Much more modest than the famous "Big Cave," but very interesting. It has a small bar, like a pub.

A beautiful two-eyed cave, normally occupied by flocks of sheep. It's a detour from the PR trail that descends from the Artola pass, to which you must return, unless you want to descend through the "very muddy" section of the Sagasta neighborhood.
