Although only part of the tower remains today, its presence is imposing: it was once a stately home and today serves as the perfect viewpoint over the Óbigo Valley. A bike ride up here is both visually and culturally rewarding. A great spot for epic photos, a restful break with views, and a bit of history on wheels. If you're planning a route with interesting stops, this castle is a definite yes.
