Vava’u is a group of more than 50 islands in Tonga, about 150 miles north of Tongatapu. They are either raised coral limestone or coral atolls. The beautiful harbour opposite the main town of Neiafu (known as the Port of Refuge Harbour) is a common destination for yachties sailing the South Pacific. The waters of the islands are known for their clarity, it being said that you can see the bottom at 40 metres. The area attracts many humpback whales between June and November and there are lots of companies organising tours to see them. There are numerous places to stay, to suit most budgets.
