Rock Key - Florida Keys National Marine Sanctuary (FKNMS) "Sanctuary Preservation Area." Spur-and-groove coral formations. Depth is 5-35 feet and snorkelers/divers of all skill levels enjoy this site. The high diversity of species makes this an excellent fish ID location.
Eastern Dry Rocks - FKNMS Sanctuary Preservation Area. Similar to Rock Key with spur-and-groove coral formations. Depth is 5-35'. Suitable for all skill levels.
Sand Key - FKNMS Sanctuary Preservation Area. One of the most popular snorkel/dive sites in the Keys. Sand Key is a small island marked by a lighthouse built in 1853. The reef is spur-and-groove with many coral fingers and gullies for exploration. Suitable for all skill levels.
Western Dry Rocks - Spur-and-groove coral formations, with high-relief coral fingers and white sand bottom. Larger animals, such as schooling tarpon, are often seen here. Depth is 5-35 feet. Farther from Key West Harbor than most of the other popular dive sites, Western Dry Rocks has been less impacted by divers and boats. Suitable for all skill levels.
Joe's Tug - A harbor tug that sank pier-side in Key West Harbor in 1986. It was raised and prepared for sinking as an artificial reef off Miami. The night before it was scheduled to be taken north, local divers surreptitiously towed the tug out of the harbor; it sank in 65 feet of water before reaching its intended resting place. Originally a classic-looking wreck, Joe's Tug was severely damaged by hurricanes in 1998, 1999 and 2005. A large moray eel makes its home under the bow and many large fish frequent the wreck. This dive requires intermediate skill levels.
Cayman Salvor - A 189 foot former Army (yes, Army!) minelayer, then a research vessel, and finally a transport for Cuban refugees during the 1979 Mariel boatlift (which resulted in her seizure by the U.S. Government.) In August 1985, while being towed to an artificial fishing reef site in deep water, she sank prematurely and now rests in 94 feet of water with her deck at 78 feet. A 200 lb Goliath Grouper (formerly called Jewfish) lives on the wreck. Intermediate divers only due to depth.
Western Sambos - FKNMS Ecological Reserve. Depth is 10-40 feet and large elkhorn coral formations are found here. Suitable for all skill levels.
Lost Reef - An interesting outer reef dive in 30-45 feet of water. Goliath Groupers are usually seen here. Suitable for all skill levels.
Trinity Cove - A deeper outer reef dive with depths to 65 feet. Due to currents, this usually is a drift dive. Excellent site to see larger animals. Intermediate divers.
Hammerhead Hill - Depending on currents, either a moored or drift dive. This site provides excellent opportunities for seeing bigger animals, including sharks, turtles, and Goliath Groupers. Intermediate divers.
