How to Get to Kao (island) #
Kao is in the Haʻapai island group and has no regular public transport. The usual route is to fly from Nukuʻalofa (Fuaʻamotu Airport) to Lifuka (Haʻapai) on domestic services (Real Tonga) and then arrange a private boat or charter from Lifuka/Pangai to Kao - there are no scheduled ferries. Landing requires local coordination with boat operators from Lifuka; expect a multi-hour sea crossing depending on vessel.
Tips for Visiting Kao (island) #
- Plan visits during Tonga's dry season (May-October) and aim for an early-morning boat from Lifuka/Pangai when seas are calm and the climb is coolest.
- Arrange access through a local operator and obtain landowner permission in advance - Kao is uninhabited and organized trips handle boats, guides and safety briefings.
- Most visitors focus on the summit; if your boat operator offers it, ask to circumnavigate sections of the coastline to see dramatic sea cliffs and volcanic features that aren't visible from the trail.
