Ribeira de Pera rises in Serra da Lousã, more precisely in Porto Ervideiro, at 1180 meters above sea level. It crosses the municipality of Castanheira de Pera and Pedrógão Grande and flows into the Zêzere. Along the way, there are other points of interest, such as the caster mills and the old oil mill.

Zêzere River Dam, is one of the largest Portuguese dams and also constitutes one of the largest freshwater reserves in the country. The landscape from here is imposing.
