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.

Today I wanted to try to see it in the harsh light of midday, which is not usually very good for photos, and still ... it is a special place.

It took me a lot to go down to the cave: it has a loooong slope and it's full of leaves. And that the ground was dry. I got just to enter the cave but I did not go down the, I think, meters of difference in level from the mouth.
