Muara Wahau Airport, designated by ICAO code WALW, is a small regional airstrip located near Miau Baru in the Kutai Timur Regency of East Kalimantan, Indonesia. It serves as a vital air access point for communities in a region characterized by dense tropical forest and limited road infrastructure. The airport primarily supports light charter and general aviation flights, connecting the area to larger urban centers in Kalimantan. Its role is especially important for residents and workers in the surrounding mining and forestry industries who would otherwise face long overland journeys. Given its remote location, the facility is modest in scale with basic infrastructure suited to small propeller-driven aircraft. It does not currently hold an IATA code, reflecting its limited role in scheduled commercial aviation.
