A visit to the north is not complete without a trip to Halong Bay, where placid waters give way to more than 3,000 limestone karsts and wind-sculpted limestone formations that jut from foggy lagoons. Dotting the bay are tiny islands bordered by white sandy coves and hidden caves, adding to the majestic landscape of this UNESCO World Heritage Site. Adding to this naturalist’s dream is the biodiversity of islets, grottos, and Cat Ba Island National Park. The bay, however, shows tourism’s impact: the clearing of mangrove forests to make way for jetties and piers, marine life threatened by game fishing, and garbage from passenger boats and fishing villages washed up on the shores.Beyond its geological uniqueness are activities like hiking, kayaking, rock climbing, or exploring one of the many floating villages where fishermen bring in their daily catch. The downside to all this allure is the large number of unlicensed boats it draws to the bay each day.Boat trips out onto the bay are the main tourism stock in trade farther north, but a more multifaceted side of the area can be experienced at Cat Ba Island. The largest island in Halong Bay, Cat Ba is very much its own entity. Its national park offers incredible biodiversity, with more than a thousand species of plants having been recorded here. Animal life is slightly thinner on the ground, but alert visitors may spy inhabitants such as the endangered golden-headed langur, wild boar, deer, civets, and several species of squirrel. Trekking through the wilderness is a highlight with a number of fascinating trails to follow.Cat Ba Island has also become a firm favorite with the adventure sports set. Indeed, along with Railay Beach in Thailand, it is recognized as one of the top spots in the region for rock climbing. Other outdoor pursuits include sailing and kayaking around the karsts. Although Halong Bay has arguably been tainted by over-exposure, Bai Tu Long Bay farther east toward China, retains all the majesty of Vietnam’s premier bucket-list natural attraction but sees a fraction of the traffic of its immediate neighbor to the west. Here, visitors will find islands of substantial size with deserted beaches and untamed jungle. Halong Bay's 3,000 islands of dolomite and limestone cover a 1,500-square-km (580-square-mile) area, extending across the Gulf of Tonkin nearly to the Chinese border. According to legend, this breathtaking land- and seascape was formed by a giant dragon that came barreling out of the mountains toward the ocean—hence the name (Halong translates into "descent of the dragon"). Geologists are more likely to attribute the formations to sedimentary limestone that formed here between 300 and 500 million years ago, in the Paleozoic Era. Over millions of years water receded and exposed the limestone to wind, rain, and tidal erosion.Today the limestone formations are exposed to hordes of tourists—but don't let that discourage you. Hundreds of fishing trawlers and tour boats share space on these crystal waters, yet there seems to be room for everyone. Most people use the main population center, Halong City, as a base from which to venture into the bay. Although it's now officially one municipality, Halong City was, until 1996, two separate towns: Bai Chay is now Halong City West, where Halong Road winds its way around the coast and past the lifeless central beach; Hon Gai is the grimier Halong City East, where a coal transportation depot dominates the center of town and covers nearby roads and buildings with a sooty film. Locals still refer to the towns by their old names, but they are now inexorably lassoed together by a bridge. Boat trips through Halong Bay are the main attraction. Little of the majesty of this region can be found in the city, so head out onto the water and start exploring. Countless 10- and 30-foot fishing boats have been converted into Halong Bay's formidable tourist-boat fleet. Hotels or travel agencies in Halong City or Hanoi can arrange boat trips for you (often they are part of organized tours from Hanoi). It is still possible to go down to the wharf and bargain yourself onto a boat for the day, but you are likely to be charged (sometimes significantly) more than you would pay for a prebooked tour, so this is not advised. Self-sufficient travelers have fallen victim to the old bait-and-switch: they've arranged a next-day boat tour with local fishermen, only to be told in no uncertain terms the following morning that they could not board their chosen boat, but they could take a different one for quite a bit more money. You may have no choice in the end. Usually travel agencies, however, have their tried-and-true favorites.

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.

With the glittering lights of Taipei - a futuristic metropolis of culture and ideas - sparkling nearby, Keelung is the first calling point for many visitors arriving in Taiwan. While this port city essentially serves as Taipei's ocean gateway, you shouldn’t be too hasty in dashing off to Taipei's neon-lit magic – first it’s well worth spending some time exploring the famous glowing night market, which hums with life each evening and is famous for its local seafood.

From Minami's neon-lighted Dotombori and historic Tenno-ji to the high-rise class and underground shopping labyrinths of Kita, Osaka is a city that pulses with its own unique rhythm. Though Osaka has no shortage of tourist sites, it is the city itself that is the greatest attraction. Home to some of Japan's best food, most unique fashions, and warmest locals, Osaka does not beg to be explored—it demands it. More than anywhere else in Japan, it rewards the impulsive turn down an interesting side street or the chat with a random stranger. People do not come here to see the city, they come to experience it.Excluded from the formal circles of power and aristocratic culture in 16th-century Edo (Tokyo), Osaka took advantage of its position as Japan's trading center, developing its own art forms such as Bunraku puppet theater and Rakugo comic storytelling. It was in Osaka that feudal Japan's famed Floating World—the dining, theater, and pleasure district—was at its strongest and most inventive. Wealthy merchants and common laborers alike squandered fortunes on culinary delights, turning Osaka into "Japan's Kitchen," a moniker the city still has today. Though the city suffered a blow when the Meiji government canceled all of the samurai class's outstanding debts to the merchants, it was quick to recover. At the turn of the 20th century, it had become Japan's largest and most prosperous city, a center of commerce and manufacturing.Today Osaka remains Japan's iconoclastic metropolis, refusing to fit Tokyo's norms and expectations. Unlike the hordes of Tokyo, Osakans are fiercely independent. As a contrast to the neon and concrete surroundings, the people of Osaka are known as Japan's friendliest and most outgoing. Ask someone on the street for directions in Tokyo and you are lucky to get so much as a glance. Ask someone in Osaka and you get a conversation.The main areas of the city, Kita (north) and Minami (south), are divided by two rivers: the Dojima-gawa and the Tosabori-gawa. Between Kita and Minami is Naka-no-shima, an island and the municipal center of Osaka. Kita (north of Chuo Dori) is Osaka's economic hub and contains Osaka's largest stations: JR Osaka and Hankyu Umeda. The area is crammed with shops, department stores, and restaurants. Nearby are a nightlife district, Kita-shinchi; Naka-no-shima and the Museum of Oriental Ceramics; Osaka-jo (Osaka Castle); and Osaka Koen (Osaka Park). Restaurants, bars, department stores, and boutiques attract Osaka's youth to Minami (south Chuo Dori); theatergoers head to the National Bunraku Theatre and electronics-lovers to Den Den Town. For a glimpse of old Osaka, visit Tenno-ji Temple and Shin Sekai. The main stations are Namba, Shin-sai-bashi, Namba Nankai, and Tenno-ji. There's easy access to the Municipal Museum of Fine Art and Sumiyoshi Taisha (Sumiyoshi Grand Shrine).The bay area, to the west of the city center, is home to the Osaka Aquarium and Universal Studios Japan. The Shinkansen stops at Shin-Osaka, three stops (about five minutes) north of Osaka Station on the Mido-suji subway line. To the north of Shin-Osaka is Senri Expo Park.
