Towpath alternating between tarmac and fine gravel, fairly smooth. Perfect for a family stroll.

Overall, the tour of the slag heap is very smooth, great for gravel and easily doable by mountain bike.

Most of the path is very smooth and you can enjoy the few birds and (rarely) the sun reflecting in the water. Unfortunately it is very often spoiled by the discharges from factories or sewers which often bring a foul smell, especially when the water is stirred up by the few barges that pass by.

The Hautois woods are a pleasant place for a walk, especially around its pond.

South of Carvin, a slag heap stands in a wooded environment where it is pleasant to cycle. Be careful, the paths can become muddy in case of rain.

Passage impossible due to vegetation. Air-soft session in the passage without signage. As a result I got shot and ultimately it was my fault...
