Dahab lies 80 kilometers north of Sharm el-Sheikh, and many of its visitors claim, with some justification, that it has a more relaxed and calm atmosphere than Sharm el-Sheikh.
The Blue Hole is one of Egypt’s more infamous dive sites on account of the high number of fatalities there.
Situated 12 km north of Dahab and 1.5 km from The Canyon, which is more famous than infamous, the Blue Hole is, strangely enough, a large hole in the reef – 150m wide and 110m deep.
The Blue Hole is connected to the sea via a 26m sea tunnel with a ceiling depth of 52m. For recreational divers, the Blue Hole itself is of little interest – its walls are rather barren, with a few hard corals (probably due to sunlight only being able to penetrate the hole to about 15-20m) – but it is a different story for technical divers, who seem to swarm the Hole like flies on a camel.
