The Mamanuca Islands of Fiji are a volcanic archipelago lying to the west of Nadi and to the south of the Yasawa Islands. The group, a popular tourist destination, consists of about 20 islands, but about seven of these are covered by the Pacific Ocean at high tide. The Mamanuca Islands, just off the coast of Denarau offer crystal clear waters, palm fringed sandy beaches and live coral reefs. There are islands, villages, great resorts to visit, snorkelling and swimming. One of the islands, Monuriki, was the main location for the 2000 film Cast Away
