Buen Retiro Ballivian Airport (ICAO: SLBT) is a small general aviation airstrip located in the Ballivian municipality of Bolivia. It serves as a basic point of air access for a remote area where road infrastructure is limited, making air transport an important link for local communities. The airport operates at a minimal scale, primarily handling light aircraft and small charter or mission flights. It does not support scheduled commercial airline services and has no significant passenger terminal infrastructure.
