This dive site, The Blue Grotto, is renowned as the largest clear water cavern in Florida's freshwater spring country, located in Williston. It serves as an extremely popular training ground for divers due to its consistent conditions and unique underwater environment. Divers navigate a large, open cavern, descending into crystal clear waters with prominent rock formations, making it an excellent location for skill development and cavern exploration.
The Blue Grotto is home to typical Florida spring aquatic life. Divers can expect to encounter various fish species such as bluegill, bass, cichlids, catfish, and tilapia. There is also a good possibility of sighting turtles gracefully navigating the cavern environment.
With a consistent water temperature of 72 degrees F (approximately 22 degrees C) all year round, The Blue Grotto can be visited comfortably in any season. It is highly recommended for beginner divers seeking a safe and controlled environment for training, as well as for experienced divers looking to refine cavern diving skills or enjoy a serene freshwater dive. Its suitability for both snorkeling and freediving makes it a versatile destination for all water enthusiasts.
