Conch Reef offers diverse underwater terrain, transitioning from shallow reef structures to a wall that descends to 40 metres. Located 9000 metres from shore, this site requires boat access and is suited for intermediate divers due to moderate, unpredictable currents. Visibility typically ranges from 10 to 30 metres, allowing for clear observation of the topography. Water temperatures remain between 24C and 28C. Divers should be aware of boat traffic, entanglement risks near artificial reef structures, and sharp coral. A drift plan is recommended, and divers must deploy an SMB during ascent. The average depth is 15 metres, with typical dive times around 30 minutes.

Pickles Reef is a combination of natural hard and soft coral formations and artificial reef structures located within the Molasses Reef Area. The site features depths ranging from 6 to 30 metres, with an average depth of 15 metres. Divers experience mild currents and visibility typically between 15 and 60 metres. Access is by boat only, situated approximately 8500 metres from shore. The site is suitable for beginners, though caution is required regarding sharp coral and rocky structures. Maintaining neutral buoyancy is essential to avoid contact with the seabed. Water temperatures remain between 24 and 28 degrees Celsius throughout the year.

Davis Reef is a marine site located 7242 metres from shore near Islamorada. The reef structure ranges from 5 to 18 metres in depth, with an average of 7 metres, making it suitable for intermediate divers. Access is by boat only, and the site supports night diving. Visibility typically fluctuates between 10 and 30 metres, with mild currents present. Divers should be aware of boat traffic, jellyfish, and sharp coral. Species recorded around this area include barracuda, nurse sharks, angelfish, moray eels, and various wrasses. Please note that recent high water temperatures have caused widespread coral bleaching and mortality in the Florida Keys, which may impact current reef health.

The USCG Bibb is a decommissioned US Coast Guard cutter resting upright on a sand bottom. The main deck sits at approximately 29 metres, with the keel reaching 40 metres. This site is strictly for advanced divers due to the depth and the strong currents that frequently affect the area. Boat access is required, and divers should use a surface marker buoy. Visibility typically ranges from 10 to 30 metres. Divers must manage buoyancy carefully and remain aware of entanglement risks within the wreck structure. Current strength and direction shift with the tide, necessitating careful planning for descent and ascent.

Barrier Reef Deep at Davis Reef features a distinct wall and drop-off topography. The site ranges from 18 to 27 metres in depth, with an average of 23 metres. Access is exclusively by boat, as the site is located 5000 metres from shore. Divers should be prepared for moderate currents and potential boat traffic in the area. Due to the depth and current, this site is suited for intermediate divers. Visibility typically fluctuates between 12 and 30 metres. Divers should exercise caution regarding sharp coral and the presence of sharks in the marine environment.

The USCG Duane is a 99-metre decommissioned Coast Guard cutter resting upright on a sandy bottom at 36 metres. The wreck's superstructure rises to approximately 18 metres, allowing the full profile to be visible in typical conditions. This site is intended for advanced divers due to significant depths, strong currents, and potential entanglement hazards within the overhead environment. Visibility ranges from 21 to 36 metres. Access is by boat only, and divers should use the mooring line for descent. The site features a range of facilities including air fills, rinse stations, and guided tours provided by local dive shops.

Fire Coral Cave is a shallow reef and cave system located 5000 metres offshore. Divers navigate depths between 5 and 9 metres, with an average depth of 8 metres. The site features an overhead environment that requires precise buoyancy control to avoid contact with sharp coral structures. Visibility typically ranges from 12 to 30 metres, though moderate currents are common. Access is exclusively by boat, and guided tours are recommended for those unfamiliar with the cave layout. Due to the presence of fire coral within the tight passages, protective gear such as a full wetsuit or dive skin is advised for all divers.
