Port de la Bonaigua

Mis à jour 2026Vérifié à piedBetween Naut Aran and Pallars Sobirà

The Port de la Bonaigua is the high mountain pass at 2,072 m that closes off the head of the Val d'Aran to the south — a spectacular, hairpinned road that gives the resort's third ski sector its name and links the valley to the Pallars.

Histoire

Comment le site est né

For centuries the Bonaigua was the only land route in and out of the Val d'Aran, cut off by snow all winter until the Vielha tunnel opened in 1948; the pass road still closes in heavy snow. It is a celebrated cycling and driving climb in summer.

Comment visiter

On the C-28 between Baqueira and Esterri d'Àneu; drivable in summer, liable to winter closure — check road status before crossing.

Bon à savoir

The Port de la Bonaigua tops out at 2,072 m. It was the only land route into the Val d'Aran until the Vielha tunnel opened in 1948, and the pass road can still close in heavy winter snow.

Often not — the high C-28 pass is closed or restricted to vehicles with snow chains in heavy snow, so in winter the reliable, all-weather way into the Val d'Aran is the N-230 through the Vielha tunnel. In summer the Bonaigua is a spectacular, hairpinned scenic drive and a celebrated road-cycling climb.
