The Sint-Pietersbos is the eastern extension of the Muziekbos. This former private forest covers over 52 hectares. The Muziekbos (50 hectares) was almost completely clear-cut during the First World War, but the Sint-Pietersbos was preserved. It boasts a unique collection of old summer oaks and American oaks, beeches, and ash trees, all 150 years old. (City of Ronse)

Superb forest path, in relatively good condition and with a gentle slope. Be careful, it can be quite slippery when it's wet.

The Sint-Pietersbos was purchased by the Flemish government in 2011 from the noble family Gautier de Rasse. The forest area is partly a forest reserve. The Sint-Pietersbos is located on the territory of the municipality of Ronse. The forest was already indicated on the Ferraris map as 'St Peetersbosch'. The forest is managed by the Flemish government agency Agency for Nature and Forests. The forest is recognized as a European Natura 2000 area (Forests of the Flemish Ardennes and other South Flemish forests) and is part of the Flemish Ecological Network.

Away from the hustle and bustle. Enjoy the mystical Livierenbos. The mystical Livierenbos is a large old forest with open spaces located on the border of the Flemish Ardennes and Pays des Collines. In this large forest, too, the bluebell is the main character every year in April. Historical significance: the name of the forest – in French Bois de la Louvière – is Romanesque in origin and refers to the presence of wolves. Wolves lived in the forest until the 17th century, which regularly led to fierce hunts. With the knowledge of the past (werewolves) and the possible appearance of flying witches, it is doubly enjoyable and we stroll dreamily along blue-purple carpets through the present.
