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!

This oak, 200 to 300 years old, would have been used by the German army during the First World War as an observation post. The panel states: "The soldiers could thus observe the artillery and enemy movements. We can still observe some of the iron bars which would have been inserted into the trunk in order to constitute a ladder. The tree having continued to grow, the majority of the bars have been absorbed by the bark."

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.

Difficult to drive on the site at this time because of the "luxuriant" vegetation. Access to the karting level is blocked by padlocked gates.
