One of the most unique activities you’ll ever experience in your lifetime, The Crater is a geothermal spring in a 55-foot tall, beehive-shaped limestone rock located across the street from Zermatt.
Over 10,000 years in the making, The Crater formed when water from snow melting on the Wasatch Mountains seeped deep within the earth. Two miles below the surface, the earth’s interior heated the water. As it percolated upward, it picked up minerals, which were then deposited on the surface eventually forming the volcano-shaped limestone deposit called the Zermatt Crater.
The hole at the top of the dome lets in sunlight and fresh air while the interior stays heated by the mineral water at a constant range of 90 – 96 degrees Fahrenheit.
We’ve created a tunnel through the rock wall at ground level and built decks and a soaking area for guests and the public to access the crystal-clear mineral water. You can go swimming, scuba diving, snorkeling, enjoy a therapeutic soak, or even take a paddleboard yoga class. The Crater is the only warm-water scuba diving destination in the continental US and attracts many diving enthusiasts and those wishing to get certified in a comfortable environment.
You don’t have to get wet to have a one-of-a-kind experience inside the Crater. Many guests just enjoy the self-guided Crater tour, the history, geology, and archeology of this unique natural phenomenon.
