Site details

The Blue Hole is a roughly 100 m-deep submarine sinkhole in the fringing reef just north of Dahab. Recreational divers explore the shallow rim and the saddle linking it to the open sea, while the famous Arch tunnel at around 52 m is reserved for technical divers. It is notorious worldwide for fatalities among divers attempting the Arch beyond their limits.
