Bailleul-sur-Thérain walks

Discover two contrasting natural environments: the dry limestone grasslands covering the hill of Mont César and the marshes below. A varied route through the forest, poplar groves and fields.

The Hez-Froidmont forest was created in 1869 by combining the Hez (1,413 ha) and Froidmont (259 ha) state forests with the Saint-Lucien, Saint-Thibault and La Verrière reserves, which were originally owned by the church. Covering a single area of 2,796 hectares (with the exception of the Belle Fille valley, which is 100 metres away from the forest and represents a small 10-hectare canton), it stretches 9 kilometres from east to west and 6 kilometres from north to south.
