A great post through a high valley with beautiful views. Most of the time you are alone here. There are a few technical passages in between and you should have at least 40mm tires

From the Pallars, the hardest section is the straights of the Gerdar, before the Ares. Once you reach the pans, the gradient varies but everything becomes much smoother. Highly recommended.

Incredible climb that connects the Pallars Sobirà with the Aran Valley. From the Pallars, the hardest section is on the straights until before the hermitage of Our Lady of the Ares. Once here, the pans gently take us up to the neck. Highly recommended.
