The main island of Singapore is shaped like a flattened diamond, 42 km (26 miles) east to west and 23 km (14 miles) north to south. Near the northern peak is the causeway leading to West Malaysia—Kuala Lumpur is less than four hours away by car. It is at the southern foot where you will find most of the city-state’s action, with its gleaming office towers, working docks, and futuristic "supertrees," which are solar-powered and serve as vertical gardens. Offshore are Sentosa and over 60 smaller islands, most uninhabited, that serve as bases for oil refining or as playgrounds and beach escapes from the city. To the east is Changi International Airport, connected to the city by metro, bus, and a tree-lined parkway. Of the island's total land area, more than half is built up, with the balance made up of parkland, farmland, plantations, swamp areas, and rain forest. Well-paved roads connect all parts of the island, and Singapore city has an excellent, and constantly expanding, public transportation system. The heart of Singapore's history and its modern wealth are in and around the Central Business District. The area includes the skyscrapers in the Central Business District, the 19th-century Raffles Hotel, the convention centers of Marina Square, on up to the top of Ft. Canning. Although most of old Singapore has been knocked down to make way for the modern city, most colonial landmarks have been preserved in the CBD, including early-19th-century buildings designed by the Irish architect George Coleman.

Koh Samui is the most popular tourist destination on the Western Gulf coast, which isn't surprising, considering the island's gorgeous beaches, perfect weather, and sparkling blue, almost turquoise, water. Koh Samui has seen rapid development since the 1990s, and you'll encounter hotels in all price ranges.Koh Samui is half the size of Phuket, so you could easily drive around it in a day. But Koh Samui is best appreciated by those who take a slower, more casual approach. Most people come for the sun and sea, so they head straight to their hotel and rarely venture beyond its beach. But it's worth exploring beyond your lodging. Every beach has its own character, and you might find the perfect one for you. One beach many visitors find to their liking is Chawaeng. On Koh Samui's east coast, this stretch of glistening white sand is divided into two main sections—Chawaeng Yai (yai means "big") and Chawaeng Noi (noi means "little"). You'll find the greatest variety of hotels, restaurants, and bars here. Despite the crowds, Chawaeng is no Pattaya or Patong—the mood is very laid-back. A rocky headland separates Chawaeng Lamai Beach, whose clear water and long stretch of sand were the first place on the island to attract developers. More budget accommodations are available here than in Chawaeng, and there are some happening nightclubs.On the west coast of Koh Samui, Na Thon is the island's primary port and the spot where ferries arrive from the mainland. It's home to the island's governmental offices, including the Tourism Authority of Thailand, and there are banks, foreign-exchange booths, travel agents, shops, restaurants, and cafés by the ferry pier. A few places rent rooms, but there's really no reason to stay here—nicer accommodations can be found a short songthaew ride away.To the north and east of Na Thon lie a few beaches worthy of exploration. Laem Yai, 5 km (3 miles) north, has great seafood. East of here, a small headland separates two low-key communities on the northern shore, Mae Nam and Bophut Beach. Mae Nam is also the departure point for boats bound for Koh Phangan and Koh Tao . Just south of the Samui's northeastern tip you'll find sandy Choengmon Beach, a good area for swimming that's not overdeveloped.

Bangkok, also known as the City of Angels and Venice of the East thrills with energy. There's such a vast array of sightseeing, shopping, and eating possibilities that you'll have little time to rest. When you do find a moment, pamper yourself with spa treatments, skyline-view bars, luxurious hotels, and excellent restaurants. The city is a mesmerizing blend of old and new, East and West, and dizzying contradictions. Temples and red-light districts, languid canals and permanent gridlock, streetside vendors and chic upscale eateries, all make their home together, all at the same time. Bangkok rarely fails to make an impression, and yes, you might need to go spend a few days on the beach to recover from it all. Although Bangkok is not known for jaw-dropping tourist attractions, it does have an endless supply of worthwhile pilgrimages. The Grand Palace, Wat Phra Kaew, and the Emerald Buddha are tops on every visitor's itinerary, and lesser-known temples, such as Wat Benjamabophit, the golden stupa of Wat Sakhet, and Wat Suthat, are all worthy of a stop. Besides temples, there are plenty of other interesting niches and touring possibilities to fit just about every interest. Take in a venom extraction and python feeding show at the Queen Saowapha Snake Farm, or go to the nearby Jim Thompson House to learn all about the famed Thai silk industry. If architecture is your forte, there is the Suan Pakkard Palace with its antique teak house collection, and the even more astounding Vimanmek Palace, which contains the world's largest golden teak building. Bangkok's Chinatown merits at least a day on every travel itinerary—be sure to check out the sprawling labyrinthine Flower and Thieves markets. Thai food is unrivaled for spice, taste, and variation. From multicourse meals to small street vendors, the one constant here is fresh and delicious at every level. You can have superlative roast duck or wonton noodles on a street corner for lunch and then be dining on world-class chef creations in the Oriental or Shangri-La hotels for supper. It doesn't have to be all spicy Thai either, as Bangkok is home to excellent French, Italian, and other world cuisines, and you need a few years just to make a dent in all the options that are available. The Old City is a major destination for travelers, as it's home to opulent temples like Wat Po and Wat Phra Kaew. Across the river is Thonburi, a mostly residential neighborhood, where you can find Wat Arun. At the northern tip of the Old City is Banglamphu, one of Bangkok's older residential neighborhoods. It's best known now for Khao San Road, a backpacker hangout, though the neighborhood has much more to offer, especially when it comes to street food. North of Banglamphu is Dusit, the royal district since the days of Rama V. East of the Old City is Chinatown, a labyrinth of streets with restaurants, shops, and warehouses. Farther down the Chao Phraya River is bustling Silom Road, one of the city's major commercial districts. Patpong, the city's most famous of several red-light districts, is also here. Bang Rak is home to some of the city's leading hotels: the Mandarin Oriental, the Peninsula, the Royal Orchid Sheraton, and the Shangri-La. To the north of Rama IV Road is Bangkok's largest green area, Lumphini Park. Continue north and you reach Sukhumvit Road, once a residential area. More recently, Thong Lor, farther east along Sukhumvit, has become the "in" neighborhood for those want to see and be seen. The Nana and Asok areas of Sukhumvit are now home to the even busier red-light entertainment districts (Nana and Soi Cowboy) than Patpong.

Sihanoukville is the premier beach destination in Cambodia for tourists and Cambodians alike, with golden white sands, tropical islands and mangrove jungles. A relatively new city, it sprang to life in 1955 with the construction of the only deep-sea port of a newly independent Cambodia. With the bay of Thailand surrounding it on three sides, Sihanoukville was named in honour of the former King Norodom Sihanouk in 1964. As Cambodia descended into civil war the town fell on hard times with the Khmer Rouge using the famous Independence Hotel for target practice. In 1993 peace returned to Cambodia and since then Sihanoukville has been slowly rebuilding itself. Today it attracts Asian Individual travellers, young students and back-packers but after decades of war and upheaval the town’s infrastructure is still very much in its infancy. A visit to Ream National Park offers pristine mangrove forests rich in wildlife with miles of beaches unmarked by footprints.

Romantically referred to by the French as the Pearl of the Orient, Ho Chi Minh City today is a super-charged city of sensory overload. Motorbikes zoom day and night along the wide boulevards, through the narrow back alleys and past vendors pushing handcarts hawking goods of all descriptions. Still called Saigon by most residents, this is Vietnam's largest city and the engine driving the country's current economic resurgence, but despite its frenetic pace, it's a friendlier place than Hanoi and locals will tell you the food—simple, tasty, and incorporating many fresh herbs—is infinitely better than in the capital.This is a city full of surprises. The madness of the city's traffic—witness the oddball things that are transported on the back of motorcycles—is countered by tranquil pagodas, peaceful parks, quirky coffee shops, and whole neighborhoods hidden down tiny alleyways, although some of these quiet spots can be difficult to track down. Life in Ho Chi Minh City is lived in public: on the back of motorcycles, on the sidewalks, and in the parks. Even when its residents are at home, they're still on display. With many living rooms opening onto the street, grandmothers napping, babies being rocked, and food being prepared, are all in full view of passersby.Icons of the past endure in the midst of the city’s headlong rush into capitalism. The Hotel Continental, immortalized in Graham Greene's The Quiet American, continues to stand on the corner of old Indochina's most famous thoroughfare, the rue Catinat, known to American G.I.s during the Vietnam War as Tu Do (Freedom) Street and renamed Dong Khoi (Uprising) Street by the Communists. The city still has its ornate opera house and its old French city hall, the Hôtel de Ville. The broad colonial boulevards leading to the Saigon River and the gracious stucco villas are other remnants of the French colonial presence. Grisly reminders of the more recent past can be seen at the city's war-related museums. Residents, however, prefer to look forward rather than back and are often perplexed by tourists' fascination with a war that ended 40 years ago.The Chinese influence on the country is still very much in evidence in the Cholon district, the city's Chinatown, but the modern office towers and international hotels that mark the skyline symbolize Vietnam's fixation on the future.

Hue (pronounced hway), bisected by the Perfume River and 13 km (8 mi) inland from the South China Sea, in the foothills of the Annamite Mountains (Truong Son Mountains), stands as a reminder of Vietnam's imperial past. The seat of 13 Nguyen-dynasty emperors between 1802 and 1945, Hue was once Vietnam's splendid Imperial City. Although it was devastated by the French in the 19th century and again by fighting between the Vietnamese Communists and the Americans in the 20th, the monument-speckled former capital has a war-ravaged beauty. One can still imagine its former splendor, despite gaping holes in its silhouette. Hue is a UNESCO World Heritage Site, and the city's gems are slowly being restored.

The Hong Kong Island skyline, with its ever-growing number of skyscrapers, speaks to ambition and money. Paris, London, even New York were centuries in the making, while Hong Kong's towers, bright lights, and glitzy shopping emporia weren't yet part of the urban scene when many of the young investment bankers who fuel one of the world's leading financial centers were born. Commerce is concentrated in the glittering high-rises of Central, tucked between Victoria Harbor and forested peaks on Hong Kong Island's north shore. While it's easy to think all the bright lights are the sum of today's Hong Kong, you need only walk or board a tram for the short jaunt west into Western to discover a side of Hong Kong that is more traditionally Chinese but no less high-energy. You'll discover the real Hong Kong to the east of Central, too, in Wan Chai, Causeway Bay, and beyond. Amid the residential towers are restaurants, shopping malls, bars, convention centers, a nice smattering of museums, and—depending on fate and the horse you wager on—one of Hong Kong's luckiest or unluckiest spots, the Happy Valley Racecourse. Kowloon sprawls across a generous swath of the Chinese mainland across Victoria Harbour from Central. Tsim Sha Tsui, at the tip of Kowloon peninsula, is packed with glitzy shops, first-rate museums, and eye-popping views of the skyline across the water. Just to the north are the teeming market streets of Mong Kok and in the dense residential neighborhoods beyond, two of Hong Kong's most enchanting spiritual sights, Wong Tai Sin Temple and Chi Lin Nunnery. As you navigate this huge metropolis (easy to do on the excellent transportation network), keep in mind that streets are usually numbered odd on one side, even on the other. There's no baseline for street numbers and no block-based numbering system, but street signs indicate building numbers for any given block.
