New Providence dive sites

The Tongue of the Ocean is a deep oceanic trench that penetrates the Great Bahama Bank, reaching depths exceeding 2,000 metres. The trench creates a dramatic wall where the shallow Bahamian shelf drops vertically into deep blue water. This depth differential generates upwelling currents that bring nutrient-rich water to the surface, attracting pelagic species and supporting diverse reef life on the wall itself. The US Navy has used the trench for deep-water testing since the 1960s due to its depth and proximity to shore. For divers, the wall represents one of the most dramatic depth transitions accessible from Nassau.

The blue hole and wall sites on the Tongue of the Ocean edge are approximately 30 to 45 minutes by boat from Nassau harbour, depending on the specific site and sea conditions. Several Nassau-based dive operators run daily trips to the Tongue of the Ocean wall and nearby blue holes, typically as two-tank morning excursions. The boat ride crosses the shallow turquoise waters of the Bahama Bank before reaching the dramatic colour change where the shelf drops into the deep trench. Departures are usually around 8am with return by early afternoon.

The wall edge and blue hole sites are best suited to Advanced Open Water divers or those with equivalent experience, as the main attractions are at 20 to 40 metres and the vertical wall can be disorienting for less experienced divers. However, the shallow coral reef on the shelf top at 8 to 15 metres is excellent for Open Water certified divers and offers its own rich marine life. Many operators offer multi-level dive plans where experienced divers explore the wall while newer divers remain on the reef top under instructor supervision.
