Uzes to pont du Gard on bike.
We found this newly built (2018) old railway line which is impeccably flat and got really good tarmac. It's 12 Kms long and you can continue to Beaucaire alongside the Gardon. The route takes you through car park where you pay 18 euros for pont du Gard but it's a voit vert so free for pushbike...
