Dahab enjoys large numbers of tourists. It is world-renowned for its windsurfing. Reliable winds provide superb flat-water conditions inside Dahab's sand spit. Further away from shore, wavy conditions couple with strong winds to provide formidable conditions for keen windsurfers. SCUBA diving, free-diving and snorkelling are also popular activities with many reefs immediately adjacent to waterfront hotels. The nearby Blue Hole-which is nicknamed as "The World's Most Dangerous Diving Site"- and Canyon are internationally famous dive spots.
