Tonga Country in Oceania information and photo #Tonga – Tonga flag, maps, people, coloring pages and more. Tonga is a Polynesian kingdom of more than 170 islands, many uninhabited, most lined in white beaches and coral reefs and covered with tropical rainforest. The main island, Tongatapu, is protected by lagoons and limestone cliffs. It’s home to the laid-back, rural capital of Nuku’alofa, as well as beach resorts, plantations and the Ha’amonga trilithon, a Stonehenge-like coral gate from the 1200s.
