Tour in Coo around the reservoir. Quite a few meters of altitude to move. Some parts you unfortunately do twice but all in all a nice hike.
For 10€ you can park for 10 hours at Coo waterfalls.

February 27, 2022,Belvédère Thiry – Cascade de Coo Runde von Trois-Ponts

Finally back in the Ardennes 🥾
I actually wanted to do this tour in mid-December last year. At that time there was a hunt and I could only do one loop around Trois Ponts.
Bright sunshine, icy wind in the heights, scrambling over trees and a lot of mud due to the thaw. Not to forget, once again a path …

June 27, 2024,Coo bassin inférieur – View to La Gleize rondtocht vanuit Trois-Ponts

The tour is said to be tough - which is generally not too bad. The heaviness is probably in the length. But a very nice trip, especially on unpaved roads. Where I expected a view over Coo, it was a bit disappointing: too many bushes.

October 2, 2021,Belvédère Thiry – Cascade de Coo Runde von Trois-Ponts

A great hike through the Ardennes to the Cascade de Coo.
Again and again great views of this harsh landscape.
At the beginning there was unfortunately a barbed wire barrier from a pasture to the hiking trail, I crawled through without permission… .😉
Have a nice weekend to all of you 🙋‍♀️

May 26, 2022,Randonnée Nordic Walking à Coo

Take the time to warm up well before embarking on this course which begins with a 3km ascent interspersed with one or the other slight descent. If the gradient goes up to 20%, the places crossed are absolutely beautiful. The route is recommended for Nordic walking enthusiasts.
