Located just north of Dahab on the Sinai Peninsula, the Blue Hole is one of the most legendary and visually stunning diving locations in the world. Formed as a submarine sinkhole from eroding limestone during past ice ages, this natural wonder reaches breathtaking depths of approximately 130 meters.
Whether you are an experienced scuba diver, a free-diver, or a casual snorkeler, visiting the Blue Hole is an absolute bucket-list experience when exploring the Red Sea.
Geological Marvel & Marine Haven
The Blue Hole is a nearly perfect circular shaft with a diameter of about 100 meters. It is instantly recognizable by its deep sapphire waters that contrast sharply with the surrounding shallow turquoise reefs.
The site is home to vibrant coral walls and a flourishing array of Red Sea marine life:
Abundant Reef Fish: Clouds of bright orange anthias, colorful parrotfish, majestic lionfish, and large groupers around every corner.
Pelagic Visitors: Frequent sightings of tuna, barracuda, and occasional open-ocean visitors like whale sharks or dolphins swimming past the drop-off.
Iconic Dive & Snorkel Routes
The site features several unique underwater geography entry and exit points:
The Bells: The most popular entry point for recreational divers. It is a narrow, vertical rock chimney (or "chute") where divers descend down to about 28 meters before exiting onto a dramatic, sheer reef wall that drops hundreds of meters into the deep blue.
The Saddle: A shallow reef opening (about 6–7 meters deep) that connects the Blue Hole directly to the open sea. It serves as the primary entry and exit point for snorkelers and beginner divers.
The Arch: An infamous 26-meter-long underwater tunnel connecting the sinkhole to the open ocean at a depth of roughly 52–56 meters. Note: Passing through The Arch requires specialized technical diving equipment and advanced training.
Respecting the Site & Diving Limits
Because of its extreme depths, the Blue Hole requires respect and strict adherence to safety limits. While recreational diving along the reef wall and snorkeling near The Saddle are completely safe and suitable for all levels, attempting deep technical penetration through The Arch without proper certification or equipment poses serious risks, such as nitrogen narcosis.
A somber Memorial Wall on the nearby cliff faces serves as a respectful reminder to all visitors to honor safety protocols and stay within their training limits.
Visiting Details & Practical Tips
Easy Accessibility: It is a shore-access dive, meaning you can walk directly into the water straight from the beach.
Seaside Facilities: The shoreline is lined with relaxing, Bedouin-style cafes where you can relax on floor cushions, enjoy fresh meals, and sip traditional Bedouin tea between swims.
Best Time to Visit: The site is open year-round, but May to November offers the absolute best water visibility (20–30+ meters) and warm temperatures (up to 28°C).
