Why visit Tonga
Tonga is a small country in Polynesia, with 747 km² of land and about 100,179 people. It suits travellers who want a slow, quiet trip with time by the sea, not a busy sightseeing list. English and Tongan are both spoken. The best months are June to September. The honest limitation is scale. Nukuʻalofa, the capital, has about 23,221 people, so there is little big-city nightlife or shopping.
