The Port de la Bonaigua is one of the great Pyrenean passes, with a challenging climb that immerses you in majestic landscapes and high mountain scenery. Reaching the summit by bike is a legendary experience that connects Pallars with the Val d'Aran, amid curves and breathtaking views.

In fact, for the Aranese of the Val d'Aran, the real source, the Uelh dera Garona (eye of the Garonne), is located in the pastures of Plã de Béret, near the Baqueira Beret ski resort, therefore after Viehla BUT according to Norbert Casteret (search for the source with dyes in the 1930s), the main source is located to the east of the Maladeta massif, in Aragon, from the northern and eastern snowfields of the Aneto peak, whose water rushes into the Forau d'Aigualluts or Toro hole (altitude: 2,074 m), to change valleys by a resurgence at the Uelhs de Joeu (Eyes of the Jew) (at 1,658 m). 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)

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.

Large village where we can find several bars and shops. From here we can go up to the gate or follow the valley of Aran, either up to find Vielha or towards Les. From Les we can take the Col de Menté, highly recommended, or go in search of the Col de Balés - incredible.
