In the middle of a large, bright green pine forest, you suddenly find yourself in the heart of a desert landscape: this is the Lommel Sahara. This is a unique phenomenon, and remarkably enough it’s thanks to pollution. In bygone days, there was a zinc factory here, which caused the vegetation around it to disappear in one fell swoop. The result is a barren landscape covered by a layer of white sand. To prevent that surface from expanding, a brand-new pine forest was planted. Today, Limburgers would have it no other way. And just to give it more of a fairy-tale character, you’ll also find a small azure blue lake there (no, it’s not a mirage)!
