Col d'Aspin, rising next to its neighbor Tourmalet, is a shorter and easier climb that is often featured in the Tour. Along with its bigger brother, it is a classic of enduring fame. Cycling Col d’Aspin is possible from very early until late in the year because it is lower in elevation than most other climbs in the Hautes-Pyrénées. Gradual and without any long sections over 9%, Aspin is a good climb for moderately fit cyclists or to ride in combination with other climbs (view my various routes). I particularly recommend it in May, when it offers splendid vistas on all the surrounding snow-capped mountains before the road to Tourmalet even opens.
