In the 19th century, Charles Hose (an administrator in the Raj of Sarawak), attempted to climb Mount Mulu but failed. It was only in the 1920s, when a Berawan rhino hunter named Tama Nilong discovered the south-west ridge near the mountain which eventually led to the summit. In 1932, Tama Nilong led Edward Shackleton during an Oxford University Expedition to the summit of Mount Mulu.[4] This is the first successful ascend to the summit of Mount Mulu.[2] In 1961, G.E. Wilford, of the British Borneo Geological Survey visited Mulu caves.
