In Thuin, the Bois du Grand Bon Dieu offers a hike with very varied atmospheres. Under the tall trees, the paths alternate between shaded passages, more open paths, and small reliefs that give rhythm to the walk. A simple and authentic nature, far from the major tourist sites, but which is well worth discovering.

Clinging to the hillside of Thuin, the Hanging Gardens offer a truly unique landscape. These terraces descending the slope of the Biesmelle valley form a real patchwork of gardens, stones, and greenery. A place where one takes as much pleasure in looking at the landscape as in imagining the history of these terraces once cultivated by the inhabitants of the town. One of Thuin's treasures, to be discovered along the hike.

Although the place is quite small, with its rocks, it almost feels like the Fontainebleau Forest. A rather unusual environment for Hainaut.

The long slope is doable, she also goes straight to straight. The descent, however, is a different soup... Good luck!

It is at the confluence of the Trouille and the Nouvelles river that this waterfall bridge was born. Originally there was a mill, which was turned into a tannery after the First World War. Today it is a bucolic place surrounded by nature.

By definition, a menhir is a vertical standing stone during the Neolithic era. The menhir of Saint-Symphorien, 2m50 high, 1m30 wide, weighing 2500 kg, also served as a Neolithic ribbon brush for flint tools. It was discovered in 1860 by Mr. Piscart, a farmer who broke his ploughshare while plowing his field, located at the end of the Violette path, on the border of Harmignies. The menhir was then excavated to stand in the park of the Maigret de Priches castle, where it remained for 90 years. On October 17, 1951, the megalith was presented by Miss Emmy Maigret de Priches to the city of Mons. At the request of the Sint-Symphorien Brotherhood, he was reinstalled on March 20, 2007 in the village. http://www.confrerie-saint-symphorien.be/?page_id=307
