Of all the unique and wonderful activities you can enjoy 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. The Homestead Crater is the only warm water scuba diving destination in the continental US and it attracts many diving enthusiasts and those wishing to get certified in a comfortable environment.
