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.

The southern Thailand town of Krabi serves as base camp for exploring the province of the same name, a lush region of jungles, limestone cliffs and idyllic isles floating just offshore in the Andaman Sea. Buddhist shrines still used by local monks are tucked into the chambers of the town's top attraction, Tiger Cave. The riverside pier links travelers with ferries and longboats to the best scuba diving, rock climbing and white sand beaches on the coast.

A favorite getaway for Bangkok residents, Hua Hin is a pretty beachside town. Family friendly and relaxed, it lacks the all-night partying and seedier aspects that make other nearby beach resorts a haven for unsavory characters. Once a small fishing village, it was transformed into a royal resort, and it’s these close links with Thai royalty that ensure Hua Hin won’t become overdeveloped or lose its small-town vibe.

A visit to Pattaya is a wonderful way to explore the beaches along the Gulf of Thailand. Relaxed and family-friendly Jomtien Beach is a hot spot for watersports and seaside massages. The giant Buddha of Wat Khao Phra Bat keeps watch over the city, and the wooden Wang Boran Sanctuary of Truth pays homage to Buddhist and Hindu art and architecture. At night, tons of bars and strip clubs attract an adults-only crowd.

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.
