Binaka Airport — Gunungsitoli, Indonesia

GNS is Binaka Airport, serving Gunungsitoli, the main town on Nias Island off the western coast of Sumatra, Indonesia. Nias is known for its distinctive traditional stone-jumping culture, surf tourism, and its history of major seismic activity, having been struck by devastating earthquakes and tsunamis in the past. GNS provides a critical air link connecting the island to Sumatra's mainland cities like Medan, supporting both everyday travel for residents and the surf and cultural tourism that draws visitors from around the world. Given the island's earthquake risk, the airport also plays a role in disaster response logistics when needed. Domestic carriers operate regular flights here, making GNS the primary aviation gateway for the entire island of Nias.
