About Manus Island
Manus Island is the largest island in the Admiralty Islands archipelago and is the administrative centre of Manus Province in northern Papua New Guinea. The island’s main town and port is Lorengau.
The island and surrounding isles played a strategic role during the Pacific campaign of World War II and contain military sites and wartime remains. Manus is also a centre for local fisheries, small‑scale agriculture and inter‑island transport within the archipelago.

Tips for Visiting Manus Island
- Access to Manus Island is limited and mostly through Lorengau; air services are infrequent, so book flights and any onward boat transfers well in advance and confirm schedules before travel.
- Check current travel advisories and entry requirements for Papua New Guinea and obtain any necessary permits-Manus has remote communities and differing local regulations, and security conditions can change.
- Arrange a local guide or contact a host before arrival: road and coastal transport infrastructure is basic, and guided local knowledge is essential for reaching villages and safe coastal sites.
