Vitrolles, the train station for the airport, has two direct services to Toulon per day (€17, 1¼ hours), from where onward connections are plentiful. To get to other larger centres on Var's rail and bus network (Brignoles or Les Arcs Draguignan, for example) you'll need to take multiple trains, changing at Aix-en Provence and/or Marseille. Free shuttle buses leave from platform five of the airport's bus station for the five-minute trip to Vitrolles every 10 to 15 minutes.
Up to four buses per day run from bus platform 3 at Marseille Airport to Le Muy, 37km short of St-Tropez (€25, 3¾ hours). From late June to August, one or two of these buses continue all the way into St-Tropez from Friday to Monday. This line (36) also stops at Brignoles and Les Arcs Draguignan throughout the year, from where you can get other services within Var.
Car & Motorcycle
From Marseille airport, head east on the A7 and A50 towards Aubagne; stick on this autoroute if it's Var's coast you're heading for (expect to pay tolls of around €2 at a few points) or take the D560 if your destination is further inland. For the Haut-Var, take the A8 for as much of the trip from the airport as you can.
Toulon, Hyères, La Londe, Le Lavandou, St-Tropez and Port Grimaud are the major ports receiving commercial and pleasure-craft within Var. Hyères is the only marine port-of-entry in the département if you're crossing the French border.
