The Blue Hole is a vertical 394-foot-deep underwater sink hole, located just a few miles north of the city of Dahab, Egypt. Not only is it one of the Red Sea’s most popular dive sites, it is also one of the most dangerous dive sites on the planet. When snorkeling the Blue Hole, you will explore just the edge of the Blue Hole. This area is colonized by a good diversity of corals, and it remains an exceptional underwater experience.

How to get to the Blue Hole snorkeling spot

The Blue Hole is located 4 miles/7km North of Dahab. Every day, a multitude of scuba divers, free divers, snorkelers and visitors make the journey from Dahab by jeep or camel, eager to discover and explore the Blue Hole.

Tours are organized every day from Dahab (from $20pp.) and Sharm el-Sheikh (approximately 60 miles south of Dahab). You can also get there in your own car, but you will need an all-road vehicle to cover the last 4 miles.

Water entrance for snorkeling the Blue Hole

You can get into the water from three entries. The two first entry points (water entrance 1 and 2 on the map above) are straight into the Blue Hole, a few yards from the shore. They are easily located by observing the other snorkelers and divers entering or exiting the water.

While you can get into the water by going straight into the Blue Hole, we recommend getting into the water at the northernmost entry point (water entrance 3). This spot is about 150 yards north of the Blue Hole, and is called “El Bells”. Since the prevailing current runs from north to south, it is better to enter the water at this point and let yourself drift slowly along the drop-off and enter the Blue Hole through “The Saddle”. The entrance is easy to find as there are usually scuba divers around the area.

Blue Hole snorkeling exploration tips

Exploring the Blue Hole consists of snorkeling along the vertical coral walls bordering the sinkhole (snorkeling area 1 on the map), 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 that we previously mentioned, (↕2-20ft/0.5-6m deep), known as “The Saddle”. This area opens out to the sea. It is probably the most interesting area. Here the seabed is the best preserved, with dense and multicolored corals.

Thousands of sea goldie take shelter around the coral, and a wide range of interesting fish, such as angelfish, clownfish in their sea anemone, wrasse and groupers can be seen here. In the Blue Hole, there are no strong currents and the water is calm, clear and warm.

The reef wall at Dahab's Blue Hole
Dahab’s Blue Hole reef drop-off is very steep, plunging vertically to the depth of the Red Sea.

If you enter the water on the entry point n.3, you will first drift along a reef drop-off opening to the sea before entering into the Blue Hole through “The Saddle” (snorkeling itinerary 2 on the map). In this area, the seabed has more or less the same profile as inside the Blue Hole, but corals are healthier overall.

The Blue Hole is very deep, do not explore this spot alone. Do not free dive if you are not trained to, and stay away from the drop-off. This site is truly one-of-a-kind, and one not to be missed. Just remember to use caution at the Blue Hole and know your limits.

The spot is very popular with scuba divers, free divers and snorkelers. There can be numerous people in the water; so keep an eye out for others all the time.

Restaurants and accommodation around the Blue Hole

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 choice of restaurants, supermarkets and accommodation for all budgets.

These spots are only recommended to good swimmers, in good physical conditions, and with excellent snorkeling skills. These spots can experience currents, moderate waves, important depths, tight or narrow passages, or tricky water entrance, and can be located near hazardous areas (channels, boat traffic, strong currents…). The distance to swim to reach the most interesting snorkeling areas can be important - up to 500 meters. The “advanced” category includes drift snorkeling (transported by currents) and snorkeling off the coast.

This level only apply when the spot experiences optimal sea and/or weather conditions.
