Tiétar

Tiétar is a river in central Spain, part of the Tagus river basin. It originates in the Sierra de Gredos and flows generally southward across the eastern edge of the province of Ávila and into the western part of Cáceres, passing towns such as Arenas de San Pedro and Candeleda. In its lower course the Tiétar joins the Alberche, and through it its waters reach the Tagus.

Geography and course

The river’s headwaters lie in mountainous terrain, where climatic conditions influence its seasonal flow. The Tiétar valley hosts a mix of agricultural land, riparian woodland, and settlements that historically developed along the river. The course is characterized by variations in elevation and landscape, from highland areas to more open valleys as it approaches the Alberche confluence.

Hydrology and ecology

Discharge is strongly seasonal, with higher water levels in spring due to snowmelt and rainfall, and lower levels in summer. The river and its banks support a range of aquatic and riparian habitats typical of central Iberian river systems. Human use includes irrigation and other water-management practices, which interact with natural processes and local biodiversity.

Economy and culture

The Tiétar valley has long supported agriculture and rural communities. Tourism and outdoor recreation are strengthened by the landscape, historic towns, and proximity to mountainous areas. The upper basin lies near protected natural areas, contributing to the region’s ecological and scenic value.
