Blue Hole

Overview

"Blue Hole! This site is probably one of the most dangerous dive sites in the world, which magically captivates divers and snorkellers from all over the world and is now considered one of the most visited dive and snorkelling sites in the world!

Description

This enormous hole along the coast in the coral reef with a diameter of 50 to 65 meters, is located 10 km north of Dahab in the east of the Sinai Peninsula. The drop-offs reach depths of considerable 70 to 110 meters.

The Blue Hole is a large hole in the reef top of the coastal fringing reef, which drops vertically to depths of 70 meters to 110 meters. It has a diameter of 50 to 65 meters.
The reason why the Blue Hole is considered the most dangerous dive site in the world is because of a connection to the open sea, which is called an "arch" because of its shape. It extends from the bottom of the Blue Hole up to a depth of 55 meters. At its upper end it is only a few meters wide and about 26 m long. Also at the outer edge the reef forms an almost vertical drop-off, which continues below the "exit" of the Blue Hole as a steep slope down to several hundred meters depth.

Hotspots

• Most dives are conducted along the outer drop-off of the reef.
• The entry point is usually the dive site "Bells", which is located about 150 meters away from the Blue Hole.
