The chimney entry to the Blue Hole traverse - a straightforward recreational dive attached to the most lethal dive site in recreational diving.
The Bells is a narrow chimney cut into the reef wall a short walk north of the Blue Hole, on the coast a few kilometres north of Dahab. You giant-stride in from the shore, drop through the crack, and exit at roughly 27-28 m onto an open wall that falls away into hundreds of metres of water. From there the standard dive is a drift south along the wall, past overhangs with black coral, to the saddle - a shallow coral sill at about 6-7 m - and then over it into the Blue Hole itself for the safety stop and exit. Done that way it is a normal advanced recreational dive, and dive centres rate it as such.
It is also the entry to the site with the worst fatality record in recreational diving, and that has to be stated in full rather than in a footnote. The Arch is a tunnel through the reef, 26 m long, whose ceiling Wikipedia places at 55 m and dive centres describe at 52-56 m, connecting the Blue Hole to the open sea. It is below recreational depth on air by any standard, it is a genuine overhead environment, and the hole itself bottoms out at just over 100 m with the seaward floor dropping past 1,000 m. Divers who miss the Arch on the way through, or who narc at depth and continue down, do not have a bottom to stop on.
Nobody knows the real death toll and the published figures should be treated as estimates, not facts. Wikipedia records an estimate attributed to local recovery diver Tarek Omar in 2012 of more than 130 divers in the preceding fifteen years, notes an alternative claim of as many as 200 for the same period, and says the counts include some surface snorkelling deaths. The Egyptian authorities do not publish figures. What is not in dispute is on the shore: a wall of memorial plaques left by families on the path to the site, and named cases including the instructor Yuri Lipski, who died on 28 April 2000 at 115 m in an uncontrolled descent that his own camera recorded, and the freediving safety diver Stephen Keenan, who died in the hole in July 2017 during a rescue.
None of that describes the Bells-to-Blue-Hole traverse, which thousands of people dive safely every year, and one Dahab centre puts it bluntly that this is not an inherently dangerous site when the training is respected. It describes what happens when divers go down the middle instead of along the wall. The occurrence records we hold here are unremarkable Gulf of Aqaba reef life - scalefin anthias, Klunzinger's wrasse, purple tang, sergeant majors, twoband anemonefish, giant clams, blackback butterflyfish - and the wall sometimes produces trevally, a turtle, or a passing shark.

Shore dive. Road access north of Dahab to the Blue Hole car park and its line of restaurants, then a short walk north along the shore path - past the memorial plaques - to the Bells entry. Kit is normally carried or driven up; you exit at the Blue Hole, not where you got in.
You can reach the site independently.
A shore giant stride, a short drop through the chimney to about 27-28 m, then a gentle drift south along a vertical wall to the saddle at 6-7 m and over into the Blue Hole. Dahab centres rate the current here light to moderate. Surface conditions on the shore platform matter more than anything in the water.
On current: Sources disagree on the recreational maximum and we take the conservative reading. The chimney exit is given at 27 m by one Dahab centre and as a swim-through at about 28 m by another; the standard drift then shallows steadily to the 6-7 m saddle. One operator advertises a 60 m maximum for AOW-plus divers and another says Deep Diver certification allows 40 m for a look at the Arch; we record 6-30 m as the recreational band because a 60 m air dive on this wall is exactly the profile that has killed people here. Current on the wall is rated light to moderate by the centres. We found no sourced visibility figure for the Bells specifically, so it is left blank.
The recreational dive drops through the chimney and exits at about 27-28 m, then shallows along the wall to the saddle at 6-7 m. That is the whole dive. The Arch is something else: a 26 m tunnel whose ceiling Wikipedia places at 55 m and dive centres describe at 52-56 m. It is below recreational limits and is not part of this route.
Nobody knows, and every published number is an estimate. Wikipedia records an estimate attributed to local recovery diver Tarek Omar in 2012 of more than 130 deaths in the preceding fifteen years, plus an alternative claim of as many as 200 for the same period, and notes that the counts include some surface snorkelling deaths. Egypt publishes no official figures. The memorial plaques left by families on the shore path are the part that is not in dispute.
Because the danger is optional and self-inflicted. The traverse along the wall is a normal advanced dive. The deaths come from divers attempting the Arch at 52-56 m on recreational gear and air: narcosis at depth, missing the tunnel, and a hole that bottoms out past 100 m with the open sea beyond dropping further still. There is nothing to stop a diver who keeps going down.
Not on a recreational certification. It is a genuine overhead environment at technical depth and needs appropriate mixed gas, training, equipment and support. One Dahab centre states plainly that without the correct training and equipment this is an extremely hazardous dive. Some operators offer a 40 m look down at it for Deep Diver-certified divers; that is a glimpse, not a traverse.
Dahab centres ask for Advanced Open Water or equivalent for the Bells-to-Blue-Hole route, because the chimney exits below 27 m. We record 6-30 m as the recreational band; one operator advertises up to 60 m for AOW-plus divers, which we deliberately do not adopt.
Shore dive, north of Dahab by road to the Blue Hole car park, then a short walk along the shore path to the Bells entry - past the memorial plaques. You giant-stride in at the Bells and exit at the Blue Hole, so gear and transport arrangements differ from a normal there-and-back shore dive.
Both are common. The water inside the hole is sheltered and Dahab is a major freediving destination, with one centre describing conditions here as perfect. But it is very deep water with no bottom under you, snorkelling deaths are included in the site's published counts, and freedivers have died here too - including the safety diver Stephen Keenan in July 2017. Do it with an established school and proper safety cover.
The dive is about the topography more than the fauna: a vertical wall with overhangs carrying black coral. Dive centres report trevally and the occasional turtle or shark. Our own occurrence records here are ordinary Gulf of Aqaba reef life - scalefin anthias, Klunzinger's wrasse, purple tang, twoband anemonefish, giant clams and blackback butterflyfish.

A 100 m shaft in the reef with a 6 m sill over the top. The ordinary dive here is a shallow swim; the reputation belongs to the Arch.
A quiet coral garden south of the Blue Hole, entered off a jetty when the wind allows.
A quiet slope of salad and table corals 300 m north of the Canyon, usually dived as a one-way drift back to it.
A roofed crack in the reef north of Dahab: an overhead environment with a recreational front door and a technical back one.
The shallow hard-coral garden that wraps around the Canyon: the same shore dive without the overhead.
A hotel house reef 300 m from Coral Garden, entered off a jetty, dived mostly by the people staying above it.
