The 2,072 m mountain pass at the head of the Val d'Aran — the valley's sole land route until the 1948 Vielha tunnel, a spectacular summer drive or cycle.

The pass at the head of the valley

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 about 8 km southeast of Baqueira that gives the resort's third ski sector its name and links the valley to the Pallars.

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. It's now a celebrated cycling and driving climb in the summer months.

How to do it from Baqueira

It's a short run — about 8 km, 15 minutes — up the C-28 toward Esterri d'Àneu. The road is drivable in summer but liable to winter closure, so check the road status before you cross. In winter the Bonaigua ski sector runs on the slopes above.

What to see

The summit viewpoint over the Aran and the Pallars, the hairpin road itself, and — for cyclists — one of the great Pyrenean climbs. A stop of twenty or thirty minutes is enough, or make a half-day of the drive.
