La Mina Airport is a small general aviation airstrip located near El Guabo, a canton in El Oro Province in southern coastal Ecuador. The facility primarily serves light aircraft operations and provides limited regional air access to an area known for banana cultivation and agricultural activity. The airport holds the ICAO designator SEIN and does not have an assigned IATA code, reflecting its status as a minor, non-commercial facility. Scheduled commercial airline service is not operated from this airstrip, and it functions mainly to support private and utility flights in the region.
