The dive

There are glassfish in the cracks. Next to it lies the Fish Bowl, a small grotto full of glassfish; it is closed.

The Fish Bowl has been closed to divers since late 2007 (after years of too much traffic): don't go in and don't exit up its chimney. Go in and out where your guide does.
Beyond 30 m the crack narrows and runs on to an exit at 45–55 m: only with deco training (Extended Range) and a gas plan. On air the narcosis there is severe.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): the websites of Circle Divers, H2O Divers Dahab and Scuba Seekers, PADI (Blue Hole/Bells, with pin), Wikipedia (Blue Hole, coordinates), Wikivoyage, duikersgids.nl (Abu Helal), SSI, Wego (July 2026) and Aquarius Red Sea (April 2026) on access and rules, and DAN Europe's Alert Diver (2013, 2016) on the chambers. These are shore dives on the reef: chimneys, canyons, overhangs and the Blue Hole's deep arch, with open water outside. The Arch and Abu Helal's deep canyon are technical deep dives. Certification and configurations are estimates.
