Sege Airport is a small domestic airstrip located in the Western Province of the Solomon Islands, serving the community of Sege near the famous Marovo Lagoon, a UNESCO-listed biosphere reserve. The airport provides a vital air link for local residents and tourists visiting one of the world's largest saltwater lagoons. The airstrip handles light aircraft and small propeller-driven planes, typical of the domestic aviation network across the Solomon Islands. It plays an important role in connecting remote island communities to the provincial capital Gizo and the national capital Honiara, where road and sea access can be limited or time-consuming.
