Cruises from Ambrym Island

Ambrym is an island in the archipelago of Vanuatu (formerly known as the New Hebrides) in the South Pacific. It remains volcanically active, with two volcanic cones Benbow and Marum that still rumble away, and smaller vents and fractures that ooze steam and lava. The centre of the island is dominated by a massive 1900 year old 12 km diameter desert-like caldera that hosts multiple craters. The rest of the caldera floor is a barren ash plain, caused by the natural acidic rain.
