Vailala Airstrip (ICAO: AYVA) is a small, remote airstrip located near Hepa in the Gulf Province of Papua New Guinea. It serves as a vital access point for communities along the Vailala River, a region largely inaccessible by road. The airstrip supports light aircraft operations, primarily serving missionary, aid, and cargo flights that connect isolated villages to larger centers. It is typical of the numerous small bush airstrips found throughout Papua New Guinea that provide essential links to remote populations. Operations are minimal and the facility lacks significant infrastructure, functioning mainly as a grass or unpaved strip suited to small single or twin-engine aircraft.
