Estero Limache is a stream system flowing through the Valparaíso Region of central Chile, draining the coastal mountain range and passing through the town of Limache before eventually contributing to the broader lowland wetland network of the region. The stream runs through a Mediterranean-climate landscape characterized by dry summers and wet winters, with flows that respond strongly to seasonal rainfall patterns. The surrounding riparian corridor reflects the native sclerophyllous vegetation typical of central Chile's coastal valleys, with the stream corridor providing important habitat connectivity in an otherwise heavily modified agricultural and urban landscape.
