4Homestead Crater

Known locally as just The Crater, Homestead Crater is the only warm scuba diving destination in continental America.

It’s a geothermal spring hidden inside limestone rock, located on Homestead Resort’s property in Utah. Although it’s a 16-meter (55-foot) dome with a hole in the top, the resort created a tunnel to gain access to the swimming hole, which includes a small deck at the end. Visitors can soak in the mineral water, swim, scuba dive, snorkel, or even join a paddleboard yoga class. Its temperature ranges from 32 to 35°C (90 to 96°F) year-round.
