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.

Within the Urbasa-Andia Natural Park is this wonderful place with an interesting history related to its name. In addition to being one of the most spectacular caves in the area, its name dates back to the Carlist era in which it is said that General Zumalacarregui threw the shot soldiers of the other side, who were known as Cristinos or Isabelinos. Before going to the place, I recommend that you check on the official website if access is open, a while ago it was closed due to COVID (http://cuevacristinos.com/)

The Ezkiza flat is right where the road ends and the Otxaportillo track begins. An incredible place where you can enjoy not only the views but also the cattle grazing peacefully in this unique environment.
