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.

A beautiful valley with spectacular views, which can be accessed without difficulty (either from Ansó or from the Roncal valley), where you can breathe peace and tranquility and where you can enjoy a nice swim in the river on the hottest days of the year.

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.
