After you’ve been soaked by the casinos, head less than an hour out of Las Vegas to the warm, welcoming oasis known as Goldstrike Canyon Hot Springs. You’ll have to in around giant boulders but it’s worth the trip. The water here is between 70°F (21°C) to 144°F (62°C.)
This resort in Fairbanks is well-known for the northern lights, the Après Ski scene, and its nigh-legendary healing mineral waters. The water here is 45°F (7°C). As a rule, the temperature is lower in the center and a bit higher close to the rocks. Visit in the winter and ice flakes form in your hair while you’re soaking.
