Saint-Ambroix is a village in France, on the route from Valence to Alès. It is easy to get a ride from here due to the lack of buses, which makes hitchiking more common and accepted.
Hitchhiking out
To Alés, Montpellier.
Go to the Lidl that is close to the end of the city. From there you can walk 10 minutes to a good spot where cars can stop, next to a dirt road called 'Chemin de Banassac'
