Only Blue Diving is a PADI dive center based at Club Med Columbus Isle on San Salvador Island, The Bahamas. The center sits on an open lagoon overlooking a coral plateau that drops into a vertical wall reaching about 35 meters, with caverns, faults, chimneys and tunnels beyond. Boat dives run along the sheltered western side of the island, combining reef dives with drift dives. Guests can book 1 to 3 dives a day with flexible multi-day packages, choose guided or unguided diving, and rent premium Scubapro gear; a private dive boat is available on request. Divers returning after a break receive a free refresher when they book two or more dives. The center runs the full range of PADI training from entry-level courses through Advanced Open Water, Rescue Diver, Deep Diver and specialty courses, plus IANTD and PADI technical diving programs and Project AWARE conservation courses covering coral reef restoration and shark protection. San Salvador's walls and channels are known for encounters with reef sharks, hammerheads and other pelagics, and the team is regularly praised by guests for its safety-focused, well-organized boat operations, multilingual staff and warm atmosphere.
