Those with a dislike of tarmac might want to give this a miss, but they’ll be missing out on a lovely stretch through the woods between La Treille and Darenne. That said, the small tarmac roads are quiet and surrounded by nature.
At the moment, due to roadworks, a short section after La Treille is being used as a diversion and is slightly busier. The point (4) is just before (rather than just after) the chicken coop. There are lovely views over the Valdaine plain after this point. A walk recommended for those who cannot manage too much of an uphill climb.
