El Trompillo Airport (IATA: SRZ, ICAO: SLET) is a domestic airport located within the city of Santa Cruz de la Sierra, Bolivia. It is one of the oldest airports in Bolivia and has historically served as the primary aviation hub for the Santa Cruz region. The airport primarily handles domestic flights and some regional services, while the larger Viru Viru International Airport (VVI) located outside the city handles most international traffic to and from Santa Cruz. El Trompillo is situated close to the city center, making it convenient for passengers traveling domestically. The airport also serves as a base for the Bolivian Air Force and hosts general aviation and charter operations. Its central urban location has led to ongoing discussions about its long-term future as the city continues to expand around it.
