Mulu Airport (IATA: MZV, ICAO: WBMU) is a small domestic airport serving the Mulu area in Sarawak, Malaysia, on the island of Borneo. It primarily exists to facilitate access to Gunung Mulu National Park, a UNESCO World Heritage Site renowned for its dramatic limestone karst formations, extensive cave systems, and rich biodiversity. The airport handles a modest volume of passenger traffic, mostly eco-tourists, researchers, and adventurers heading to the national park. Due to the remote jungle terrain, air travel is the most practical means of reaching Mulu, as road access is extremely limited or nonexistent. Maswings, a subsidiary of Malaysia Airlines focused on rural Sarawak routes, operates regular scheduled services connecting Mulu to Miri and other regional hubs, making it the lifeline for the local community and park visitors alike.
