Castilla y León boasts an extensive hydrological network. Tourists are particularly drawn to the reservoirs, several of which offer visitors the chance not only to enjoy a cooling swim or a lazy day’s fishing, but also to carry out a series of water sports in motor and sailing boats.

In the summer season particularly, and thanks to the services and facilities offered by various bathing areas and lakeshore beaches, the reservoirs attract considerable numbers of visitors. However, they are also the ideal choice for activities such as canoeing, sailing or windsurfing, bird watching, rowing and even river cruises.
