Divisions of Tonga Map

Tonga, a Polynesian country, comprises over 170 islands in the South Pacific Ocean. Its maritime boundaries include established and provisional borders with neighboring states: an official boundary with Fiji, and provisional boundaries with Niue, Samoa, and the United States of America. Additionally, Tonga has a gazetted and enforced treaty with France concerning Wallis and Futuna, which was established on 11 January 1980. The total area of Tonga is approximately 650 km2 (251 mi2).

The waters around Tonga are known for their deep-sea trenches, including the Tonga Trench, one of the deepest parts of the ocean. The lowest point in Tonga is the Pacific Ocean's surface, at sea level. Elsewise, the Tongan archipelago is divided into three main geographical regions: Tongatapu, Haʻapai, and Vavaʻu. Tongatapu, the southernmost group of islands, is the most populous and hosts the country's capital, Nuku'alofa. It features flat terrain with limestone and coral formations. The highest point in this region, and also in Tonga, is an unnamed location on Kao Island in the Haʻapai group, reaching 1,030 meters (3,379 feet) above sea level.

Haʻapai, located north of Tongatapu, consists of a series of islands and islets, characterized by coral reefs and sand banks. The topography is generally low-lying, with a few volcanic islands like Tofua. This region's significant bodies of water include lagoons and coral reefs that are important for marine life and local navigation.

The Vavaʻu group to the north of Haʻapai is known for its hilly terrain, sheltered bays, and deepwater harbor. The region's geography makes it a popular destination for yachting and whale watching. The islands here are formed from volcanic activity, with lush, fertile soils supporting diverse vegetation.
