We travelled same route as previous entry from David Klyne, via auto route. Stopped off at excellent site, Camping Les Breuils, at Verdun and again at a municipal at Selestat, both just off autoroute. Despite reservations by others about using this route we have never experienced problems. No mountain passes. The first time we entered via Basle there were roadworks which caused some delay through the border, but that could occur anywhere. We're going again in July to Lazy Rancho - excellent facilities and perfect area.
