After breakfast, it closes for a while for cleaning. Fill up your water bottle before heading up, as it's a scarce resource up there.

Located at an altitude of 630 meters, nestled in a green setting surrounded by gorges and peaks, the village of Sainte-Engrâce is a charming mountain village in the Basque Country. In addition to its 11th-century Romanesque church, don't miss the famous Kakuetta Gorges or the sublime Verna Cave.

I would not recommend right now. They recently did a chip and seal so a LOT of loose gravel. I live in the area and even the road to Osse en Aspe.

It is a very gentle climb that starts in the Zuriza valley and reaches the Liza refuge, where the paved road ends. The first km is the hardest with a 6% gradient, which then becomes easier with some sections that are slightly downhill. The most important thing on this climb is without a doubt the landscape that accompanies us to the refuge. In addition, it is 100% peaceful.

The monastery of San Pedro de Siresa is a beautiful Romanesque-style monastery located in the town of Siresa (two kilometers from the town of Hecho). It is the oldest monastery in Aragon. There are guided tours of the monastery... and it is well worth it.

A beautiful port that unites the communities of Navarra and Aragón, specifically the towns of Ansó and Isaba. Specifically, it connects the Zuriza valley with the Roncal valley. It is a very affordable port and highly recommended because it allows you to travel through spectacular landscapes, on both sides. The Navarrese slope is shorter but more difficult than the Aragonese slope, which is very steep, except for the final kilometer which is 7 - 8%. What has been said, I reaffirm that it is a beautiful port that must be enjoyed.
