Au Cœur de l'Ardoise is an old slate quarry in Bertrix where you descend 25 metres underground into the history of the Ardennes. The mine was active until 1976, and today you walk through gigantic halls blasted from the rock.

- Mine Gourmande: visit + 3-course meal with local produce (from 10 people)
- Underground beer tasting (groups from 10 people)
