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.

Come play in El Gouna where the turquoise Red Sea sparkles. With resorts, spas and an 18-hole golf course, El Gouna lets you unwind under the sun. Book an excursion by land or sea—quad bikes are a popular way for the adventurous to see the desert. By night, trendy bars and the open-air disco welcome you to stay up late.

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. Long known as a laid-back, backpacker-friendly town, Dahab is becoming more developed, yet retains a casual vibe. Finally, Dahab is also home to the Blue Hole, the world's most dangerous dive site. Only very experienced technical divers should attempt passage through "The Arch" here; if you're a novice diver, stay close to the surface.

Located on the Red Sea Riviera and nestled between a desert and a mountain range, Makadi Bay has beautiful, white sand beaches and crystal blue water. Interesting nearby excursions include trips to Giftun Island National Park, the Monasteries of St. Anthony and St. Paul or to the ancient town of Luxor, along the Nile River. In Makadi Bay, enjoy the beach, go camel or horseback riding and listen to live music at one of the many bars.

Traditional attitudes prevail in the historic Sinai region on Egypt's border with Israel. The triangular peninsula is divided from the rest of Egypt by the Suez Canal and the Red Sea. Craggy mountains, including 7500-foot Mount Sinai, plunge down to the waters of the Red Sea. Spectacular snorkeling and diving sites beckon from the Gulf of Aqaba to the east of the peninsula, particularly along the dramatic coastline of Na'ama Bay in Sharm el Sheikh. Camelback safaris offer distinctive desert excursions.

Thanks to the addition of an international airport in 2001, Marsa Alam is fast becoming a premium tourist destination, especially for scuba divers. The waters here are brimming with marine life and pristine dive sites. Landlubbers, don’t miss the Emerald Mines and the Temple of Seti I at Khanais.

The Zanzibar Archipelago, located in the Indian Ocean 15 miles off the coast of Tanzania, is a breathtaking spot to escape from the world. You’ll enjoy clear, turquoise-blue water; shallow sandbars perfect for wading; and many small, nearly deserted islands virtually unvisited by tourists. Explore the World Heritage Site of Stone Town, Zanzibar City’s old quarter. Or just go beach to beach between tiny fishing villages—each one's better than the next.

Want to make your co-workers insanely jealous? Just casually drop "I’m vacationing in the Maldives this year" into conversation, preferably in the dead of winter. Or better yet, go there without mentioning it to anyone—then send them a "Wish you were here!" postcard.

The nine islands that make up the Azores are in fact the peaks of some of the world's tallest mountains, reaching from deep beneath the Atlantic. The once-uninhabited, volcanic archipelago now hosts thousands of tourists every year who flock to the islands for sun, sand and verdant mountain scenery. From the beaches of Praia da Vitoria to the bustling marina of Horta, to the bubbling volcanic ground "ovens" of Furnas, these islands offer unparalleled--and unusual--adventures to discover.

Mauritius is arguably Africa’s wealthiest destination, a tropical paradise with tons to do. Port Louis, the modern capital of this 38-mile by 29-mile island, is a bustling port with a revitalized waterfront and a busy market. But most visitors gravitate toward resort areas such as Mont Choisy, quiet Trou-aux-Biches and the more bustling Flic en Flac, popular with scuba divers. Rivière Noire is ideal for those looking for great deep-sea fishing.

Sparsely-populated beaches that give way to an ocean brimming with interesting marine life and coral gardens are just one of the reasons to visit the beautiful Andaman and Nicobar Islands. Ghandi Park, Sippighat Farm and the century-old Cellular Jail (now a pilgrimage destination) provide glimpses into the past and present of these peaceful islands with a mysterious and multicultural past.

Just 80 kilometers north of Phuket, Khao Lak was essentially erased by the 2004 tsunami. But the town, and the tourist industry it relies on, has rebounded. It remains quieter than other coastal destinations, offering secluded beaches, tranquil nights and family-oriented activities. You want full moon parties and besotted nights? You’re out of luck. But if you’re looking for unparalleled scuba diving in the Similan Islands, you’ve hit the jackpot.

Thailand’s largest island is an international magnet for beach lovers and serious divers, who enthusiastically submerge themselves in the Andaman Sea. Blue lagoons and salmon sunsets make for a dream-like atmosphere, and indeed, a vacation here can feel a bit surreal. Watersports are the most popular activities, though once you’ve had enough sun there’s still plenty to explore at the island’s aquariums, gardens, and Buddhist temples.

Drifting serenely in the Gulf of Thailand, the palm-fringed island of Ko Tao takes its name from the abundant sea turtles that reside on its shores. White sand beaches sheltered by steep hills – some only accessible with four-wheel drive vehicles – and 300 days of sun per year invite long afternoons of lounging.

Koh Samui was once a Thai fishing community, and that charming sensibility is still present today. Spending time in Bophut is a wonderful way to soak up local culture; the beachy village restaurants and pubs are perfect spots to experience the sunset. There aren’t many other places where you can bask in the camp of a cabaret show and the solemnity of a Buddhist temple. As far as the latter goes, Wat Plai Laem is a magnificent vision of gilded red rooftops and a massive spindly-armed statue of Guanyin.
