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.

An extraordinary and disturbing landscape. The remains of ore oxidize in the open air and release the metals they contain: iron, manganese, cobalt and arsenic. We thus find red runoff waters that must absolutely not be touched

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.
