A 15 minute drive from La Ciotat is Cassis.
We visited here last year just to walk around and take a few photos of the waterfront. This year we hiked a bit into les Calanques. WE would like to sail here, but they are small and by the time the boat is ready, they will be crowded. So hiking them is a pleasant alternative.
Also, Cassis is an appellation, known for their whites and as rosés as well. Some of their reds are also pretty good, but nothing like the big boy reds of Burgandy and Bordeaux.
Anyway- the gelato is just fine!
