Who said this is a flat region? There are more than 340 hill-like slag heaps in the UNESCO-listed mining basin that were formed over time during the coal mining era. From the top of the twin heaps in Loos-en-Gohelle, the view stretches as far as the eye can see – 19 miles (30 kilometres) and a 360-degree vista. They may rise steeply, and it’s great to see kids using their energy to climb higher and higher, in part motivated by the animals that dart across the path – lizards, blackbirds, blue tits and great tits have all made their homes here. Once at the summit, breathe the clean air, enjoy the silence and share the joy as a family. Good memories all round!
