Borneo is the island home to Mount Kinabalu, Malaysia’s highest mountain.
Mount Kinabalu rises in Sabah, a Malaysian state on Borneo’s northern coast, and reaches 4,095 metres above sea level. The mountain is the centrepiece of Kinabalu Park, a UNESCO World Heritage Site known for exceptional plant diversity.
Borneo is the world’s third-largest island and is politically divided among Indonesia, Malaysia, and Brunei. Indonesia controls most of its area, where the island is known as Kalimantan; Malaysia occupies Sabah and Sarawak, while Brunei lies on the north coast.
Mount Kinabalu is not in Indonesia’s mountain ranges on Java or Sumatra, a common geographic mix-up. Its granite summit and surrounding Crocker Range make it one of Southeast Asia’s best-known highland landmarks.
