Private Caldera Bay Boat Expedition: Into the Volcano's Heart

Drift by private tender into the submerged caldera of an ancient volcano — one of the most dramatic and rarely visited seascapes on Earth. Sheer green walls plunge into electric-blue water in a natural amphitheatre accessible only by sea.

What to expect

Board a chartered private tender and glide into Garove's submerged volcanic caldera, the glassy bay enclosed by jungle-draped walls rising hundreds of metres. Your naturalist guide narrates the island's volcanic geology and Bismarck Sea ecology as you explore. The boat pauses at prime vantage points for photography and swimming from the hull. Pristine isolation — no crowds, no schedules — defines the experience.
