Somewhat difficult paths to walk, but the view is worth the effort! The descent through the bar's terrace was particularly interesting.

Built in 1904 on the Paseo de los Fueros in San Sebastián. Between 1972 and 1975, it was moved stone by stone to its current location. It is the headquarters of the Aranzadi Natural Sciences Society.

Although now only a few ruins remain of what once was, a castle once stood here. There is now an area with picnic tables, ideal for stopping for lunch. If you get here by one of the trails that arrive, a little before you will also pass by a small pond.
