On the heights of Belleu, follow our guide and discover the natural site of Pierre Frite. Several floral species characteristic of the limestone lawns of Soissonnais await you, such as the Orchis moucheron. This site, managed by the Conservatory of Natural Areas is also a place steeped in history, where the trenches of the First World War are still distinguished. There are two day trips from Soissons. The bus can accommodate up to two classes.
