A mountain for mountaineers; it's a pleasure to climb and admire the view from the top. You have to be a little careful with the rocks at the top.

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.

But keep in mind that all those that go to the south go up, logically, on the north faces, come on, they are usually full of mud ... better for when the weather is good.

From Salvatierra, a small road leads to the port of Opakua, with spectacular views over the Urbasa mountain range, in the nearby lands of Navarra. The views are awesome!
