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!

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.
