Pago Pago’s small size belies its historic stature and epic setting. The city—or more accurately, cluster of several fishing villages—lies along the shore of Pago Pago Harbor, which was carved from thousands of years of volcanic-crater erosion on Tutuila Island. The fjordlike harbor, one of the most stunning in the South Pacific, is bordered by steep and lush hills and dominated by Rainmaker Mountain. The protected harbor site was selected in 1872 by Commander R.W. Meade for a fuelling station for the U.S. Navy. Meade negotiated the real estate deal with a Samoan high chief and the resulting naval base at Pago Pago was in use from 1900 to 1951. Pago Pago itself is tranquil as far as capital cities go, though there is commerce and activity in the areas of Fagatogo and Utulei. The hills near the seafront are dotted with houses, while a variety of shops line the street that runs in front of the dock itself. The best views of the harbor and downtown can be had from the summit of Mount Alava in the National Park of American Samoa.

The remote Polynesian nation of Samoa, surrounded by dragonfly-bright seas, boasts a dramatic volcanic landscape with vibrant green jungles. The country has two major landmasses: Upolu, the most populous of the Samoan islands, and Savai'i, the third-largest Polynesian island. Samoa's capital, Apia, sits midway along Upolu's north coast. This sprawling metropolitan area features a waterfront promenade and Beach Road, an avenue curving along the harbor where the Royal Samoa Police Band marches and hoists the national flag at Government House on weekday mornings. Check out their sharp ensembles, which feature navy lavalava (kilts) and robin's-egg-blue dress shirts. Adventurers will want to make a splash at Palolo Deep National Marine Reserve near Apia harbor, while bookworms make a beeline to the home and grave of Robert Louis Stevenson. But perhaps the best way to experience fa'a Samoa (the Samoan Way) is by visiting the small villages scattered throughout the two islands. Here, you'll see locals still living in traditional fales—round thatched homes with no walls, all the better to enjoy the ocean breeze—and cooking on umus, "ovens" of hot stones placed in shallow holes in the ground.

Offering an alluring blend of nature and tranquility, the small island of Anatom (aka Aneityum) is one of the South Pacific's lesser-known but dependable tropical hotspots. The southernmost island of Vanuatu, its diminutive size (159 square kilometers, or 61 square miles) and lack of modern amenities—there's no Internet nor even running water or electricity—lends the place something of a Robinson Crusoe-esque atmosphere. Although it's possible to walk around the entire island in less than an hour, there is much to explore in a day trip. As well as taking advantage of the many soft, sandy beaches and the sparkling azure waters and coral reefs, it's possible to hike the many trails that crisscross the island's sandalwood-studded and mountainous interior. In addition, you can visit the village of Anelghowhat (or Anelcauhat) on the south side of the island, which has discarded whaling-industry equipment, former irrigation channels and the ruins of missionary John Geddie's church. It's also possible to visit picturesque Port Patrick, climb to the top of the extinct volcano Inrerow Atahein, or Inrerow Atamein (853 meters, or 2,800 feet), and admire various waterfalls dotted around the island, such as the impressive Inwan Leleghei. Off the shore of Anatom is the unpopulated Mystery Island, where cruise ship tenders moor and passengers get to spend some quality beach time on a deserted island paradise. Islanders from Anatom paddle out to meet the visitors and set up temporary shops near the dock, where they grill fish and sell a few snacks and souvenirs.

The East New Britain province of Papua New Guinea is lush and tropical. Mountain peaks and active volcanoes surround the town of Rabaul and Simpson Harbor. Built on an ancient volcanic crater, the harbor is one of the deepest in the region. For the same reason, some of most spectacular diving and snorkeling in the world can be found here. At Sub-Base, a shallow reef extends dramatically out from shore before dropping off into a crevasse rich with fish and other marine life. VIEW CRUISES

The sprawling town of Alotau, spectacularly located on Papua New Guinea’s southeastern tip, is an ideal introduction to the relaxed charms of the region. The capital of Milne Bay Province, Alotau is also the main port for the 600 islands that encompass the area. The buzzing harbor, just a short walk from town, is a hive of activity, with ships, boats and canoes transporting passengers and plying their trades.The town was the site of the 1942 Battle of Milne Bay, resulting in Japan's first defeat in the Pacific during World War II. Milne Bay was a major Allied base, and some of the war’s fiercest fighting took place in Papua New Guinea. Although there’s not much to see now, a fascinating Battle of Milne Bay tour combines historic war stories with locals’ tales of how modern warfare changed their world. More broadly, Alotau is an excellent place to gain insight into Papua New Guinea's cultures and traditions; don’t miss the Cultural Festival excursion in which you’ll see everything from warrior dances to gospel choirs to traditional drumming. For even more local flavor, wander through Alotau Market with its mounds of betel nuts, which many islanders chew.

Located in Papua New Guinea’s Milne Bay Province, Kiriwina is the largest of the Trobriand Islands and home to the majority of their 12,000-strong indigenous population. The picturesque island is steeped in history and is famous to many as a site of U.S. occupation during World War II. In fact, various relics of the war, including the remains of an American plane, can still be seen on the island. But Kiriwina is home to far more than history. Here, you’ll find an idyllic traditional lifestyle, incredibly friendly locals and a fascinating social structure that’s based on matrilineal clans, with unique marriage and courtship rituals. Many aspects of life revolve around the cultivation and exchange of yams.There’s also mesmerizing scenery, from crystal-clear waters to jungle-covered cliffs. Hire a dugout canoe, hike to the burial caves, peruse exquisite carvings and explore the coral-filled offshore islands. Be sure to stop and watch a game of Trobriand cricket, an innovative spin on the game. Whatever you choose to do, it’s bound to be an eye-opening experience.

Papua New Guinea is quickly becoming a favorite destination for cruise passengers, and it’s easy to see why when you visit the Conflict Islands. Although the name might not sound inviting (don’t worry, they're named after a British naval ship, not a war), these 21 islands are like paradise on earth: Tropical islets encircle an enormous turquoise lagoon formed by the rim of a sunken volcano, with vibrant coral reefs and rainbow schools of fish below the water. Located about 160 kilometers (97 miles) east of Papua New Guinea in the Coral Sea, the island group is owned by Australian businessman and conservationist Ian Gowrie-Smith, who is dedicated to protecting the ecosystem of the islands (he has an eco-resort on one island; the rest are uninhabited).Just as Papua New Guinea is one of the wildest and most diverse places on the planet, the seas here offer some of the world’s most extensive biodiversity and coral reefs, making for unparalleled kayaking, diving and snorkeling. There are hundreds of coral species and thousands of species of fish and invertebrates such as the sea cucumber. If you ever get bored with watching manta rays float past, lie back on the white sand, look up at the palm trees blowing in warm trade winds or watch the sun set over the lagoon, and dream of owning your own chain of tropical islands.

A friendly city loved by residents and popular with tourists. More than just a gateway to the Great Barrier Reef, Cairns offers plenty to do.

The Great Barrier Reef is made of many types of reefs, from offshore bommies that rise from the depths like undersea skyscrapers, to atolls where rings of coral surround placid lagoons. The Ribbon Reefs are another unique formation—long, narrow ridges of coral running parallel to the shore. They act like breakwaters, providing calm seas on their western sides, facing the Australian mainland. The Ribbon Reefs run for around 50 miles (80 kilometers), with a total of 10 ribbon reefs named by number, from south to north. Remote Lizard Island marks the northern reaches of this section of the Great Barrier Reef—the final landmark before sailing on to the Cape York Peninsula and the Torres Strait. The greatest highlights of the Ribbon Reefs are found below the water, where divers and snorkelers can explore undersea gardens bursting with corals, tropical fish, sharks and much more. Topside explorers should keep watch from the ship for dolphins and whales, especially during the months of June and July, when dwarf minke whales arrive from Antarctica to birth their young.
