About these waters
A National Register-listed historic inn on nearly 300 acres between Butte and Helena, run as a wellness retreat with an alcohol-, drug-, and smoke-free ethos. Soakers use a co-ed outdoor pool, gender-separated indoor plunges near 108°F, steam rooms, saunas, and a cold plunge, plus massage services. Day passes admit non-guests, while themed inn rooms and group retreat spaces cover overnight stays. Expect rustic character rather than polished resort gloss.
