Fiji has an unspoiled, unique environment of extreme beauty and tranquillity. There are six national parks. Trails into the rainforest often pass through local villages and combine the stunning natural scenery with ecotourism. Adrift for millennia in splendid isolation in the blue of the South Pacific Fiji has largely escaped industrial progress, the incursions of dangerous animals, poisonous snakes, spiders and pestilent diseases such as malaria. In July 1989, the Sigatoka Sand Dunes were designated as Fiji's first National Park. The Dunes are a unique feature, and form an area of outstanding natural beauty covering 650 hectares, offering a rich combination of interesting features.
