Roannay Wet Meadows

Highlight • Natural

The stream has good biological and ecological quality. A study commissioned by the Walloon Region in 2014 noted a good presence of trout, sculpins and small lampreys, which are species of great ecological value, and qualified the biological quality of Roannay as good to very good (both for fish and for diatoms, macrophytes, macroinvertebrates). However, the banks of the stream have many colonies of Japanese knotweed and Himalayan balsam.

Roannay Stream

Highlight • River

This stream in the Belgian Ardennes has its source north of Francorchamps. It quickly forms a deep valley, wooded and very sparsely inhabited. Then, the valley takes on a more bucolic aspect and the pastures follow the forest areas. There are many viewpoints to the delight of hikers. The Roannay then crosses the hamlets of Ruy and Moulin du Ruy before finishing its course of 11 kilometers on the right bank of the Amblève in Roanne-Coo between the Coo waterfall and the village of La Gleize.

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.

Lower Reservoir of the Coo-Trois-Ponts Hydroelectric Power Station

Highlight • Lake

A green site, where you can discover two lakes (upper and lower) which, thanks to the passage of water in the turbines, produce electricity. A walking path invites you to go around the lower lake, before leading you to the Coo waterfall, where you will find various catering offers.
