“Of all the unique and wonderful activities you'll be part of at the Homestead, there is nothing quite like the Homestead Crater. It is a 55-foot tall, beehive-shaped limestone rock that nature has hollowed out and filled with 90° to 96° water. We have created a tunnel through the rock wall at ground level and built decks and a soaking area for our guests and the public to access the crystal clear mineral water. You can go swimming, scuba diving, snorkeling or enjoy a therapeutic soak.”Source: The Homestead Website at http://www.homesteadresort.com/leisure/crater.html

“SCUBA DIVING and SNORKELINGBonneville Seabase is your inland source for warm water SCUBA diving and snorkeling with tropical salt-water fish. This geothermally heated, salt water, high altitude mini “ocean” is the only one of its kind for SCUBA diving, snorkeling, and training. Whether you are feeding the beautiful French Angel fish or observing the docile Nurse Sharks, you’ll never believe you are the middle of Utah.”
