Tonga

Tonga is an island country in the South Pacific, made up of more than 170 islands spread across several groups. Its western islands are volcanic and rise sharply from the sea, while many eastern islands are lower and formed from coral limestone. Tongatapu is edged by reefs and lagoons, and the Vavaʻu and Haʻapai groups contain sheltered channels, small islands, and long stretches of coastline.
