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.
