One of the climbs I discovered during the Tour de Namur Cyclo in 2025. It's a Cotacol climb, number 227, but it's definitely one of the encyclopaedia's favourites: steep yet regular, quiet, in very good condition. Personally, I would have liked it to have been even longer, but it's difficult to combine steep gradients with great length in the Condroz.... read more

Une des côtes que j'aurai découvertes lors du Tour de Namur Cyclo de 2025. C'est en effet une côte Cotacol, la numéro 227, mais celle-ci est carrément un des coups de cœur de l'encyclopédie : pentue tout en étant régulière, forestière, tranquille, un très bon revêtement déjà à l'époque. Pour ma part, j'aurais aimé qu'elle soit plus longue encore, mais c'est déjà difficile de conjuguer pente forte et longueur conséquente dans le Condroz.

Very nice climb - previous comments from 3y ago can still be confirmed today (steep, nice, quiet and good road surface). I didn't know this one and didn't know it was in the route, so pleasant surprise. Although it was gruelling.

Zeer leuke klim - de vorige reacties van 3j geleden kunnen ook nu nog worden bevestigd (steil, mooi, rustig en een goed wegdek). Deze kende ik niet en ik wist niet dat deze in de route lag, dus aangename verassing. Al was het wel afzien.

Very nice climb, much steeper than the other side. The slope is regular but quite steep. The road is in good condition and there is not much traffic in general.
Worth a try!

Très belle ascension, nettement plus raide que l'autre versant. La pente est régulière mais assez forte. La route est en bon état; et la circulation en général peu présente
A essayer !

Cotacol: Chansin-Sud. Not very well known but a must if you are in the Bocq valley. The slope is very regular up to the top and does not leave you any respite. A climb not to be underestimated. You need good legs.

Cotacol : Chansin-Sud. Peu connue mais une incontournable si vous passez dans la vallée du Bocq. La pente est très régulière jusqu'au sommet et ne vous laisse aucun répit. Côte à ne pas sous-estimer. Il faut de bonnes jambes.

I found this to be quite a tough climb. Too steep to ride really nice pace and too long to do it on power.

Ik vond dit best een pittige beklimming. Te steil om echt lekker tempo te rijden en te lang om hem op de kracht te doen.

The road between Durnal and Dorinne offers a much steeper climb in the direction of Dorinne than in the direction of Durnal. During the climb you'll cycle over a railway viaduct with a view on the rock formation in the quarry of Durnal, well known among rock climbers.

De weg tussen Durnal en Dorinne levert in de richting van Dorinne een veel steilere klim op dan in de richting van Durnal. In de klim fiets je over een spoorviaduct met zicht op de rotsformatie in de groeve van Durnal, bekend onder rotsklimmers.
