The park has no significant history of human settlement. However, small settlements have grown up along the trekking route to Sandakphu and Phalut. There is a reasonably large village at Kala Pokhri, around the lake of the same name. The Singalila Ridge was used as an approach route by the first documented mountaineering team which unsuccessfully attempted to climb Kanchenjunga in 1905. The team was led by Jules Jacot-Guillarmod and the famous occultist Aleister Crowley.
