Taveuni is a volcanic island that measures 434 km² (168 sq mi), making it the third-largest island in Fiji. Taveuni is part of the Vanua Levu group of islands.

The island is covered in lush vegetation and as a result, it is known as 'the Garden Island of Fiji'. Taveuni is popular for bush-walking and bird-watching. There are many scenic waterfalls on the island, as well as beautiful beaches that support excellent scuba-diving and snorkeling opportunities.
