Tourism, particularly eco-tourism, is a major contributor to the economy of Sabah. In 2006, 2,000,000 tourists visited Sabah[27] and it is estimated that the number will continue to rise following vigorous promotional activities by the state and national tourism boards and also increased stability and security in the region. Sabah currently has six national parks. One of these, the Kinabalu National Park, was designated as a World Heritage Site in 2000.
