28-Day Legendary Coral Triangle & Great Barrier Reef

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.

The Spanish arrived at this beautiful corner of the world in March of 1872, founding the city, that would eventually become the Capital of Palawan. In 2011, the area received a huge boost, when New7 announced its list of the 7 Wonders of Nature – counting 500 million votes in the process. Puerto Princesa’s stunning underground river - complete with a cavernous, sunken lagoon - beat off wonderful sites like the Great Barrier Reef, to claim a spot on the final, prestigious list. Set sail across the glowing green water, on a journey into the gaping mouth of the limestone caves at Puerto Princesa. Known for being one of the least densely populated, cleanest and most environmentally friendly cities in the Philippines, there’s a raft of natural wonders to explore - from diving hotspots to towering limestone cliffs, and the entrancing underworld of the underground river.

Rabaul, the former provincial capital, has quite a remarkable location. The town is inside the flooded caldera of a giant volcano and several sub-vents are still quite active today! The fumes of the volcano Tavurvur can be seen continually and the town suffered greatly during the last major eruption of 1994 when some 80% of the houses collapsed due to the ash raining down onto their roofs. Rabaul has a Volcano Observatory sitting atop the town’s center, monitoring the 14 active and 23 dormant volcanoes in Papua New Guinea. A small museum opposite the bunker used by Yamamoto during World War II shows exhibits relating to Rabaul’s local, German, Australian and Japanese past from the 19th century to Papua New Guinea’s independence in the 1970s.

This coastal city has little in the way of sandy beaches or surf, but it does have shady parks, charming colonial buildings, and a boardwalk-flanked waterfront Esplanade with a terrific man-made beach and picnic facilities. The historic town center has thrived recently, with an influx of lively eateries and bars. There are also some excellent museum and a world-class aquarium.Queensland Parks and Wildlife Service has an office on Magnetic Island, but Townsville Enterprise's information kiosks in Flinders Square and the Museum of Tropical Queensland (MTQ), on the mainland, are the best sources of visitor info about the island.

Tourism is the lifeblood of Cairns (pronounced Caans). The city makes a good base for exploring the wild top half of Queensland, and tens of thousands of international travelers use it as a jumping-off point for activities such as scuba diving and snorkeling trips to the Barrier Reef, as well as boating, fishing, parasailing, scenic flights, and rain-forest treks.It's a tough environment, with intense heat and fierce wildlife. Along with wallabies and grey kangaroos in the savannah and tree kangaroos in the rain forest, you'll find stealthy saltwater crocodiles, venomous snakes, and jellyfish so deadly they put the region’s stunning beaches off- limits to swimmers for nearly half the year. Yet despite this formidable setting, Cairns and tropical North Queensland are far from intimidating places. The people are warm and friendly, the sights spectacular, and—at the right time of year—the beachside lounging is world-class.

Darwin is Australia's most colorful, and exotic, capital city. Surrounded on three sides by the turquoise waters of the Timor Sea, the streets are lined with tropical flowers and trees. Warm and dry in winter, hot and steamy in summer, it's a relaxed and casual place, as well as a beguiling blend of tropical frontier outpost and Outback hardiness. Thanks to its close proximity to Southeast Asia and its multicultural population it also seems more like Asia than the rest of Australia. Darwin is a city that has always had to fight for its survival. The seductiveness of contemporary Darwin lifestyles belies a history of failed attempts that date from 1824 when Europeans attempted to establish an enclave in this harsh, unyielding climate. The original 1869 settlement, called Palmerston, was built on a parcel of mangrove wetlands and scrub forest that had changed little in 15 million years. It was not until 1911, after it had already weathered the disastrous cyclones of 1878, 1882, and 1897, that the town was named after the scientist who had visited Australia's shores aboard the Beagle in 1839. During World War II it was bombed more than 60 times, as the harbor full of warships was a prime target for the Japanese war planes. Then, on the night of Christmas Eve 1974, the city was almost completely destroyed by Cyclone Tracy, Australia’s greatest natural disaster. It's a tribute to those who stayed and to those who have come to live here after Tracy that the rebuilt city now thrives as an administrative and commercial center for northern Australia. Old Darwin has been replaced by something of an edifice complex—such buildings as Parliament House and the Supreme Court all seem very grand for such a small city, especially one that prides itself on its casual, outdoor-centric lifestyle. Today Darwin is the best place from which to explore Australia's Top End, with its wonders of Kakadu and the Kimberley region.

Pink Beach earned its name for the way the beach can appear to have a rosy hue in certain lights. The color comes from small flecks of red coral mixed in with the fine white reef sand. With a few trees along the beach for shade, this stretch of coast makes a fine place to relax or enjoy a snorkel or dive in the crystal clear waters. It is possible to spot a striped clown fish nestled among the protective tentacles of its sea anemone host, or to see a grouper lazily swimming by a flamboyant soft coral. The reef here is now protected by law and the maturing corals are a joy to behold.

Bali really is as alluring as everyone says. This island, slightly bigger than Delaware, has it all: beaches, volcanoes, terraced rice fields, forests, renowned resorts, surfing, golf, and world-class dive sites. But what sets Bali apart from other nearby tropical destinations is Balinese tradition, and villagers dedicated to celebrating it. The hundreds of temples, dances, rituals, and crafts linked to their ancient Hindu faith aren't a show for tourists, but a living, breathing culture in which visitors are warmly received by the Balinese, who cherish their own identities.
