Very nice peat marsh, refuge of rare species with a small fishing lake. The place is very friendly, wheelchair accessible and the lake has a fishing pontoon fitted out for wheelchairs

Quiet road but in poor condition on some sections (lots of gravel and potholes). I do not recommend for those who want to speed on a road bike. More of a path for a Sunday family walk.
