Nabq Bay is pristine and peaceful, thanks in large part to its status as a protected area. Here, mingle with dozens of species of flora and fauna amid the mangroves or dive into the sparkling water to explore the nearby coral reef. "Wild" (unguided) snorkeling is popular here—happy swimmers bob along as peacefully as the undisturbed wildlife. More adventurous travelers can venture into the desert on one of the many popular quad tours.

Stunning coral reefs and turquoise waters perfect for windsurfing have made Hurghada, on Egypt's Red Sea Coast, a busy resort town. Within easy reach of the stunning Giftun Islands and the Eastern Arabian Desert, Hurghada has seen enormous amounts of development in the past decade—and yes, it does seem overrun with tourists at times. But it’s a relatively easy beach escape for Europeans, and some of the world's best diving and snorkeling sites are just offshore. Walk or catch a cab to explore the old quarter, El Dahar.

This former Bedouin fishing village is now a popular tourist destination—especially for serious windsurfers, who'll find some of the best conditions in the world off Dahab's beaches.
