The Crater is the only warm-water scuba diving destination in the continental United States, and one of the most singular natural features in the Wasatch. The dome formed over thousands of years as mineral-rich water rose from deep underground and cooled at the surface, building stone, layer by layer, until it sealed itself.
Inside, the water is glass-clear. Daylight enters through an oculus at the top of the dome and falls in a single shaft to the pool below — a quiet, almost sacred light that no photograph quite captures.
Some places are built. This one was waiting.
Two ways in.

A one-hour soak in 96°F mineral water — naturally rich in calcium, magnesium, and trace minerals. $30 per session. Weekdays 10:30am–9:30pm. Weekends 9:30am–9:30pm.
Scuba Diving
Year-round warm-water diving inside a geothermal dome — a bucket-list experience for certified divers and learners alike. Weekdays 12:00pm–8:00pm. Weekends 10:00am–8:00pm.
