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 watertemperature of 72 degrees Fahrenheit (23 degrees Celsius) all year round!


The Cave

The Cave is the newest feature and cave divers from all over Florida are now visiting Blue Grotto to explore this almost untouched beauty. What sets The Cave at Blue Grotto apart is not only that it’s a site few get to see, but the fact in remains in as close to its natural state as possible. The rock formations are fragile. Virtually every surface is covered by a deep, undisturbed layer of silt.


The Dive Experience

Only Open Water Diving Certification is necessary at Blue Grotto. It’s the safest cavern dive in the area, but it is a thrilling and fun experience for all levels of diving experience.

Instructors are very welcome to use Blue Grotto’s great training platforms in the shallower part of Blue Grotto or the training pool.

Enjoying Nature at Blue Grotto

The nature surrounding Blue Grotto is great for having a picnic with the family or friends between your dives. You can enjoy a relaxing BBQ after some great dives or even stay the night in one of our nice cabins by the pool.


The dive begins at the mouth of the cavern, which is 80ft wide and 20ft high. Look from topside into the sharp blue and you will understand why Blue Grotto is known for its exceptional visibility. 

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. But words will not do jusitice to the experience of diving in this secret underwater hideaway.

Go dive for yourself!
