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.

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

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.

Forested hills, romantic white-sand beaches and crystal-clear waters greet visitors to tropical Palau Langkawi, the largest of the 99 islands in Langkawi archipelago.

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.

Shopping at the Central Market is a joyful experience that involves haggling, handicrafts, and happiness.

Bangkok is full of exquisitely decorated Buddhist temples—as you go from one to the next you’ll be continually blown away by the craftsmanship and elabourate details.

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.

You'll find historic sites like the Thian Hock Keng temple, superlative shopping (including gargantuan malls) and numerous beaches.

Kuching is a fine choice for an enriching vacation that's as packed with learning as it is leisure. Its many museums and impressive planetarium will enthrall even the tiniest travelers, and a quick climb to the top of the Kuching Civic Center will reward you with jaw-dropping 360-degree views. Grab a snack from a stall on the bustling waterfront, and don't miss the absolutely massive Sunday market, which is an electric experience for shoppers, vendors, and observers.

Don’t forget to eat as much sushi, udon noodles, and wagashi (Japanese sweets) as your belly can handle.
