The quietest of the numbered Abu Dabbab reefs, and the one with the coral cover to show for it.
Abu Dabbab IV is the fourth of the numbered offshore reefs that Marsa Alam dive centres run as speedboat day trips. It is the least visited of the group, which is the main reason it is recommended: coral cover is described as richer than the neighbouring reefs and visibility generally better.
The dive works a large coral garden between roughly 12 and 22 m, scattered with pinnacles and coral tables, within an overall depth range of about 3 to 25 m. Operators rate it easy to medium with low to medium current and open it to all certification levels.
OBIS occurrence records here are the standard northern Red Sea reef assemblage and are essentially the same list as the adjacent reefs: sohal surgeonfish, bluespotted ribbontail ray, sailfin tang, masked butterflyfish, common lionfish, coral hind, royal angelfish, giant moray and titan triggerfish. Dive-centre accounts add crocodilefish, turtles, tuna and barracuda.
OW
Speedboat day trip from the Marsa Alam coast. No shore access and no facilities at the reef. The ticketed Marsa Abu Dabab bay - the seagrass lagoon known for dugongs - is a separate shore site, and its entry fee does not apply to this offshore reef.
Access to the site runs through a local operator.
Large coral garden at roughly 12-22 m with pinnacles and coral tables, within an overall 3-25 m range. The operating dive centre rates the site easy to medium with low to medium current. Visibility is described as generally very good and better than the neighbouring reefs, but no figure is published, so none is recorded.
On current: Rated low to medium by the operating dive centre. Visibility is described as generally very good but no figure is published, so none is recorded.


The overall range is about 3 to 25 m, and the part of it worth your bottom time is the coral garden between roughly 12 and 22 m, scattered with pinnacles and coral tables. That keeps a normal dive comfortably inside recreational limits.
Yes. The operating dive centre rates it easy to medium with low to medium current and opens it to all certification levels. There is no overhead environment and no deep component you are obliged to take.
Because it is the least visited of the numbered group, and dive centres describe its coral cover as richer than the neighbouring reefs and the visibility as generally better. Low traffic is the whole argument for it.
Speedboat day trip from the Marsa Alam coast; there is no shore access. Boats in the Egyptian Red Sea moor on HEPCA's buoy system rather than anchoring on the reef, a network of over a thousand buoys installed to keep hulls and chains off the coral.
It is not published as a snorkelling site. The reef does rise to around 3 m, so the tops are within reach from the surface, but the dive itself is a coral garden at 12-22 m that you will not see from above, and access is by dive boat only.
The occurrence record is the standard northern Red Sea assemblage, essentially the same list as the adjacent reefs: sohal surgeonfish, bluespotted ribbontail ray, sailfin tang, masked butterflyfish, common lionfish, coral hind, royal angelfish, giant moray and titan triggerfish. Dive-centre accounts add crocodilefish, turtles, tuna and barracuda.
No. The dugongs associated with the Abu Dabbab name graze the seagrass in Marsa Abu Dabab bay, a separate ticketed shore site, not at the numbered offshore reefs. Turtles, on the other hand, are reported across the group.

The fifth of the numbered Abu Dabbab reefs: a sandy slope with coral blocks and swim-throughs, and very little written about it.
The sixth and outermost of the numbered Sha'ab Abu Dabbab reefs, in the group a local dive guide says people rarely dive.
The third and larger of the offshore Abu Dabbab reefs: two facing pinnacles, narrow tunnels on the south side, and a burnt-out liveaboard in the channel next door.
A single fissure in the reef that takes fifteen to twenty minutes to swim, opening into chambers on the way through.
A horseshoe of two reefs closing around a shallow pool of coral gardens, 18 m at its deepest.
Almost certainly a duplicate catalogue entry for Abu Dabbab V: the fifth of the numbered offshore reefs, sandy slope, coral blocks, swim-throughs.
