Papua New Guinea
Garove Island emerges from the Bismarck Sea like a vast natural amphitheater — a flooded volcanic caldera whose breached rim creates one of the most dramatic anchorages in the Pacific. The island, part of the Witu group in New Britain Province, Papua New Guinea, is essentially the remains of a collapsed volcano: a ring of steep, jungle-clad ridges surrounding a deep central lagoon that opens to the sea through a gap in the southwestern wall. Ships entering through this breach find themselves in a sheltered basin of extraordinary beauty, surrounded on three sides by emerald-green walls rising hundreds of meters from the waterline.
The caldera lagoon is deep — over 100 meters in places — and its waters range from cobalt blue in the center to turquoise shallows along the inner shores. Small villages dot the caldera rim, their stilt houses and gardens clinging to the steep slopes with the tenacious ingenuity characteristic of Melanesian settlement. The villagers are subsistence farmers and fishermen, growing taro, sweet potato, and coconut on the fertile volcanic soil while fishing the lagoon's abundant waters. Traditional outrigger canoes, still carved from single tree trunks, are the primary means of transport between communities.
The marine environment within and around the caldera is exceptional. The sheltered lagoon supports healthy coral gardens along its shallower margins, while the outer reef — particularly along the caldera's intact northern and eastern walls — drops away into deep water teeming with pelagic species. Snorkeling from the beach reveals colorful reef fish, sea cucumbers, and occasional sea turtles. The waters around Garove are also known for sightings of spinner dolphins and pilot whales, which use the deep channel between the Witu Islands as a migration corridor.
Cultural encounters on Garove are among the most authentic available in Papua New Guinea's cruise circuit. The island's communities maintain traditional customs including elaborate sing-sing performances — ceremonial dances featuring body paint, feathered headdresses, and kundu drum music that express clan identity and spiritual connection to the land. Village visits arranged through expedition cruise ships typically include welcome ceremonies, handicraft displays, and the opportunity to walk through gardens where villagers explain traditional agricultural practices.
Expedition cruise ships enter the caldera through the southwestern breach and anchor in the lagoon — one of the most memorable anchorage experiences available to any cruise passenger anywhere. Zodiac landings on the caldera's inner beaches bring passengers ashore for village visits and nature walks. There are no tourist facilities, shops, or infrastructure. The best visiting season is May through October, when the southeast trade winds bring the driest weather. Malaria prophylaxis is essential. Garove is not a destination you visit for comfort — it is a destination you visit to understand what it feels like when a volcano, a coral reef, and a human community achieve a balance so perfect it seems orchestrated.
