beautiful climb starting from the valley of Larrau. Count 21km but the bulk of the elevation gain starts in Saint Engrace

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.

Hidden among the undergrowth, you climb up a small path next to the bridge, the interior is flooded.

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.
