Tongatapu.Tongatapu is Tonga's largest island with over two-thirds of the country's small population. It is a coral island surrounded by coral reefs. The capital, Nuku'alofa, on the north coast, has a relaxed air, despite the troubles of a few years ago. There are some interesting places to visit, such as ancient tombs and coastal blowholes, and some nice beaches with good snorkelling. Tongatapu also provides a good opportunity to view a unique culture. There are several small islands to the north of Tongatapu that have been developed into resorts. Nuku'alofa has good quality accommodation as well as guest houses within range of the backpacker.

It has beaches on the western side but dramatic cliffs on the east coast, with Tongaâs largest tropical rain forest, which is a great place to go trekking. There are a few small guest houses.
