It is at Plan dera Artiga de Lin (at the bottom of the small, almost uninhabited valley starting after the village of Es Bordes (instead of continuing on Viehla, leave the road on the right at Es Bordes to enter this small valley at the bottom of which is the resurgence)

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.
