Fergusson Island
Volcanic landscapes and coastal communities make Fergusson a distinctive stop in the D’Entrecasteaux Islands. The Deidei geothermal area is a notable locally hosted visitor experience.
Where heat rises through the landscape.
Expedition accounts describe Deidei’s geothermal pools, mud pools and steam vents, along with demonstrations hosted by local villagers. These are active thermal features within a lived cultural landscape.
Arrange a visit through local hosts who can explain both the place and its protocols. Stay on the route they indicate, keep away from hot water and unstable edges, and never treat the pools as unsupervised bathing sites.

Planning your visit
Confirm a host, landing arrangement and guide before departure. Conditions on shore and at sea can change the plan.
A locally hosted experience
Ask the appropriate hosts which places and activities they are comfortable sharing. Confirm fees, photography permission, transport and a return plan before setting out. Buy directly from local makers where possible and carry waste away.
