I am walking the GR 412 – Sentier des Terrils.
There are a lot of terrils (slag heaps) in Belgium, about 740 in Wallonia alone, mostly lying on the Liege — Charleroi — Mons — Lille axis. The GR 412 follows this axis.
Below is a list of terrils my walk put me on, or directly next to. There are many more I have seen.
The list will be updated as my walk progresses.
A full list of terrils (about 740) is available on the Geoportail Wallonia.
A map is visible on terril.be, as well as a searchable list.
The altitude data in this table is eyeballed from the Geoportail Wallonie.

I hand-guessed the altitudes from the Geoportail, adding the following layers:
- Relief de la Wallonie – Modèle Numérique des Pentes 2013-2014 classifié,
- Relief de la Wallonie – Modèle Numérique de Surface (MNS) 2018 – Photogrammétrique
- Terrils (Version 2018)
Then eyeballing the highest point and calculating the height above ground by averaging four points around the terril. But a flattened terril on a slope can give an exaggerated height. So I changed the value to what I beleived was a natural one.
