In the deserts of western Utah, there are secrets beyond imagination.

Bonneville Seabase is one of those secrets. Located 40 miles west of Salt Lake City on the outskirts of Granstville, there is a natural phenomenon where spring water rising through the ancient lake bed of Bonneville becomes almost 3% saltwater. At the salinity of the ocean, the water wells up as warm springs, and with the addition of ocean fish, an inland ocean was formed for SCUBA and snorkeling.

During this pandemic, Scuba divers and snorkelers and campers are welcome to come and explore the depths. We space your entry times to give all of us personal space, therefore we absolutely need reservations. And if your plans change, it is very difficult when we don’t know that you aren’t coming as planned..

Diving and snorkeling is still safe, and with a little patience, you will see what lies beneath the surface of our little inland sea.
