Saudi Red Sea
The frontier
Newly opened, lightly dived, still being built — reef that tourism has barely touched.
Saudi Arabia's Red Sea coast is the newest and least developed snorkeling region in this catalog, and both halves of that sentence are the point. The country opened to leisure tourism in 2019 with an e-visa, and the reef along the northern coast — Umluj, Al Wajh, the huge Al Wajh Bank offshore, Yanbu, and the NEOM project's Sindalah island — has seen a small fraction of the diving pressure that Egypt's coast, a few hundred kilometres north-west, handles every season. What that means in practice is genuine frontier reef alongside genuine frontier logistics: licensed snorkel and dive operators are few, what exists changes quickly, and a lot of the best water is a boat day or a liveaboard away rather than a walk off a beach.
