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.

Langkawi is a serene archipelago of 140 islands – only a few of which are inhabited. The largest of these is the eponymous Langkawi Island, which has UNESCO World Geopark status because of its richly populated (by wildlife, that is) conservation areas. The best way to experience these ecological wonders is from high above, on the Langkawi Sky Bridge that stretches above the rainforest. Cheekily-named Pregnant Maiden freshwater lake is a great place to take a dip or play keep-away with the kleptomaniac monkeys.

Sprawling tea plantations surround the serene hills of Munnar, which attract adventure travelers hungry for paragliding, treks to Anaimudi (South India's highest peak) and hikes originating at the confluence of three mountain streams. The stone Christ Church, built by the British in 1910, is adorned with renowned works of stained glass, and Eravikulam National Park, about 10 miles away, is home to equally colorful wildlife, including the endangered Nilgiri Tahr (ibex), ruddy mongoose and 120 bird species.

Bali is a living postcard, an Indonesian paradise that feels like a fantasy. Soak up the sun on a stretch of fine white sand, or commune with the tropical creatures as you dive along coral ridges or the colorful wreck of a WWII war ship. On shore, the lush jungle shelters stone temples and mischievous monkeys. The “artistic capital” of Ubud is the perfect place to see a cultural dance performance, take a batik or silver-smithing workshop, or invigorate your mind and body in a yoga class.

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.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment. Catch a show at the Dubai Opera, see downtown from atop the Burj Khalifa and spend an afternoon along Dubai Creek exploring the gold, textile and spice souks. If you’re looking for thrills, you can float above the desert dunes in a hot air balloon, climb aboard a high-speed ride at IMG Worlds of Adventure or skydive over the Palm Jumeirah.

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.

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.

Even if you’ve never been to this Cyclades island in the Aegean Sea, you’d still recognize it immediately – candy-colored houses carved into cliffs, sapphire waters, gleaming white buildings topped with half-spheres the color of a stormy sky. Here you’ll find peace as you roam the black sand beaches or the streets of a provincial village like Imerovigli. Beautiful Oia is world famous for its sunsets, which seem tinted with every shade of an artist’s palette.
