The Cavern

Dive 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 Blue Grotto Cave is our 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 as Blue Grotto is 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.

Unbelievable visibility!

"Actually the visibility is so good, that you can lie on the botton and bird-watch if you like!"
