We are going to S of F this year too. Three small trailable cruisers and their families.
We had a weekend out there in Feb to try and get some info on launching and this is what we found if any use.
Slipway at Cavalaire is public but unlike our slipways it only goes back a few feet and then a sheer drop off the end!! although it will be OK to launch and recover our 23 foot boats so should be OK for you. Parking for car and trailer there is in the sports stadium in the town.No charge but cannot book and no security and no guarantee it won't be full!!
Good slip at Ste Maxime but directly off the main road thorough town.This was the only town that was busy in Feb so goodness knows what it's like in August!! We deceded arriving with three 23 foot boats was just too risky but one boat may be OK as there was a small parking space you could pull into before launching.Again car and trailer parking a bit of a problem there.
Slip at St Raphael marina good slip again similar to Cavalaire.Boat yard couldn't agree parking with us then but said to contact them later on.Have done that and they have never replied!! even though letter written in french!
Travelled the whole length of that coast and only found those slipways that were open to the public.others were for the boat owners moored in the marinas.
After many web searches found car and trailer parking at Cogolin 10 miles inland of Cavalaire. Car and trailer stored under cover for 2 weeks in July/August with security guard on site for £58. Not open Saturday pm and Sunday Address is
