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.

Escape the heat and visit a tea plantation in the rolling hills of the Cameron Highlands.

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.

Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.

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.

This charming city is a UNESCO world heritage site, with a rich trading history and multicultural heritage. Melaka is a rewarding town to explore and is about two hours from Kuala Lumpur.

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.

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.
