Collado de Sahún

The Wild Road to Collado de Sahún

Collado de Sahún is a high mountain pass at an elevation of 1.998m (6,555ft) above the sea level, located in the province of Huesca, Aragon, Spain.

Set high in the northern part of the country, the road to the summit is mostly unpaved with concrete sections, smooth enough for cars. Caution with loose gravel. It’s called Pista de Chía. The pass is 24.1 km (14.97mi) long, running east-west from Chía to Plan. The road is not easy, with uncountable turns, twists and 20 hairpin turns. SUV’s and vehicles with high clearance are recommended. Very steep and narrow sections along the track, hitting a 25% of maximum gradient through some of the ramps.
The pass can be approached from either side. The official pass is at 1.998m and overlooks the spectacular Barranco Llisat, but the actual highest point on the road is a little above that, at 2.028m (6,653ft) above the sea level. Risk of rock slides. Along the way are a few viewpoints.

Located on the boundary of Gistain valley and Benasque valley, within the Chia mountain range, this road is usually impassable in winters.  The open and close dates all depend on snowmelt and snowfall each year, but snow may block trail well into May-June. Large sections of the west side are facing north, so keeping the road open in winter and maintenance works would be costly. Fog and rain are common.
