Reconnect with nature on a guided walk with Val du Flot! Discover the fascinating power of trees in the landscape of the mining basin. True pillars of biodiversity, trees tell the story of the reconversion of our slag heaps and industrial wastelands.

The mining basin offers spectacular reborn nature: slag heaps covered in pioneer forests, subsidence ponds harbouring rich wildlife, and trees playing an essential role in air and water purification.

An ideal outing for nature lovers, families and anyone wanting to better understand the unique ecosystem of the mining basin.
