From london to nice about 1 3/4hrs. We usually get a taxi as the trains, buses etc are a nightmare, you never know when their running, IF there running. We got stuck for 3 hrs waiting for a bus only to find it wasnt running at all and we had to walk miles. If you can afford a taxi which is about 250.00 euros return a car its well worth it. If you havent been before its wonderful, but be warned, a cup of coffee on st tropez front is around 4.00 in our money, its not a cheap holiday, but i love it. So make sure you take everything you need, its not like spain where you buy all your toiletries out there to save weight, then throw whats left away before you come back.
