I went in July 2023. This cave is completely closed. There are signs from the Basque government saying DO NOT ENTER (and explaining the consequences and the work they're doing) and plastic tape blocking the entrance. There are lots of constructions tools around too. Don't expect to get in unless you're willing to destroy the small stone wall and all the tape blocking the entrance.

The Portupekoleze arch-cave, located in the Urbasa mountain range, is the spectacular result of water erosion, which over the millennia has created this enormous arch in the rock.

Beautiful arch very close to the sale of Lizarraga. It can be accessed from the lower track or going up close to the cut from the inn itself. You can go down to the lower cave. This arch is an unavoidable "must" if you are in the area.
