More of a large town than a city, Darwin is less about what’s contained within the city limits and more about the huge expanse of wild landscape that’s outside it. Closer to Jakarta than Sydney, the city really does feel remote in its tropical perch.

The protected marine reserve of Triton Bay rivals Raja Ampat as one of Indonesia’s premier locations for snorkelling and scuba diving. The biodiversity here is remarkable, with species ranging from pygmy seahorses to mighty whale sharks, and it’s also a nesting site for green turtles.

Misool is one of the main islands in the Raja Ampat archipelago, surrounded by some of the most spectacular coral reefs on earth. Snorkel, swim and kayak amongst these rich, biodiverse waters, and explore white sandy beaches, mangroves, lakes and jungle-clad limestone peaks.

Sparsely populated and spectacularly beautiful, the Raja Ampat archipelago is a treasure trove of jungle-smothered islands, white sand beaches and some of the best diving in the world. The crystal clear waters are teeming with tropical fish, while on land you can see parrots, hornbills and birds of paradise.

Madang, first settled by Germans during the 19th century, was once known as the ‘prettiest town in the Pacific’, and retains its charm despite significant damage during the Second World War. There is some great snorkelling and diving just offshore, while the city’s towering casuarina trees support a noisy population of flying foxes.

Garove is a flooded volcanic caldera, with most of the inhabitants living on the outside of the volcano, and just one village inside the steep-sided caldera itself. Visiting ships are met by curious locals in outrigger canoes, and you may be welcomed ashore with a traditional ‘sing-sing’.

Looming over Rabaul is smouldering Mount Tavurvur, an active volcano that buried much of the city when it erupted in 1994, and which still periodically belches smoke and ash. Rabaul is also an appealing destination for history buffs, with several World War II sites still scattered with rusting wreckage.

The lush island of Santa Ana, also known as Owaraha, is home to just three villages, and visitors are usually welcomed to the island with traditional songs and dances. You will find a few stalls where you can buy locally-made souvenirs, and you can also snorkel in the surrounding lagoon.

Champagne Beach is a stunning stretch of perfect white sand on the east coast of Espiritu Santo, the largest of Vanuatu’s islands. The beach is named after a bizarre natural phenomenon, in which gas escaping from volcanic rocks on the sea floor causes the water to bubble and fizz at low tide.

Ambrym is known as the ‘Black Island’ due to its dark volcanic soil, with two active volcanoes, Mount Marum and Mount Benbow. The island is also known for its magic and sorcery, and for its traditional Rom dances, when locals don elaborate masks and costumes.

Lautoka is Fiji’s second largest city, known as the ‘Sugar City’ due to its important role in the local sugarcane industry. The waterfront area is pleasant enough, but we’d recommend using Lautoka as a jumping off point to visit some of the smaller surrounding islands, or the forests and waterfalls of the interior.
