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. But if you’d rather seek enlightenment in a gourmet meal, or dance the night away, you’ll also enjoy Bangkok—the restaurant and nightclub scenes here are among the best in the world.

The charming Vietnamese capital has aged well, preserving the Old Quarter, monuments and colonial architecture, while making room for modern developments alongside. Hanoi may have shrugged off several former names, including Thang Long, or "ascending dragon", but it hasn't forgotten its past, as sites such as Ho Chi Minh's Mausoleum and Hoa Lo Prison attest. Lakes, parks, shady boulevards and more than 600 temples and pagodas add to the appeal of this city, which is easily explored by taxi.

Vietnam's bustling largest city sets the cultural and economic pace for the country. The former Saigon boasts charming French colonial architecture and wide boulevards, usually thronged and choked with traffic. Taxis are an option for seeing the sprawling city. The War Remnants Museum shows the Vietnam War through Vietnamese eyes. Don't miss the impressive Jade Emperor Pagoda. Go to the frenetic Ben Thanh Market for food, flowers or frogs. Tour through the Mekong Delta, past rice paddies and houseboats.

Breathe deep in Genting Highlands where, unlike nearby Kuala Lumpur, the air is fresh and clean. Aside from its resort life, visitors flock to hill station to enjoy cooler temperatures, mountain scenery, strawberry farms, and a relatively undisturbed, natural rain forest.

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.

Just a speedboat ride from Singapore, Batam’s beaches and bars tempt visitors with dishes of chili crab, grilled lobster, and freshly caught fish. While travellers golf, snorkel, and spa-hop, the island’s traditional culture thrives in fishing villages built on wooden stilts.

Metropolitan Manila encompasses six cities and 12 towns. Located on Manila Bay in the South China Sea, and bisected by the Pasig River, the capital of the Philippines is historic and modern, rich and poor. A popular sight is the Intramuros, a walled area that was the capital during Spanish rule. Intramuros has retained old dungeons and gunpowder rooms but added art galleries and theatres. The city is filled with museums, shops, parks and churches, plus enough nightlife to last until dawn.

Chaotic, crowded, and cosmopolitan, Jakarta, the capital of Indonesia, is a city of contrasts. Home to millions of people from around the world, the city is a mixture of languages and cultures, poverty and wealth. The city boasts some of the best nightlife in Asia and some of the worst traffic. Every holiday, the locals escape the pollution and the crowds to enjoy relaxing diversions like Ancol Dreamland, an amusement area featuring water parks, beaches, golf courses, and a SeaWorld.

Residents of East Java’s steamy capital know how to catch a breeze—whether they’re lounging at rooftop bars or exploring side streets on bicycle-powered rickshaws. While the historic trading port bustles with modern commerce, ancient cultures mingle in the Arab Quarter and Chinatown.

From modern skyscrapers and neon lights to Buddhist temples, palaces and pagodas, Seoul is a fascinating mix of old and new.

For the best view of the city, go to the tower on Namsan, one of the mountains that encircle the city.
