The Ha’apai Group in the middle of the kingdom consists of numerous small, atoll-like islands scattered across the sea. Of the 62 islands in the Ha'apai group, only 17 are inhabited. On those 17 islands, there are approximately 8,000 people settled in 30 villages. Linked by a causeway, Lifuka and Foa are the largest and the only ones you can visit without being on a yacht.
