Whoever talks about the Walloon territory south of Sambre and Maas automatically thinks of the Ardennes. In the furthest southwest corner of Wallonia, however, there is another region, which is visibly different from the Ardennes: De Gaume. The 140 kilometer long circular walking route "Transgaumaise®" shows you the most beautiful of this remote part of Belgium.

The Centennial Trail was established in 1970 and is now a section of The Great Trail (TGT). The trail cuts through Pre-Cambrian Boreal Shield in Whiteshell Provincial Park. Traditional Indigenous Territory of Michif Piyii (Métis), Anishinabewaki, ᐊᓂᔑᓈᐯᐗᑭ, and Očhéthi Šakówiŋ. 

The trail offers stunning views and a true wilderness experience. It follows high granite ridges and low areas of boggy boreal forest. There are difficult sections with steep rock slopes. Trail users should look for rock cairns for way finding in sections with few trees. Water can be scarce along the way.
