Two tours in one to discover in one or two separate walks, between Mont-sur-Marchienne and Montigny-le-Tilleul: a tour of almost 4 kilometres and a shorter one covering 1 kilometre in the nature reserve.

Twenty stations, outstanding wildlife, a wide variety of plant species ... a great way to enjoy a breath of fresh air.

This delightful walking tour delves into an eventful geological past, along the wooded banks of the Eau d'Heure, through peaceful hedge farmland and a fascinating limestone hillside with its old quarry.

Paths and rivers, meadows and railway lines, this is an opportunity to discover an exceptionally rich biodiversity.
