Vava'u

Vava'u, Tonga — a scattered archipelago of over 50 islands around a sheltered natural harbor, the South Pacific's best-known sailing and yacht-charter base.

Charter a yacht or join a day-sail from Neiafu to island-hop between hidden anchorages, swimming caves like Mariner's Cave (accessed by an underwater passage), and uninhabited motu with white-sand beaches. Vava'u is also a prime humpback whale nursery from July to October, alongside Tonga's Ha'apai group.
