Mount Kinabalu is a prominent mountain in Southeast Asia. It is located in Kinabalu National Park in the east Malaysian state of Sabah, which is on the island of Borneo in the tropics. It is the tallest mountain in the Malay Archipelago.

In 1997, a re-survey using satellite technology established its summit height at 4,095 metres above sea level, which is some 6 metresless than the previously thought and hitherto published figure of 4,101 metres

The mountain and its surroundings are among the most important biological sites in the world,with over 600 species of ferns, 326 species of birds, and 100 mammalian species identified. Among them are the gigantic Rafflesia plants and the orangutan. Mount Kinabalu has been accorded UNESCO World Heritage status.

The main peak of the mountain can be climbed easily by a person with a good physical condition, and requires no mountaineering equipment. Other peaks along the massif, however, require rock climbing skills.
