Carreau Valley redeveloped to highlight the mining heritage. The paths that were once dirt are now gravel, ideal for walking or cycling. Don't hesitate to go up to the terriloscope. By putting your eye at the level of the holes provided for this purpose you will see what the height of the slag heaps was in their heyday. This allows you to see the effects of time.
