In reply to colin8ll: Just back from the Calanques. The easier routes are excellent. It is a long walk so prepare to enjoy all the scenery (which will be good every day) or get there very quickly by boat each day if you can budget that.
There is a little dew and rain now but that doesn't stop the rock drying quickly and the sea being warm but camping is off unless you have a car now I believe, the nearest site being 10 miles inland.
The walk in is worth it but 3 hours each way every day unless you're very fit, then 2 hours, as the routes are long and as good as they look. Calanque En Vau, the 3rd in from the East, is set to hold you for a fortnight.
