Pozo Brujo Airport (ICAO: SCZB) is a small general aviation airstrip located near La Unión, a city in the Los Lagos Region of southern Chile. It serves primarily private and light aircraft operations, providing basic air access to an area otherwise reliant on road transport. La Unión is situated in the Ranco Province, a largely agricultural and rural region, and the airport reflects the modest aviation infrastructure typical of smaller Chilean localities. It does not handle scheduled commercial airline services.
