Koulamoutou Mabimbi Airport (IATA: KOU, ICAO: FOGK) is a domestic airport serving the town of Koulamoutou, the capital of Gabon's Ogooué-Lolo Province. It provides an essential air link for a region where road infrastructure is limited and travel overland can be lengthy and difficult. The airport handles light domestic traffic, primarily connecting Koulamoutou with Libreville, Gabon's capital. It plays an important role in supporting local administration, commerce, and access to remote communities in the surrounding rainforest region. Facilities are modest, reflecting the airport's role as a small regional hub rather than an international gateway. Passenger volumes remain low, and operations are straightforward with minimal infrastructure compared to larger Gabonese airports.
