Riam Batu Airstrip is a small, remote aviation facility located in Riam Batu, within the Indonesian portion of Borneo (Kalimantan). It serves as a basic point of access for communities in a region characterized by dense jungle and limited road infrastructure. The airstrip operates primarily to support local connectivity, humanitarian missions, and light general aviation traffic. Such facilities in interior Kalimantan are often served by small propeller aircraft operated by regional carriers or missionary aviation organizations. Detailed operational and infrastructure information about this airstrip is limited in publicly available sources, reflecting its small scale and remote character.
