Barcena Mayor is in the River Saja Valley. It is located in the heart of the Natural Park. Since the Roman times it was the way to Castilla la Vieja.
You are surprised at the evergreen landscape. Canoeing, trekking and riding on horse back or riding a bike can make your journey an unforgettable one, mainly in summer, autumn or spring time although winter is wonderful too . http://http://parquesnaturales.consumer.es/documentos/cantabria/saja_besaya/index.php
