Blue Grotto is the largest clear water cavern located in the heart of freshwater spring country in Williston, Florida. The Blue Grotto lets you dive down to a depth of 100 feet (30 meters) in crystal clear water all the way down at a water temperature of 72 degrees Fahrenheit (23 degrees Celsius) all year round.
The dive begins at the mouth of the cavern, which is 80ft wide and 20ft high. Look from topside into the sharp blue of the pool and you will understand why Blue Grotto is well known for its exceptional visibility year round. 30ft below the surface is the only air bell available to spring divers in the region, filled with fresh compressed air that allows you a unique opportunity to stop and talk with your buddy under the water. Descending from there, at 50ft a permanent guideline brings you to the crescent shaped cavern where you will experience an array of fossils along the walls of the camber and an abundance of aquatic life waiting for a free handout.
The Blue Grotto Dive Resort offers a fully equipped dive shop and shelters for your diving gear. Shelters can be reserved via email or phone. There is also a bathhouse with hot showers.
