Day one is a 29 km walk to Berrias-Casteljau. Leaving Villefort, heading east, and walking through the high Cevennes for about 15 kms you arrive literally at the edge of the Rhone Valley (could be views across to the Alps) before heading downhill steeply to Les Vans (22 kms). Les Vans, which is the southern gateway the Parc Naturel Regional de Mont D'Archeche, looks great and has plenty of accommodation but in the interests of pushing on I plan to go a bit further. Shortly after Les Vans (now tracking the GR 4) you start to follow to course of the Gorge d'Ardeche and Berrias-Casteljau is located close to it.

It should be possible to make Chateaneuf-du-Rhone on Day 4. It's at least 33 kms but the countryside is fairly gentle with 700 metres of climb and descent. If time is not pressing than Saint Montan would be a great place to stay after about 20 kms.
