Three days in Aix-en-Provence was too long – won’t be going back there for a while. Took the road north and got lost , but found a supermarket open and topped up on food and wine. Sunday morning supermarkets in France are pretty busy and to be avoided if possible.
Drove north to Sisteron to the (rather excellent) municipal campsite there. Only planned to stop for the night, but will stay for two as this is an interesting place with spectacular scenery. However, internet access here costs money and is not so good.
