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.
