Historia
Cómo surgió
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.
Lo que verás
Durante la visita
The summit viewpoint over the Aran and the Pallars, the hairpin road, and — in winter — the Bonaigua ski sector on the slopes above.
Cómo visitar
On the C-28 between Baqueira and Esterri d'Àneu; drivable in summer, liable to winter closure — check road status before crossing.
Mejor momento
Summer for the drive; winter for the ski sector
Cómo llegar
Bueno saberlo
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.
