Crystal Hot Springs

Crystal Hot Springs in Honeyville has been open since 1901, back when it was Madsen Hot Springs, and its odd party trick is a 120 to 134 F hot spring rising less than 50 feet from a cold one. Today you get a soaker and cave pool, three hot tubs, a lap pool and a slide pool, with temperatures posted by staff every hour. Adult entry is $18, plus $2 for the waterslide. The pools open afternoons and evenings year-round, but closed on Halloween, Thanksgiving and Christmas and whenever there's lightning. Camping is no longer offered, so book a bed elsewhere.
