The Blue Hole Egypt is an iconic place that is on many snorkelers and divers’ bucket list. This unique snorkeling, freediving, and diving spot, where desert sand meets the crystal clear water of the Red Sea is a must-see when in Dahab. Read here everything you need to know before visiting this famous submarine sinkhole.

How the Blue Hole Egypt was formed?

Blue holes are found all over the world on shallow carbonate platforms. They formed during past ice ages when sea level was 100-120 meters (330-390 feet) lower than now. These large marine caverns that are open to the surface, have developed in a bank or island composed of carbonate bedrock. The formations were formed through erosion from rain and chemical weathering until they submerged at the end of the ice age. They extend below sea level and may have accesses to submerged caves. They typically contain tidally-influenced water of fresh, marine, or mixed chemistry.



The deepest blue hole in the world is the Dragon Hole in South China Sea. It is 300.89 meters (987 feet) deep. The 2nd deepest is Dean’s Blue Hole (Bahamas), with an underwater entrance at 202 meters (663 ft). There are many famous Blue Holes around the world like The Blue Hole Gozo, Great Blue Hole Belize, Watling’s Blue Hole San Salvador, and of course The Blue Hole Egypt in the city of Dahab.

Blue Hole Freediving

You may enter the water directly at the Blue Hole through a small wooden jetty or at the nearby Bells. The Bells is the spot about 200 meters north of the hole, a small crack in the reef-table, perfect entry point for snorkelers! The best is to start snorkeling at Bells because of the currents. Usually, the current runs from north to south so it will take you down towards the hole while observing colorful corals and amazing blue water. Turn right and swim along the fantastic wall with loads of coral overhangs surrounded by the full variety of Red Sea fish. It is worth looking into the deep sometimes as there is a possibility to see some bigger fish.

If you decide to get into the water at the Blue Hole itself, use the marked entry points. Unfortunately, the inner ring is the hole is completely dead, you won’t find any healthy corals. You need to swim to the outer ring to see the amazing coral garden! Note that the hole is more than 100 meters deep, you won’t see the bottom if you swim in the middle. If you are a bit scared of depth, follow the ring on the left side which will take you to the outer reef.

Opposite the shore, you find a shallow opening called “saddle”. This is the most beautiful area full of vibrant corals and fish! You find here schools of sea goldies, bannerfish, anemonefish, wrasses and groupers. Snorkeling around the Blue Hole Egypt is safe, normally the sea is calm here without strong currents.
