In the 19th century, Spenser St. John and Charles Hose, attempted to conquer Mount Mulu.

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 Lord Shackleton and an Oxford University Expedition to the summit of Mount Mulu.
