The major island groups are Tongatapu and 'Eua, Ha'apai and Vava'u. Tonga's high volcanic and low coral forms give the islands a unique character. Sightseeing on Tongatapu should include the Royal Palace on the waterfront in Nuku'alofa. The grounds are decorated with tropical shrubs and flowers.
Nightlife is sedate, limited to music and dancing in the hotels.
Tongan feasts and entertainment are also organised. At 13 hours ahead of GMT, Tonga will be the first country to meet the new millennium and a National Millennium Committee is coordinating plans for special events for the year 2000.
