Top Dive Sites
Site 1: The Blue Hole
Description: The Blue Hole in Dahab is a world-famous dive site known for its iconic vertical drop, starting from the shallow lagoon and plunging to more than 100 meters. This submarine sinkhole boasts vibrant coral walls that create a visually striking underwater canyon.
Marine Species: Divers here often encounter a diversity of marine life including jacks, groupers, and trevallies. Coral gardens sheltering damselfish and lionfish are also a common sight.
Unique Encounters: One of the unique features of the Blue Hole is its prominent archway at about 56 meters. This arch, dotted with corals, attracts experienced technical divers from around the globe.
Photography: The sheer vertical walls and abundant sunlight penetration offer excellent opportunities for wide-angle photography. Macro photographers can indulge in capturing the intricate details of the coral reefs and small marine creatures.
Suitability: This dive site is suitable primarily for advanced and technical divers, particularly those aiming to explore the arch at deeper levels. The drop-off and depth require experience and familiarity with deep diving protocols. Beginners can enjoy the shallow lagoon area but should proceed with caution.
Site 2: The Bells
Description: The Bells is a dive site that accompanies the Blue Hole, located just to its north. It starts with a narrow, vertical descent into a cavernous chimney that opens up to the coral wall, leading divers directly to the Blue Hole.
Marine Species: The reef along the Bells attracts a variety of marine life such as angelfish, triggerfish, and barracudas. The narrow entryway is often teeming with anthias and wrasse.
Unique Encounters: The initial descent through the chimney is a thrilling experience. Within the cavern, the walls are laden with colorful sponges and corals, which are home to numerous crustaceans and invertebrates.
Photography: The contrast between the dark chimney and the light blue exit is perfect for dramatic underwater photography. Out in the open reef, wide-angle shots of the stunning underwater topography are a must. It’s also an excellent spot for macro shots among the corals.
Suitability: This site is more suited for advanced divers due to the narrow and vertical entry. Divers should be comfortable with descending in confined spaces and buoyancy control before emerging into open water.
Site 3: El Bells to Blue Hole
Description: This dive route combines both The Bells and the Blue Hole sites, offering a continuous underwater journey. Starting at The Bells, divers make their way down the chimney and traverse along the outer reef wall before entering the Blue Hole.
Marine Species: During this drift dive, you can see a diverse array of marine species, including parrotfish, butterflyfish, and, with a bit of luck, even hawksbill turtles. The coral walls teem with various species of sponges and gorgonians.
Unique Encounters: As you make your way along the reef wall, look out for larger pelagic species such as tuna and barracuda in the blue. The seamless transition from the open reef into the celestial Blue Hole is a significant highlight of this dive.
Photography: This route offers ample opportunities for capturing the magnificent underwater scenery, from the shadowy confines of the Bells to the illuminated, coral-clad walls of the Blue Hole. Continuous shots can narrate the diver’s journey from one site to the other.
Suitability: This extended dive route demands not just advanced diving skills but also good air management and navigation abilities. It offers a thrilling experience for seasoned divers looking to explore two iconic sites in one dive.
Considerations for Each Dive Site
Water Temperature: The Blue Hole in Dahab offers a pleasant water temperature averaging between 23°C to 28°C (73°F to 82°F). During the summer months, temperatures can push towards the higher end of this range, while winter might bring slightly cooler waters. This range makes it suitable for diving year-round, with a wetsuit thickness of 3-5mm generally being adequate.
Visibility: Visibility in the Blue Hole is typically excellent, often ranging from 20 to 30 meters (65 to 100 feet). The crystal-clear waters provide divers with superb conditions to explore the intricate underwater landscapes and observe marine life in detail. However, visibility can slightly decrease during the winter months due to plankton blooms.
Currents and Tides: The Blue Hole is known for its calm conditions, with minimal to light currents making it a favorite spot for divers seeking a relaxing dive. However, it’s important to be aware of the occasional strong currents at the Bells, the external reef leading to the Blue Hole. These currents can funnel divers into the Blue Hole itself, so advanced planning and guidance from local dive operators are essential.
Safety Tips:
- Always dive with a guide familiar with the Blue Hole’s unique features and potential risks.
- Ensure your buoyancy control is honed, especially when navigating the deeper sections of the hole.
- Monitor your depth carefully. The Blue Hole’s depth can be tempting, but it’s crucial to stay within your certification limits.
- Be cautious of the arch, which can be challenging and requires technical diving certification to attempt safely.
- Begin your dive early in the day to avoid overcrowded conditions and maximize the visibility and tranquility of the site.
Regulations:
- Divers are required to show their certification and logbook before diving at the Blue Hole.
- Technical divers must have appropriate certification and should dive with a professional guide familiar with deep diving conditions.
- Respect the local marine life and underwater environment by avoiding contact with coral and not disturbing the habitat.
- Use a dive computer to track your depth and time accurately, ensuring you adhere to decompression limits.
- Dispose of any waste responsibly and adhere to ‘leave no trace’ principles to preserve the site for future divers.
