Tunku Abdul Rahman National Park comprises a group of 5 islands located between 3 to 8 km off Kota Kinabalu. 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 Pulau Gaya, Pulau Sapi, Pulau Manukan, Pulau Mamutik dan Pulau 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.Jesselton Point Ferry Terminal in downtown Kota Kinabalu is the ferry terminal for those heading to the islands in Tunku Abdul Rahman National Park (Pulau Gaya, Pulau Sapi, Pulau Manukan, Pulau Mamutik dan Pulau Sulug). This ferry terminal is also the departure point for patrons staying at either Manukan Island Resort or Gayana Resort.
