Port Ainé is an 18.4 km (11.4 mi) paved climb in the Pallars Sobirà region of Lleida province, in Spain's Catalan Pyrenees. Starting from the small village of Rialp, the road climbs at an average grade of 6.6%, gaining 1,267 m (4,158 ft) on its way up to the Port Ainé ski resort, a Ferrocarrils de la Generalitat de Catalunya-run station opened in 1986.
What makes this climb stand out is its modern racing pedigree: Port Ainé has hosted five Volta a Catalunya summit finishes since 2012, with winners including Janez Brajkovic (2012), Daniel Martin (2013, who took the overall race lead here), Thomas De Gendt (2016), Esteban Chaves (2021), and Tadej Pogačar (2024). It's a quieter, less famous ascent than the Pyrenees' big-name cols, but it carries real recent professional history.
The upper mountain is remote and forested, tucked inside the Alt Pirineu Natural Park, and the road exists mainly to serve the ski resort - so outside of winter and the rare race weekend, traffic is light and the setting feels genuinely wild. Rialp itself is a compact Pallars Sobirà village that doubles as a base for whitewater rafting and kayaking on the Noguera Pallaresa river running through town.

Port Ainé climbs 18.4 km (11.4 mi) from Rialp up to the Port Ainé ski resort, gaining 1,267 m (4,158 ft) at an average grade of 6.6%. The road starts around 755 m (2,476 ft) in the valley and tops out near 1,980 m (6,496 ft) at the resort base.
The climb isn't uniformly steep - the steepest kilometer averages 10.0%, and the steepest quarter-mile ramps up to 11.5%, with the hardest pitches concentrated in the switchbacks below the resort. This climb currently ranks #473 in PJAMM's world difficulty ranking.
Roadway: The road from Rialp to the Port Ainé ski resort is paved for its full 18.4 km (11.4 mi), though it narrows through the upper switchbacks. Cyclist reports describe patches of rough pavement in places, particularly on the descent, but we found no report of an active repaving project or closure as of 2026 - check with the Diputació de Lleida's road office before a winter or early-spring visit, since the upper section serves a ski resort and can ice over outside summer.
Traffic: Traffic is light for virtually the whole climb. The road exists mainly to serve the ski resort and a handful of trailheads, so outside of the winter ski season and the occasional Volta a Catalunya race day, you'll mostly share it with other cyclists and hikers.
Parking: Rialp is a small, tourism-oriented village with free parking along its main street, a sensible place to leave a car before starting the climb. At the top, the Port Ainé ski resort has its own free parking at multiple levels near the base area, plus an additional lot beside the Hotel Port Ainé 2000 - useful if you'd rather start a shorter ride from higher up the mountain.
Gear: Standard road gearing handles Port Ainé's 6.6% average without trouble, but pack an easier low gear for the switchbacks near the top, where segments push past 10-11%.
Provisions: Rialp has grocery and food options as a tourism hub for the Pallars Sobirà, so stock up before you start - there's nothing along the climb itself until you reach the resort's restaurants at the top.

Rialp is a compact Pallars Sobirà village and a good base for more than just this climb - it's also known locally for whitewater rafting and kayaking on the Noguera Pallaresa river that runs through town. The climb itself has real recent racing pedigree: five Volta a Catalunya summit finishes since 2012, won by Janez Brajkovic, Daniel Martin (who took the overall race lead here in 2013), Thomas De Gendt, Esteban Chaves, and Tadej Pogačar.
Rialp also sits at the base of several other, less-documented Pallars Sobirà climbs, so it's worth treating as a multi-day cycling base rather than a single stop. For other climbs radiating from the area, our Routes in the Area tool is a good way to see what else is nearby.
