The Wild Road to Collado de Sahun

# Collado de Sahún: A High-Alpine Adventure in Spain's Aragon

Ready for a proper mountain challenge? Collado de Sahún sits at a breathtaking 1,998m (6,555ft) in the heart of Aragon's remote highlands, straddling the boundary between Gistain and Benasque valleys. This isn't your average scenic drive—it's a full-on alpine expedition.

The 24.1 km road stretches east to west from Chía to Plan, and honestly, those kilometers pack a punch. Built back in the 1970s, Pista de Chía is mostly unpaved with some concrete sections—smooth enough for regular cars if you're brave, though SUVs with decent ground clearance will thank you later. The real story here? Uncountable turns, 20 hairpin bends, and sections that climb at a gut-wrenching 25% gradient. Loose gravel keeps you honest, and the narrow, steep sections demand serious respect.

What you get in return is absolutely worth it. The official summit overlooks the jaw-dropping Barranco Llisat, though the road actually peaks slightly higher at 2,028m. Along the route, you'll find a mountain refuge (Refugio Puerto Sahún) and scattered viewpoints that'll make you forget to breathe. If you're familiar with French passes, think Luz Ardiden vibes on the Plan side, with a dash of Col de l'Aubisque character on the Ribagorzana approach.

Fair warning though: come winter, this pass essentially shuts down. The northern-facing western sections and unpredictable weather make maintenance a nightmare. Fog and rain are regular visitors. Rock slides are a genuine hazard. But for summer adventurers seeking something genuinely wild? This is the real deal.
