Kayan Mentarang National Park

Kayan Mentarang National Park spans approximately 13,605 square kilometers across the Indonesian provinces of North and East Kalimantan on Borneo Island. The park encompasses rugged mountainous terrains, dense tropical rainforests, and river systems that form the upper reaches of the Kayan and Mentarang rivers. This landscape supports one of the richest biodiverse ecosystems in the world, with numerous endemic species, including orangutans, clouded leopards, proboscis monkeys, hornbills, and diverse flora such as dipterocarp trees and orchids. The park is also culturally significant, home to several indigenous Dayak communities who maintain traditional lifestyles and sustainable land-use practices. Visitors can explore Kayan Mentarang through multi-day jungle treks, river expeditions, and cultural visits to local villages. The park offers challenging trekking routes combined with opportunities for wildlife spotting and experiencing remote rainforest environments. Due to its remote location and rugged terrain, the park attracts adventurous travelers and researchers interested in tropical ecology and indigenous cultures. Its protected status helps safeguard critical habitats amid pressures from logging and palm oil plantations elsewhere on Borneo. With extensive biodiversity, diverse landscapes, and cultural heritage, Kayan Mentarang National Park remains a vital conservation area and a captivating outdoor destination in Indonesia.
