Freediving in Dean's Blue Hole
A near-circular marine sinkhole in a sheltered bay west of Clarence Town on Long Island, Bahamas. At 202 metres it is one of the deepest blue holes in the world, dropping vertically from a shallow turquoise lagoon, and it is the home of the Vertical Blue freediving competition.
Why here
Dean's Blue Hole is the most famous freediving site on earth. In a quiet bay off Long Island, the seabed opens into a near-perfect circle and plunges straight down to 202 metres, one of the deepest blue holes anywhere, ringed by a shallow beach and a limestone amphitheatre. Because deep water sits a few fin-kicks from the sand, a freediver can drop along a weighted line into the blue and be back on the beach in minutes, which is exactly why it became the stage for Vertical Blue, the invitational depth competition run by world-record holder William Trubridge, where dozens of national and world records have fallen. You do not need to be a champion to dive it. The shallow rim is a calm, protected place to learn breath-hold diving, and the same warm, still, current-free water that suits record attempts suits a first freediving course. Standing on the beach watching a diver disappear down the line and rise a couple of minutes later is one of the quiet spectacles of the sport.
Best months
The blue hole is sheltered and almost current-free, with warm water year round and no boat needed, since the deep water is reachable from the beach. That makes it unusually forgiving for training and unusually suited to deep record attempts. Conditions are calmest and driest from roughly April to July, which is also when the Vertical Blue competition is typically staged. Beginners work the shallow rim and the top of the line under instruction, while depth divers use the full shaft. Long Island is quiet and small, so there are no crowds.
Getting there & around
Long Island is reached by a short flight from Nassau to Deadman's Cay, then a drive to the blue hole near Clarence Town, where a handful of small resorts and guesthouses cluster. The site itself is free to visit from the beach, so the cost is instruction, coaching and lodging rather than boats. Freediving courses and coaching book directly with the school, and the island fills around the Vertical Blue competition window, so plan lodging early if you want to watch or train then.

Vertical Blue Freediving School
SchoolVertical Blue is the freediving school at Dean's Blue Hole, founded by New Zealand world-record freediver William Trubridge, who has set world records here including unassisted constant weight without fins. The school teaches AIDA-syllabus courses from beginner to advanced in the sheltered, current-free water of the blue hole, and it stages Vertical Blue, the invitational depth competition where dozens of national and world records have been set.
