Egypt is one of the easiest ways to get world-class reef and wreck diving on a short flight. Most underwater travel focuses on the Red Sea: Sinai for clear-water day boats and shore days in Dahab, the Hurghada corridor for classic wreck routes, and the quieter south near Marsa Alam for bays and wildlife. Expect lots of sunshine, warm water much of the year, and seasonal winds that can add surface chop on crossings. Egypt also rewards mixed groups: snorkelers get shallow coral gardens and calm lagoons, while divers can stack wrecks, drifts, and wall dives in the same week. Add two or three topside days for Cairo and Luxor, or keep it beachy with desert sunsets and seafood on the coast.
