In the town of Oñati, Arritrutz is an underground Baroque cathedral built by nature and formed by over a dozen kilometres of interconnected tunnels, of which 500 m can be visited. This was home for prehistoric wild animals such as bears, panthers and lions - look out for their footprints! The visit takes one hour.
