Carving a spectacular path through the heart of the country, the Rio Zêzere is still a hidden gem.

Rising from the glacial valleys of the Serra da Estrela, Portugal’s highest mountain range, it rushes southwest as the second-largest river entirely native to Portuguese soil.

Along its journey, various river beaches can be found. One is more beautiful than the other. Mostly surrounded by the great forests of the central region.

The river's true modern legacy, however, is defined by its massive barragem network. The Zêzere is a crucial powerhouse for the nation, harnessed by colossal engineering marvels like the Cabril, Bouçã, and Castelo do Bode dams.

These reservoirs do not just generate massive amounts of clean hydroelectric energy; they provide many with fresh water. As this system is what largely supplies Lisbon with its water.
