Don't miss the Loos-en-Gohelle slag heap, an astonishing and unusual spectacle. There are five hills made of coal waste, and this one is the highest, reaching 146 meters, the highest in Europe! Hike to the top and admire the views. You can see how nature has transformed the hills with plants, animals and even grapes. Take the opportunity to learn about this UNESCO World Heritage site and discover its rich history and culture at Base 11/19.

Beautiful panoramic view of Lens and the surrounding area. Be careful when you climb onto the spoil heap during a storm, it's a real hair-raiser!
