Cyclist reaching summit of Hautacam in the French Pyrenees

The Tour de France has held a summit finish at Hautacam no less than five times with Vincenzo Nibali the last Tour champion to claim stage honours in 2014. For a climb which is just over 14kms long, it sure packs a lot of punch. From Argeles Gazost you can look across to the mountain peak looming large, and it is one you won’t quickly forget once you have reached the summit.

Undulating gradients

The climb is located just 3 kms from the centre of Argeles Gazost so we recommend riding a bit further along the valley floor beforehand in order to warm up the climbing legs. What the Hautacam lacks in length it makes up with sheer steep and relentless ramps. The gradient is always forever changing which means it is hard to get into a smooth climbing rhythm to settle into on the climb. One kilometre is 6% the next will hover over 10% and it continues this way for the entire climb. Whilst there is a brief downhill section partway along the climb, there are also sustained ramps of over 15% so make sure you keep this in mind and measure your efforts.

Stunning rural vistas

Whilst you may be cursing the unrelenting steep gradients on the climb, make sure you take a moment to enjoy the stunning views afforded to you as you begin to rise in altitude. The views down across the Vallée du Lavedan are spectacular and will hopefully provide you with some distraction as you tick the kilometres off. Green lush pastures meld into the surrounding peaks leaving you with a true sense of the tranquil beauty and ‘rustic’ feel of the Pyrenees.

Reaching the summit

The third last kilometre is by far the hardest and averages well over 10%. After this last test of the legs the final two kilometres are relatively easier and your goal of the summit will be upon you. The summit itself is a rather uninspiring ski station car park. We do recommend heading on further up the road for another 1.5kms until you reach the very top known as the Col du Tramessel. Given you have come this far what is another bit of climbing! Once at the top enjoy the views and the fast descent back the way you came to Argeles Gazost.

The Col de Tramassel is only an extra 1.5km /1mi from the top of Hautacam and worth the extra altitude to get to.
