Thiry Belvedere Observation Tower

Highlight • Viewpoint

The few steps up are definitely worth it. From up here you have a great view. The tower is located near the upper chairlift station of the Plopsa Coo attraction park.

Coo Waterfall

Highlight • Waterfall

The waterfall is one of the highest in Belgium with a drop of 15 meters. There is a staircase between the two waterfalls, from where you can admire the impressive flow of water masses. The falls are a tourist attraction so there are a few cafes nearby.

Roannay Stream

Highlight • River

The Roannay is a stream in Belgium, a tributary of the Amblève and part of the Meuse watershed. It flows entirely in the province of Liège.
The stream has good biological and ecological quality. A study commissioned by the Walloon Region in 2014 noted a good presence of trout, bullheads and small lampreys, which are species of great ecological value, and described the biological quality of the Roannay as good to very good (for both fish and diatoms, macrophytes and macroinvertebrates). However, the banks of the stream have numerous colonies of Japanese knotweed and Himalayan balsam.

Very nice nature walk, good shoes required. In Roanne it is difficult to park, it is a small hamlet, but where there is a will, there is a way.
