This dive site, 40 Fathoms Grotto, located 15 minutes outside Ocala, Florida, has been operated by the Commercial Diving Academy since 2006. Primarily a commercial dive training facility, it features various artificial attractions such as boats, motorcycles, a mini-sub, and platforms scattered across its underwater landscape. While technically open to recreational divers due to contractual obligations, a prohibitive $200 entry fee has been established to deter casual visitors.
The dive site does not mention specific marine animals or plant life. As a commercial training facility with dark, green water and numerous artificial structures, it is not primarily known for its biodiversity. Any aquatic life present would likely be limited to common freshwater species adapted to low light conditions.
Due to its primary function as a training site, 40 Fathoms Grotto is likely accessible year-round for commercial operations. Recreational divers, if they choose to pay the high fee, should be prepared for dark, green water with variable visibility (3-12m) and focus on exploring the numerous submerged objects. It is not suitable for snorkeling or freediving given its depth, conditions, and purpose.
