The bridge I jumped was about ½km to 1km down river. The nearest town is Vallon Pont D’Arc. To get there take the A7 South from Lyons, get off at the junction for Montellimar and head for Le Teil. Then head
for Viviers, Bourg St Andeol and finally Vallon Pont D’Arc. Follow signs to Le Pont D’Arc, park up then head downstream. Once you reach the bridge if you swim across the river you can climb up the bank on the other side (going under the bridge). Before you jump make sure you check the depth-it changes a lot depending on
the weather, also make sure you jump out far enough to avoid the submerged rocks! Safe jumping!
