Strasbourg

Strasbourg is one of the bigger cities of France. It is the siege of the European Parliament, and pretty bourgeois.

In theory it seems doable to hitchhike directly from the centre, as there is the entrance to several highways. However, the people of the city are not very hitchhike-friendly, so it is better to directly go to a gas station on the highway.

For going north

Go south, taking a tram southwards (probably A), right to the end of the line. From there you walk west for a while, and then you can find the gas station on the side to go north.

For going east (Germany A5)

You can take the regional train going to Kehl which is already in Germany (around 6 minutes for 2-3 euros). In Kehl you've got a big road going directly to the motorway A5 - and everyone who's coming from France is using this road. You also find a gas station!

Also, to go from Stasbourg to Kehl, you can use the bus (line #21 ; one bus every 30 min). It's a bit longer but quite cheaper (1,30 euro instead of 3,50 for train) and it stops in several places from "Ancienne Douanne" to the east side of the city (usefull if you are in the eastern part of the city).

By train, for 2 euros more, you can continue after Kehl till Appenweier. From there you can walk or hitchhike to the gaz station "Rasthof Renchtal" (2,5km check the route on maps.google.com ). It can be a good alternative to Kehl because in 30 minutes more, you're on the german motorway network.

For going south

Take the tram (red line) to Illkirch Lixenbuhl and then the bus (line 2) to Ostwald Eglise. From there, walk towards the Nachtweid forest. A small road runs along its edge and leads to a gas station on the A35 motorway.
