Cerrillos Airport, identified by ICAO code SLER, is a small regional airstrip located in the Hernando Siles province of Bolivia. It serves the remote communities of the region, providing limited air access to an area that is otherwise difficult to reach by road. The airport operates at a basic level of infrastructure, typical of rural Bolivian airstrips, and primarily supports light aircraft and small regional flights rather than commercial jet service. It plays an important role in connecting isolated communities in the Bolivian lowlands.
