A half-Mordor, half-Mad Max atmosphere with these reddish-orange marshes. The color is due to the oxidation of heavy metals contained in these highly acidic waters: iron, manganese, cobalt, and... arsenic. It's actually due to severe arsenic pollution that access to the second spoil heap has been prohibited since 2019.
You can tour the site by bike, but it's clearly mountain biking/gravel riding (walkways, roots, rocks, etc.).
