Mount Kinabalu is 4095 m high. It is situated in the Borneo's Crocker Range. Mount Kinabalu consists mainly of granodiorite, an igneous rock similar to granite. First men to reach the top of Mount Kinabalu were Hugh Low and Spenser St. John in 1858. The climb to the top of the Mount Kinabalu can start from two places – from Timpohon Gate or Mesilau Nature Resort. The climb to the top takes approximately 2 to 4 hours, although there is no need to have a climbing gear, a guide is acquired by park regulations. Since the peak is in a high altitude climbers can be affected by altitude sickness. The Mount Kinabalu is part of the national park Kinabalu , which is famous for its enormous enormous biological diversity - one can see there a number of endemic plants and animals including rare orchids or orang-utans.
