Oogle,
I would seriously make sure all the ducks are in a row before you venture in there.
People used to just pitch up into the paddock behind which is privately owned after "greasing a few wheels" and doing a drop and dash before you get nabbed by someone. It could be done because the traffic is so bad no official could get there inside 30 mins! The spot is unprepared and you could easily do some serious engine damage.
St Tropez is a nightmare unless you know somebody with a licensed private pad. And of course those in the know with that amount of coin have one!
Pilon near the old port in St Trop was closed years ago by the mayor of St Tropez who happens to be friends with the mayor of Grimaud, and there are problems of course in Cogolin, Ramatuelle, Gassin etc.
Even the airport at La Mole gets grief from these people and it is miles away.
The organiser of the "Halte Helico" association is Jean-Claude Molho.

The thing to be aware of is if you just arrive unannounced you will incur the wraith of the local operators as well.
Talk to Daniel at Heli-Securite at Grimaud +33494433930. Nice guy and very pragmatic about the whole thing. Even using Grimaud can be difficult and you are still 30 mins drive away on a good day. The locals all ride scooters for a reason!
Just park the boat off Pampelonne and stick them in a tender!
