Paris is the capital of France. Like nearly every big city, it's difficult to hitchhike out of it. Paris is even more difficult, since the ring highway (periferique) is relatively small.
Take RER B to Stade de France and after walking a while you'll find a final traffic light where you can ask for the first gas-station on the motorway (around 2 km away and NOT accessible from outside of the motorway)
First gas stationEdit
The first gas station is close to RER A station Bussy St. Georges. From there you walk south for about 1 km (you can ask at the counter) along a bigger road, which will lead you to a roundabout. You can try from there, but the gas station is just a bit more than 2 km from there. You can walk on the grass field next to the high way.
The Péage is not far from there, though it might be further than the closest highway exit...
Porte d'Orleans, at the periferiqueseems okay, Metro Porte d'Orleans. There's a gas station, and a good spot at the traffic junction to the "perfiferique exterieur". Don't go with cars going into the suburbs. The next tollway or gas station takes about 50 km! Porte d'italie, metro by same name, is a much nicer place to try to hitch. I couldn't ind a good spot at d'orleans and spend a whole day there without getting picked up..
