While the ascent of the slag heap is flat and gently uphill in its first part, it is followed by a long, steeper section of walking before reaching the summit. It is clearly stated that descending via any route other than the designated access point is strongly discouraged due to the risk of rockfalls.

A truly amazing site. Bring a lock, as you have to leave your bike at the bottom of the steps.

The highest point of the Loire Atlantique (slag heap). Nice circuit to go around it.

This deep mine excavation is now a beautiful lake and hiking spot. The calm waters offer amazing reflections from the shore.

A former source of tin, this site has long been used as a mine. The slag heap, which is said to be 70 to 121 meters high, is a magnificent vantage point. An orientation table is also at the top to enhance your experience.
