Dahab's famous coral sinkhole — a wall of reef dropping into deep blue, and one of the Red Sea's iconic swims.
The Blue Hole at Dahab is a legend among divers and snorkelers alike: a near-perfect circle of deep water ringed by living coral, right off the shore. Float over the reef shelf, watch the wall fall away beneath you, and follow it up to Ras Abu Galum's remote coast. We pair it with the region's best-guided reef days.
