The Canyon is a dramatic underwater fissure in the reef just off Dahab's shoreline, a narrow crack in the coral platform that descends in stages, with walls pressing close on both sides and the light fading as you go deeper. It is one of the most photogenic dives in the Gulf of Aqaba, and a completely different experience from the open-wall diving at the Blue Hole.

The dive starts on the reef plateau at around 8–10 metres. You locate the canyon entrance, a slot in the reef floor, and descend into it. The walls are covered in coral and marine life, and the passage narrows and widens in sections, creating a series of chambers as you work downward. At around 26–30 metres the canyon opens into a broader base before rising again. Most divers turn here and ascend back through the upper canyon or exit over the reef top.

The Canyon rewards slow divers. The walls are covered in detail, nudibranchs, flatworms, moray eels tucked into crevices, glassfish filling the narrower passages. The light effect from above, filtered through the crack, shifts through blue and green as you descend. Photographers consistently rate it as one of the best dive sites in Dahab.

Current is generally absent inside the canyon. The enclosed nature of the dive means buoyancy control matters, silt disturbed by careless finning reduces visibility for the entire group. Long, slow fin strokes and awareness of trim are the technical demands here.
