The Pulau Tiga Marine National Park achieved worldwide fame as 'Survivor Island' because of the popular Million Dollar Prize Money TV series 'Survivor' by the CBS TV network, USA. This is the island that the entire first series was filmed! The fact that this island was chosen was due to its untouched natural landscape and marine life.

The Pulau Tiga Park covers an area of 15,864 ha and was gazetted as a National Park in 1978. As far back as 1933, the main island, together with the two smaller islands of Kalampunian Besar and Kalampunian Damit were designated as Forest Reserve

There are two more islands in the Pulau Tiga Park, approximately 20 minutes by boat to the north of the main island, Pulau Tiga. They are very different. Kalmpunian Besar is a small sand cay built up from unconsolidated coral fragments, and the shape of the island shifts and changes with the prevailing monsoon winds and currents. Kalampunian Damit (also known as "Snake Island") is celebrated as a breeding ground for the amphibious sea snake Laticauda colubrina, which comes to the shores to lay eggs. The snakes can usually be seen coiled in a tangled mass under boulders or among tree roots.
