Dive spot near Dahab Divers at the entrance to the reef Entrance to the reef Entrance to the Blue Hole.
There is a shallow opening around 6 m deep, known as “the saddle”, opening out to the sea, and a 26 m long tunnel, known as “the arch”, whose top is at a depth of 56 m.
The hole and the surrounding area have an abundance of coral and reef fish.
There is a local Belizean legend that the Blue Hole is cursed by the ghost of a girl who drowned herself there to escape from an arranged marriage.
Dangers The Blue Hole is dived almost every day by recreational divers.
Local dive centres take divers who are qualified to dive to 30m to do the site known as El Bells or Bells to Blue Hole.
The entry is further along from the Blue Hole at an entry called The Bells.
At 26m at the bottom of the Bells is a mini arch that should not be confused with the arch in the Blue Hole itself.
The dive is then a wall dive that finishes crossing the Blue Hole saddle at a depth of 7m.

Recreational divers do not get to see the Blue Hole arch when doing the Bells to Blue Hole dive.
The Egyptian Chamber For Diving & Watersports has a policeman stationed at the Blue Hole to ensure divers are diving with a certified guide to ensure safety procedures are followed.
However, the Blue Hole is notorious for the number of diving fatalities which have occurred in the past, earning it the sobriquet “World’s Most Dangerous Dive Site” and the nickname “Diver’s Cemetery”.
The site is signposted by a sign that says “Blue hole: Easy entry”.
Accidents happened as divers tried to find the tunnel through the reef connecting the Blue Hole and open water at about 52 m depth.
This is beyond most recreational diving limits and the effect of nitrogen narcosis is significant at this depth.
Divers who missed the tunnel sometimes continued descending, hoping to find the tunnel farther down and became increasingly narcosed; furthermore, the rate of consumption of air by an open-circuit diver increases the deeper the diver descends.
All but one of the deaths were male; a local female dive guide said that “the most dangerous substance in the Blue Hole is testosterone”, referring to a male desire to challenge risks.
The “Arch” is reportedly extremely deceptive in several ways: It is difficult to detect because of the odd angle between the arch, open water, and the hole itself.
Because of the dim lighting, most light entering from outside through the arch and lack of reference points, it appears shorter than it really is.
Belize Barrier Reef
Divers report that the Arch appears less than 10 m long but measurements have shown it is 26 m long from one end to the other.
There is frequently a current flowing inward through the arch towards the Blue Hole, increasing the time it takes to swim through.
The arch continues downward to the seabed which is beyond view and there is therefore no “reference” from below.
In the very clear Red Sea water, the arch may seem to be nearer and smaller than it is.
The diver’s mind being muddled by nitrogen narcosis.
Divers who resist the temptation of the Arch and remain within their training and limitations are in no more danger than on any other Red Sea dive site.
However, the Arch has proved irresistible for many and thus the dive site is considered unsuitable for beginners and a potential trap for even experienced divers.
Diving through the arch requires suitable training and equipment, usually including a mixed-gas qualification from a technical diving training agency, technical diving equipment such as redundant gas supply, redundant large-capacity buoyancy control device and a breathing gas with reduced nitrogen content such as trimix.
The Belize authorities claim that 40 divers have died at this site since records began; however, many local dive guides believe that the authorities are deliberately underestimating the numbers and that there have actually been at least twice that many fatalities.

6 m below the surface.
The causes of this accident are unknown, but some assume that he tried getting to the Arch.
