The Tunku Abdul Rahman National Park comprises a group of 5 islands located between 3 to 8 km off Kota Kinabalu in Sabah, Malaysia. The park is spread over 4,929 hectares, two-thirds of which cover the sea. Before the Ice age, it formed part of the Crocker Range mass of sandstone and sedimentary rock on the mainland. However, about one million years ago, the melting ice brought about changes in the sea level and parts of the mainland were cut off by the sea to form the islands of Gaya, Sapi, Manukan, Mamutik dan Sulug. Evidence of this can be seen from the exposed sandstone of the coastline forming the cliffs, caves, honeycombs and deep crevices. The park was named after Tunku Abdul Rahman, Malaysia's first Prime Minister.
