The 40 Fathom Grotto is a premier Commercial Diving Academy located in Ocala, Florida. This stunningly beautiful, natural sinkhole is the only place in the eastern United States where you can dive over 200 feet below the water’s surface while still remaining in open water. The significant depth and breadth of this feature has made it world famous as one of the best dive training centers on the planet.
The underground river that feeds the grotto provides a constant supply of clean, clear water, perfect for diving. Water in the grotto is about 72 degrees Fahrenheit at the surface and 68 degrees at depth. The sheltered nature of the grotto means that waters are largely unaffected by wind, waves, tides, or currents and therefore allow for perfect diving conditions year-round. Furthermore, man made structures, such as docks and walkways, enhance the grotto and allow for comfortable access into the sinkhole.
Special bubbler vents aerate the water at the dive site to clear away duckweed and other surface debris. Once submerged, descend through this freshwater paradise to explore Pleistocene-era marine fossils over 30 million years old, present in the limestone walls of the grotto. Once you reach the bottom of the sinkhole, you will encounter fun artifacts like antique cars, an abandoned airplane, and sunken boat wrecks.
The 40 Fathom Grotto works with both experienced, certified divers and guides but also offers dive training programs for new divers. The training can be completed in as little as two days at the grotto provided you complete online training in advance of your visit to the grotto.
40 Fathom Grotto provides a full-service experience and has parking, changing and restroom facilities on-site. Additionally, a dive store provides state-of-the-art dive equipment for purchase. Tank refills are available and include Air, Nitrox, Oxygen, Helium, Trimix, and custom blends.
