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.

To get to the port, climb a narrow and very steep path, sometimes passing the odd snowfield, depending on the season. It is quite intense but not too long; when you get to the top (which you can see from Lake Obago), there is a small waterfall that you have to dodge on the left side. Once you pass this part, the simplest thing remains for you: cross a kind of meadow with a slight slope that leads to the port. There you have the view of the Circ de Saboredo.
