Blue Hole is Egypt's and the world's most famous diving site. A natural vertical sinkhole dropping over 100 meters into the Red Sea. Famous for the Arch at 55 meters depth, a tunnel connecting the hole to open sea. The hole itself has a shallow entry at 6 meters called the Saddle. Perfect for snorkeling on the surface where you can see divers below, or recreational diving along the edges. The Arch is for certified technical divers only (Tech 60 minimum). A policeman now stations here to ensure safety compliance.
