Nature Reserve Banks of Castronuño, Protected natural area in Valladolid province, Spain.
The Nature Reserve Banks of Castronuño spans 8,420 hectares of wetlands, forests, and riverbanks along the Duero River in western Valladolid province.
The San José dam construction in the 1940s transformed the river basin, creating extensive wetlands that became the foundation for this protected reserve.
The reserve educates visitors about environmental conservation through its Park House, which offers guided tours and educational programs about local ecosystems.
The Park House welcomes visitors from Thursday to Sunday, providing information materials, audioguides, and access to multiple walking and cycling paths.
The reserve contains semi-natural wetlands maintained by reservoir water levels, supporting large colonies of gray herons, egrets, and numerous water bird species.
