We will be driving to Cassis from Aix. I have read posts on this forum and done a bit of research online. We will spend the morning in Cassis. In the afternoon, we will catch a boat to see the Calanques. We are particularly interested in doing some swimming in the Calanques. I've read in this forum and in other places and got the impression that it might be too cold to swim in June. Is that true?
After reading guidebooks, forum posts, and online posts, I am still unsure about the boat arrangement. Most of the posts are about boats to see les Calanques (but not swimming, at least to my impression). I did see one company offering the opportunity for swimming, but the boats depart from Marseille. I think there must be boats from Cassis that offer an opportunity to swim in the les calanques.
Please advise. Many thanks in advance.
