- Santuario de Aranzazu - The next stop is the 1950s Sanctuary of Arantzazu, a stunning monument perched above rugged rocks, renowned as one of the most avant-garde religious structures globally! Esteemed Basque artists such as Néstor Basterretxea, Eduardo Chillida, and Jorge Oteiza contributed to this remarkable project. The Sanctuary’s surroundings are truly breathtaking!
- Aizkorri-Aratz Natural Park - With the basilica’s spiritual energy, the ascent of Mount Aizkorri begins. These rocky peaks are undoubtedly the highest and most picturesque formations of sharp limestone massif in the Basque Country.
The trail initially leads through a treeless yet verdant landscape dotted with ‘latxa’ sheep and steeped in local legends. Gradually, the grazing pastures transform into rugged rocks, and above the mountains, birds of prey such as peregrine falcons, griffon vultures, and booted eagles can be seen gliding.
At the mountain’s summit, enjoy panoramic views and a well-earned rest! It’s the perfect time to savor a delicious lunch featuring top-quality local specialties like Idiazabal cheese, cured sausages, ham, and tuna fish from a nearby port.
- San Adrian ermita - It’s decision time! Choose between descending on your own through the San Adrian tunnel or retracing your steps with the guide. The first option is recommended, allowing you to appreciate both sides of this impressive peak and explore a historically significant natural cave known by the ancients as the ‘hole to hell’. The guide will provide all necessary information and a Walkie Talkie to ensure a safe hike completion!
- Aldaola-Ubier aparkalekua - Congratulations! After a 17 km hike, return to the car where your guide will treat you to a glass of local wine before heading back to San Sebastian.
