Very nice climb. Small, narrow and very peaceful road in a forest environment. Personally, I absolutely do not find this climb to be the most difficult in Belgium. The ascent is even very pleasant, the gradient is reasonable and constant.

The climb is relatively challenging and long, but crossing the village of Kin-Stoqueu offers a beautiful view of some parts of Aywaille. The route finishes on level ground near the E25 motorway.

The Col du Rideux: a gem in Luxembourg's Aisne Valley and a favorite among climbing enthusiasts. The 2.6 km climb (avg. 6.2%, 160m elevation gain) winds through a dense forest and is actually divided into two sections. After the hairpin bend, it seems to be over, but then comes a challenging final half kilometer at 8%. The road surface isn't in the best condition, but the climb has charm. Fun fact: rumor has it that this was the first climb in Belgium to be designated a "Col"!

At the sign of the highest point there is a warning against ticks and Lime disease, Good thing. We were also lucky because a day later we could not have walked this walk because of the Hunters.
