Orienteering is an original activity to do with family or friends, for fun or competition. In jeans and shoes or in training and trainers.

After a briefing, go in search of the numbered markers (or "posts") spread over the site of the former colliery and the three neighbouring slag heaps with the help of a map. The codes written on these markers allow you to solve a riddle and discover the treasure.

A good opportunity to come or return to the Bois du Cazier, a UNESCO World Heritage Site.
