Good to know
Good to Know
- Dean's Blue Hole is genuinely one of the most famous freediving sites on Earth — multiple world records have been set here — but the destination's freediving 'scene' is essentially one site plus a small number of schools, not a broad multi-site hub.
- There are no lifeguards at Dean's Blue Hole and the drop-off from the beach is very sudden; casual swimmers and non-freedivers should stay well clear of the hole itself rather than treating it purely as a swim spot.
- Vertical Blue's own courses and the annual competition run seasonally (roughly April–November for good conditions, competition typically in May) — it's worth checking current schedules before planning a trip specifically for a course.
- If you're a complete beginner, note that some general commentary suggests Dean's Blue Hole itself is better suited to intermediate/advanced freedivers, though beginner-level courses are offered on site.
- Outside of the Vertical Blue competition period there are no lifeguards and often literally no one else at Dean's Blue Hole — bring your own buddy and don't rely on finding help on site.
- The drop-off from the shallow lagoon into the hole's 200m+ shaft is very close to shore and sudden, so casual swimmers and snorkelers should stay well clear of the edge if not freediving with proper training.
- If you want structured, supervised freediving instruction with real safety coverage rather than going it alone, book a course through the Vertical Blue Freediving School rather than freediving independently.
- The site has seen a fatality during a sanctioned competition (2013), a sober reminder that even at a famous, 'safe-looking' site, depth freediving carries real risk without proper safety-diver support.
Notable Sites
Dean's Blue Hole
- Hazards
- There is a sudden drop-off just off the beach and no lifeguards on duty, so inexperienced swimmers and unsupervised freediving attempts carry real risk; a well-known fatal freediving accident here in 2013 was widely reported.
- Location
- West of Clarence Town, on the north (Atlantic) side of Long Island, roughly 1 km from town
- Conditions
- The site is a sheltered, wind-free lagoon enclosed on three sides by a natural rock amphitheater and on the fourth by a turquoise lagoon and beach, giving calm, current-free water that is unusual for a site of this depth. The site is accessible by road with a short walk from the parking area to the beach.
- Why Notable
- Dean's Blue Hole is a blue hole in Long Island, Bahamas, with a depth of 202 metres (663 ft), making it the world's third deepest known blue hole after Taam Ja' in Mexico and Dragon Hole in the South China Sea. The hole starts at a shallow lip around 6 m before dropping vertically, and widens into a cavern roughly 100 m in diameter after about 20 m of descent. It is described as the world's third-deepest known blue hole, with a near-circular surface diameter of about 25-35 meters that widens into a roughly 100-meter-wide cavern below.
- Freediving Significance
- Due to its depth, Dean's Blue Hole is the site of a number of free diving world records, and it hosts the annual Vertical Blue freediving competition. William Trubridge broke a world record here in April 2007 reaching 84m, then 86m without fins, and in April 2010 reached 92 m without fins; Herbert Nitsch set a Free Immersion record of 120 m here in 2010; and as recently as July 2025 a Tunisian national record of 118 m was set at Vertical Blue 2025.
- Scuba Vs Freediving Note
- Not as popular for scuba diving as other famous blue holes such as Belize's or Dahab's, this site is best known specifically for freediving rather than scuba.

Overall Assessment
Long Island's freediving profile is built almost entirely around a single, world-class site — Dean's Blue Hole — rather than a broad scene of multiple named freediving locations. It is a genuine bucket-list, record-holding site and host to an elite annual competition (Vertical Blue), but the actual on-the-ground training infrastructure is modest: one internationally known dedicated freediving school (Vertical Blue) plus at least one smaller beginner-oriented outfit (Savage Diving), not a dense cluster of competing schools or dive centers.
Safety Culture And Community
- Buddy System Norms
- There is no documented site-wide enforced buddy-system policy for casual visitors — independent freedivers and snorkelers visiting outside of organized courses or competitions are effectively on their own, and several visitor reports describe arriving to find no one else at the site at all. Structured buddy/safety protocols exist mainly through organized instruction: the Vertical Blue Freediving School (associated with William Trubridge) offers lessons and courses at the hole, and instructor-led sessions bring standard freediving safety supervision (spotting, safety divers, depth limits) that a lone visitor would not otherwise have.
- Community Size And Character
- The resident freediving community is small and seasonal rather than a large, established year-round scene. Long Island as a whole has a total population of only around 3,000 people, and the freediving activity at the hole is concentrated around one or two named operators/instructors and a short annual competition window (Vertical Blue), after which the site reverts to being quiet and largely unstaffed. This is a fundamentally different character from a large, permanent year-round freediving town.
- Primary Or Secondary Identity
- Dean's Blue Hole itself is a genuine, globally recognized freediving icon on the level of Dahab or Kalymnos — not a secondary activity bolted onto a dive/surf town. It is the site of numerous world records and is described in dive-industry sources as a global freediving mecca. However, this identity is highly site-specific and seasonal: it belongs to one location (a bay near Clarence Town) on a very remote, sparsely populated Out Island, not to Long Island as a broadly built-out nomad or dive-tourism destination.
- Site Specific Note
- Multiple independent sources describe Dean's Blue Hole as a hub specifically for freediving rather than scuba, and note it is the site of the annual Vertical Blue competition, historically run by multiple-world-record holder William Trubridge.
Safety Infrastructure
- Notable Incident
- American freediver Nicholas Mevoli died at Dean's Blue Hole in November 2013 while attempting a national-record dive during a sanctioned competition, an incident that remains a reference point for the sport's safety culture at this specific site.
- During Competitions
- During the annual Vertical Blue competition, the event brings professional safety-diver coverage, judges, and medical/film crews, since it is an internationally sanctioned elite competition (recent editions have drawn roughly 20 competitors including world-record holders).
- Outside Competition Season
- Outside the competition window there is essentially no formal lifeguard or safety-diver infrastructure at the site. Tourism sources explicitly note there are no lifeguards at the blue hole and that strong swimming ability is recommended, and multiple visitor accounts describe the site as frequently unattended with no staff present at all.
