor pool
  • Facility runs 9 AM–2 AM but kitchen closes at 10 PM; pool hours differ from building hours
  • Hours are seasonal and 'subject to change without notice' — call (406) 273-2290 before driving 25+ miles
  • Day passes are first-come, first-served — no reservations needed but none held either
  • Indoor pool stays ~103–106°F year-round; outdoor pool temp swings with the season — cooler in winter
  • US-12 over Lolo Pass is a mountain highway — winter driving conditions Oct–Apr
  • Resort vs lodge: 'Lolo Hot Springs Resort' covers the pools, RV park, bar/restaurant and folf course; the lodge hotel is the building next door — separate departments and phone lines
  • Hazard: Source water surfaces at up to ~117°F — stay in the managed pools
  • Hazard: Mountain-road access on US-12 — snow/ice and elk/deer at night in shoulder seasons
  • Hazard: Remote site — nearest full services back in Lolo or Missoula

About this spring

Historic springs on the Lolo Trail corridor used by travelers since the Lewis & Clark era; resort developed 1885 — indoor and outdoor natural hot springs pools plus bar/restaurant, RV park, cabins and horseback rides, ~35 mi southwest of Missoula near the Idaho line. Fee: Day admission charged — verify current rate. Bar on premises — lively late hours.

Lolo Hot Springs anchors the westernmost settlement along US Highway 12 in Montana, on the Lolo Trail corridor. The Corps of Discovery reached the springs on September 13, 1805 — Clark found the water 'nearly boiling hot' where it issued from the rocks — and the party camped and bathed here again on June 29, 1806, using a pool Indigenous travelers had dammed with stone and mud along the creek. A French trapper named Lolo, working the area about 1810, gave the trail and the springs their name. Fred Lembke built the first resort in 1885; Paul Gerber bought it in 1903 and his family ran it for 60 years, when holiday weekends could ring the springs with 500 tents.

In 1965 University of Montana students built what is credited as the first luge run in North America here, training toward the 1968 Olympics; the resort also appears in a poker scene in the 1999 film 'A River Runs Through It.' Today it operates indoor and outdoor natural hot springs pools with a bar/restaurant and RV park.

Montana geothermal context

Montana's springs cluster around Yellowstone's northern margin and along basin-range faults in the western half of the state. A large share of named sites sit on private ranch land or have limited legal access, which is why status notes matter here. Cold winters and heavy spring runoff reshuffle riverside pools every year.

What a resort site means here

A resort spring is a commercial operation: developed pools or tubs with controlled temperatures, changing facilities, and usually day-use fees or lodging packages. Expect posted rules (swimsuits, quiet hours, age limits), staff on site, and in many cases required reservations — especially on weekends and holidays.

Best time to visit

Year-Round (Best: May – October)

Pool temperatures and access can change with weather and season. Outdoor ambient temperatures fluctuate significantly across Montana. Late spring through autumn offers the most comfortable road access.
