A peak very close to Hernio. It's highly recommended to visit it after reaching the summit of Hernio, as the descent from this point to the Iturrihotz hamlet is much more manageable.

Absolutely breathtaking!

Super beautiful cliffs! Unfortunately, it was still high tide where we were, so the flysch cliffs were only visible at low tide. Check the tides at tideschart.com.

The first (or last section if reversing the route) section is absolutely NOT accessible. Possibly only at extreme low tide. We were there an hour before extreme low tide, and it was completely impossible. I would choose to simply follow the route at a higher elevation and skip the "beach" section. Especially since the beach is made up of large stones and rocks, difficult to walk on because you always have to watch your step due to loose stones.

Mostly the area is windy especially due to topography. Do not forget to carry water with yourself. Enjoy the Bay of Biscay
