The Blue Hole
is a diving location on the southeast Sinai, a few kilometers north of Dahab
A shore dive and the view is magnificent in this spot where the mountain meets the sea.
The Blue Hole is a submarine sinkhole, with a maximum depth within the hole of just over 100 m (328 feet). There is a shallow opening to the sea around 6 m (20 feet) deep, known as "the saddle", and a 26 m (85 feet) long tunnel, known as "the arch", whose top is at a depth of 55 m (181 feet), and whose bottom falls away as it reaches the seaward side to about 120 m (394 feet).
On the seaward side the depth drops steeply to over a thousand meters (3500 feet) deep.
The hole and the surrounding area have an abundance of coral and reef fish
