I'm looking for a map that shows more detail than my road atlas of France. I want one that covers both the Millau area and up the Tarn Gorges. The only one I can find in England (Michelin) has Millau on the right edge and doesn't show the Tarn Gorge to the east and north. Will I be able to buy a suitable one once I arrive? Or can you give me a lead to one I can order in England, please?
