Blue Hole Dahab

About this site

The Blue Hole is a 160 m deep vertical shaft in the reef just north of Dahab, famous worldwide for its intense blue colour and tragic reputation among technical and freediving communities. Recreational divers explore the open 'saddle' at 6 m and the stunning arch passage at 55–60 m that opens to the open sea. Extreme depth, nitrogen narcosis, and the lure to dive deeper make this site genuinely dangerous without proper training.
