The certification required depends on which blue holes you want to explore. Several oceanic blue holes can be dived at recreational depths by Advanced Open Water certified divers, entering the mouth and descending along the walls without penetrating overhead environments. Inland blue holes with cave passages require full cave diving certification, and many of the deeper oceanic blue holes demand technical diving qualifications with decompression capability. The most popular recreational option is the oceanic blue holes along the barrier reef, where divers can descend the open vertical shaft to around thirty metres and observe the dramatic colour changes and geological formations.

While Belize's Great Blue Hole is a single large collapsed cave system visible from space, Andros contains over two hundred individual blue holes of varying sizes and types. The Andros blue holes include both inland freshwater cenote-like formations connected to underground cave systems, and oceanic blue holes embedded in the reef platform that experience tidal current exchanges. Many Andros blue holes have never been fully explored. The diversity is the key distinction: some are vertical shafts, others horizontal cave networks, and some feature remarkable hydrogen sulphide layers and fossilised remnants.

Andros Island is accessible by short flights from Nassau on small aircraft, with services to Andros Town, Congo Town, and San Andros airports. The flight takes approximately fifteen minutes. Alternatively, a government ferry operates from Nassau to Fresh Creek on a regular schedule. The island has limited tourism infrastructure compared to Nassau or the Exumas, with a handful of dive lodges and small hotels. This remoteness is part of the appeal, as dive sites are uncrowded and the blue holes are often dived with no other groups present. Advance booking with a local dive operator is essential.

The tidal current through Current Cut reaches 6 to 10 knots, making it one of the fastest drift dives in the Caribbean. The narrow 100-yard channel between Eleuthera and Current Island funnels the tide, creating incredible speed. The entire drift lasts roughly 10 minutes.

Advanced Open Water certification is the minimum, but significant drift diving experience is strongly recommended. This is not a casual dive -- the current is extremely powerful and there is no option to stop or turn back once committed. Contact a local dive operator on Eleuthera for guidance before attempting this dive.
