Lolo Hot Springs
Lolo · Lolo Creek, US 12 below Lolo Pass (Lolo National Forest area)
The Lewis and Clark party came through here on September 13, 1805, and there's been a resort since 1885, on US 12 below Lolo Pass. The indoor pool runs 104-106 degrees in summer, and the larger outdoor pool that runs 78-85 in summer and cools to 74-78 in winter, so in January the real soak is indoors. Day passes are first-come, first-served, with adults at $16 and under-5s free. It's open until midnight on Sunday, Wednesday, Friday and Saturday and until 10pm otherwise. Camp across the road, or book a deluxe cabin, which comes with two day passes.
