Aizkorri Refuge and Hermitage

Highlight • Mountain Hut

The Aizkorri Free Refuge is located in one of the most visited ranges of the Basque Mountains, because it is home to Punta Aitxuri, the roof of Guipuzcoa

Right next to the Aizkorri, so it's a shame to miss it! without major complication of arrival.

Altuna Peak

Enjoy the views because from this point begins a technical and long descent through the mountain gorge.

San Adrián Tunnel

Highlight • Cave

Curious formation that allows us to go from one side of the mountain to the other.
Be careful if it is wet or damp as the stones slip a lot.

September 4, 2025, Im Nationalpark Aizkorri-Aratz (Baskenland )

One last mountain hike in the Basque Country before we head inland. Unfortunately, the view at the top was so disappointing that we had to cut it short 🥱🤷‍♂️

Translated by Google

The Aitxuri is a mountain with an altitude of 1551 meters in the Sierra de Aizkorri, belonging to Guipúzcoa. It is the highest peak in this mountain range and in the entire Basque Country. A moderate route in good weather but with wet ground and wind it can get complicated as we will have slippery rock and mud for most of the way. On this route we will take the opportunity to visit the sister peaks Aizkorri and Aketegi.
