Meratus Mountains at a Glance

About Meratus Mountains

The Meratus Mountains are a forested mountain range in southeastern Borneo, located primarily within Indonesia’s South Kalimantan province. The range is an important ecological area and a traditional homeland of the Meratus Dayak people.

The landscape consists of rugged ridges, narrow valleys and river systems with extensive tropical rainforest cover. Opportunities are mainly for trekking, river travel and visiting traditional Dayak settlements; infrastructure for mass tourism is limited.

Local Dayak groups have inhabited the range for centuries and maintain customary land uses such as shifting cultivation and forest resource management. In recent decades the area has faced pressure from logging and agricultural expansion, but many interior valleys remain relatively remote.

The range runs inland from the southeastern coast of Borneo in South Kalimantan province. The nearest major urban center for access and services is Banjarmasin on the southeast coast of Kalimantan.

  • Cultural and ecological significance: Home to indigenous Meratus Dayak communities and high biodiversity, with steep forested ridges and river valleys that support tropical rainforest species.
  • Access and logistics: Access is limited and often requires local guides; the nearest major city for logistics is Banjarmasin in South Kalimantan.
