Blue Hole

The Blue Hole is a vertical 394-foot-deep underwater sink hole, located a few miles north of the city of Dahab. It isn’t just one of the Red Sea’s most popular dive sites, it is also one of the most dangerous dive sites in the planet. Many intrepid divers perish in its depths every year. In snorkeling, you will just move along the edge of the Blue Hole, colonized by a good diversity of corals, but it remains an exceptional underwater experience.
How to get there?

The Blue Hole is located 4 miles (7km) North of Dahab. Every day, many scuba divers, free divers, snorkelers and onlookers make the journey from Dahab by jeep or camel, eager to discover and explore the Blue Hole. Many tours are organized daily form Dahab (from $20pp.) and Sharm el-Sheikh (approximately 60 miles south of Dahab). You can also get there with your own car, but you will absolutely need an all road vehicle to cover the last 4 miles.

Water entrance

You can get into the water in three points. The two first entry points (n°1 and n°2) are facing the Blue Hole, a few yard from the hole edge. You will easily locate them by observing the other snorkelers and divers entering the water (you will rarely be alone).

However, we recommend getting into the water on the entry point n°3 (see map above), some 150 yards north of the Blue Hole. Since the prevailing current runs from north to south, it is better to enter the water on this point and let yourself slowly drift along the drop-off, and enter the Blue Hole through the “saddle”. Ask the local people present to point this entry point (a small canyon) to you.

Aerial view


Snorkeling the Blue Hole consists in moving along the vertical coral walls surrounding the sink hole, where large shoals of surgeonfish, couples of butterflyfish and small groups of Red Sea bannerfish find shelter. Opposite the shore, there is a shallow opening (2-20ft/0.5-6m deep), known as "the saddle", opening out to the sea. This is probably the most interesting area. Here the seabed is the best preserved, with dense and multicolored groups of corals. Thousands of sea goldie take shelter around the coral, and a wide range of interesting fish (angelfish, clownfish in their sea anemone, wrasse and grouper) can be seen. In the Blue Hole, there are no disturbing currents and the water is calm, clear and temperate.

If you enter the water on the entry point n°3, you will first move along a reef drop-off opening to the sea, before entering into the Blue Hole through the “saddle”.

The Blue Hole is possibly the deadliest dive site on Earth. Many intrepid divers perish in its depths every year, braving the 80 yard wide hole. The Blue Hole is very deep, do not explore this spot alone, do not practice apnea if you are not trained to, and stay close from the drop-off. The spot is very popular with scuba divers, free divers and snorkelers, who can be numerous in the water; so keep an eye out for others all the time.

Restaurants and accomodation

There is a choice of budget accommodation and restaurants on the site. In Dahab, 4 miles south of the Blue Hole, you can find a whole host of restaurants, supermarkets and accommodation for all budgets.
