Greenville/Sinoe Airport — Greenville, Liberia

Greenville/Sinoe Airport, coded SNI, serves Greenville, the capital of Sinoe County in southeastern Liberia along the country's Atlantic coastline. The airstrip provides essential air connectivity for a region where road infrastructure remains underdeveloped, particularly during Liberia's heavy rainy seasons when overland travel becomes difficult or impossible. Sinoe County's economy centers on agriculture, timber, and fishing, and SNI supports the movement of officials, aid workers, and occasional travelers between this remote coastal county and the capital, Monrovia. As with much of Liberia's aviation infrastructure, the airport reflects a post-conflict nation still rebuilding transport networks, making air links like SNI disproportionately important for connecting isolated coastal communities to national administrative and commercial centers.
