San Salvador is a small, remote Bahamas island where land-based resorts and day boats reach reef plateaus, steep walls and occasional open-water shark sightings. The chief draw is the western, often lee-side dive coast, with named sites such as Runway 10, Vicky's Reef and Devil's Claw. The island also offers operator-led snorkeling, Long Bay history, beaches, mangrove habitats and slow-paced days for non-divers. Most itineraries use San Salvador Airport (ZSA), local transfers and a prearranged dive operator, rather than a liveaboard. Only Blue at Columbus Isle explicitly welcomes outside guests; Riding Rock markets separate Guanahani Divers operations. Confirm both before booking, because published service claims conflict. The Bahamas tourism board identifies the island and its dive sites, while the Bahamas National Trust protects its marine and terrestrial habitats. The easiest broad planning period is mid-November through April, though weather can disrupt boats at any time.
