Diving The Canyon in Dahab: A Surreal Deep Experience

Descend into one of Dahab's most iconic geological wonders. A guide to diving The Canyon, its light effects, and what advanced divers can expect.

Diving The Canyon in Dahab: A Surreal Deep Experience

While the Blue Hole is Dahab’s most famous landmark, many experienced divers will tell you that The Canyon is the town’s most beautiful dive.

A masterpiece of underwater geology, The Canyon is a massive volcanic fissure in the seabed that creates a series of stunning light effects and cavernous spaces. It is an essential stop on any Dahab diving itinerary.

What is The Canyon?

Located just a few kilometers south of the Blue Hole, The Canyon is essentially a deep crack in the reef that has been partially closed at the top by coral growth over thousands of years. This creates an underwater dome or tunnel structure that divers can enter and explore.

It is not a 'cave' in the technical sense, as there is always a visible exit to the surface, but it offers a surreal, enclosed feeling that is rare in recreational diving.

The Dive Profile

The Entry: The Fishbowl

The dive begins with an easy shore entry into a shallow lagoon. You swim out over a beautiful coral garden until you reach 'the fishbowl'—a small, circular coral formation at about 12 meters where hundreds of tiny glassfish hide.

The Fissure

From the fishbowl, you descend along the seabed until you see the opening of the Canyon. The crack starts at about 15 meters and drops vertically. You descend through the main opening and glide down into the belly of the canyon.

The Bottom: 30 Meters

The deepest part of the recreational Canyon dive is a wide, sandy-bottomed chamber at 30 meters (100 feet). From here, you can look up and see the light filtering through the narrow crack above, creating celestial 'cathedral' light beams in the clear blue water.

Why It’s Special

• The Light: On a sunny day, the way the sunlight pierces through the narrow opening above is magical. It is a photographer's dream.
• The 'Bubbles': As you look up from the bottom of the Canyon, you will often see thousands of tiny silver bubbles 'raining' down from the ceiling. These are actually the exhaled air from divers who are swimming on the reef above the canyon, which filters through the porous rock.
• The Exit: Divers usually exit through a different, narrower crack at about 18 meters, popping back out onto the vibrant reef flat.

Requirements and Certification

Because the main floor of the Canyon is at 30 meters, this is strictly an Advanced dive.

• Certification: You must be a PADI Advanced Open Water Diver or equivalent to enter the deep chamber.
• Air Management: Being at 30 meters means your air will be consumed much faster. Your guide will monitor your gauge closely, as bottom time inside the canyon is relatively short.
• Buoyancy: Good buoyancy is crucial to avoid stirring up the fine sand on the bottom, which can ruin the visibility for yourself and other divers.

Technical Version: The Neptune’s Chair

For technical divers, the Canyon continues much deeper. The fissure extends beyond the recreational chamber, leading to Neptune’s Chair at 52 meters. This requires specialized training, gas mixes, and equipment.

Final Thoughts

Diving The Canyon is a serene, almost spiritual experience. Floating in the cool, blue air of the underwater dome while watching the light dance above is something you will never forget. It is the perfect companion to the vertical walls of the Blue Hole and a testament to the incredible natural beauty of the Sinai coast.
