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 travellers with ferries and longboats to the best scuba diving, rock climbing and white sand beaches on the coast.

Phuket offers a rainbow spectrum of spectacular holiday sights from blue lagoons and pink sunsets to orange-robed monks. Three wheeled-Tuk Tuks, taxis, buses and long tailed boats transport visitors between these marvels. Phuket's south coast offers its most popular beaches. The north is more tranquil. Koh Phi Phi, Phang Nga Bay and Patong Beach are popular spots. Diving, snorkeling, wind surfing and sailing are just a few active options. Inland, forested hills, mountains and cliffs wait to be explored.

Party-hoppers flock to the wide and whimsical sands of Patong Beach. Mere minutes from the glittery chaos of Patong's many nightclubs, bars and discos, the golden beach is ideal for sunbathing, jet skiing, kayaking and parasailing. Lovers of leisure can spend the day relaxing on a sunbed under a colorful umbrella, lingering over treats from one of the vendors who stroll the sands.

The beauty and rich history of George Town keeps tourists flocking all year round. George Town offers views of the famous Cheong Fatt Tze Mansion, Kapitan Keling Mosque and many of the capital's golden crowned Buddhist temples.  With museums showcasing the country's rich-historical treasures, restaurants that offer classic Malaysian cuisine and dozens of shopping malls, there's guaranteed to be something for everyone to see.

The British colonial city of Ipoh had humble beginnings, but has blossomed into a beautiful cityscape that marries old-world charm with modern amenities. This is a foodie's city, offering endless street stalls and restaurants all eager to serve up a sample of mouthwatering local fare.

The cultural hub of Malaysia, Kuala Lumpur is visually defined by the iconic Petronas Twin Towers, which, at 88 stories high, are the tallest twin buildings in the world and a vision of modern architecture. On the flip side, the Sri Mahamariamman is the oldest Hindu temple in Malaysia, its façade a colorful totem pole of iconography. Shopping at the Central Market is a joyful experience that involves haggling, handicrafts, and happiness.

Johor Bahru is the second-largest city in Malaysia and, with the opening of two major amusement parks in 2012, it is poised to become a major tourist destination. TripAdvisor travellers also recommend visiting the Arulmigu Sri Rajakaliamman Glass Temple, a unique Hindu temple decorated with brilliant glass mosaics.

A bargain shopper’s delight is just across the causeway in Malaysia, with numerous bus and train services available to ferry travelers across the border. The largest and most popular malls are easily accessible from the checkpoint and offer a blend of name-brand and knockoff shopping. Dig deeper and you’ll appreciate the city’s differences, good and bad, from Singapore, though rumors of rampant crime are overblown. Museums and places of worship abound, along with good dining for any budget. A new premium outlet mall opened just outside the city in December 2011, and keep an eye on the new Legoland Malaysia, slated to open at the end of 2012.

Singapore is known as a bustling metropolis that also happens to be one of the cleanest and safest cities of its size in the world. (Just make sure you heed the local laws—something like spitting in the street might merely be considered rude in your hometown, but here, it carries a severe penalty.) You'll find historic sites like the Thian Hock Keng temple, superlative shopping (including gargantuan malls) and numerous beaches.

Where else can you find an azalea-framed volcano to climb, a sisterhood of deep-divers, and ancient stone statues on which to make wishes? Jeju Island. A favourite with newlyweds (and K-drama fans), this popular retreat is also home to miles of golden beaches, winding coastal trails, and Jeju Waterworld, the area’s largest water park. No matter what your fancy, one thing is for certain: a day of sightseeing isn’t complete without enjoying some of the isle’s delicious raw seafood and famed barbecued black pork.
