After the Mondego, this is the second-longest Portuguese river. It rises in the Serra da Estrela, at an altitude of approximately 1,900 meters, and stretches for 242 km. Its main tributaries are the Nabão and Alge rivers, as well as the Isna, Paul, Bogas, Pera, and Unhais streams. It flows into Constância. Thanks to its water potential, flow, steepness, and rocky banks, it has been used for electricity generation.

Peak located in Serra da Tronqueira, allowing you to see a surprising landscape that goes from the slopes dotted with hydrangeas to the sea.

The views it offers over the historic area of Castelo Branco and the region greatly reward the effort required to reach it. It is located close to the Castle and opened in 1941, built to “hide” the water supply tanks and later reclassified during the Polis program. The garden benches and shadows invite you to take a well-deserved rest, while contemplating the panoramic view that goes from Serra da Estrela to the border.

The Unhais River is one of the many tributaries of the Zêzere River and runs through the slopes of the municipality of Pampilhosa da Serra.
