Transportation in France
Car
Carpooling :
With the coach, it is probably one of the cheapest means of transport to move from one town to another. You can create your account on https://www.blablacar.fr. You can also go on the facebook group « Covoiturage Agrocampus Ouest, Rennes »
Car renting :
Economical if you travel with others. There are several car rental agencies
in Rennes. For instance, you can go on : https://www.europcar.fr/,

It is cheap but a bit longer. There can be extra fees for luggage.
Websites : Ouibus : http://fr.ouibus.com/fr, Eurolines dans toute l'Europe : www.eurolines.fr, Atlassib : www.atlassib.ro, Flixbus : https://www.flixbus.fr
Plane
This means of transport is quite expensive but there are some low cost companies (easyjet, ryanair) and you can get good prices if you book a flight early. Several websites compare prices, pay attention to fees that are not necessary included in the price.
Train
There is only one national company to move from one city to antother. It is SNCF. You can get all the information online : www.voyage-sncf.com. It is quite expensive but if you travel a lot, you can get discount.
You can travel with OUIGO, which belongs to SNCF. It is a bit cheaper but there is less choice. Website : http://ouigo.com
Hitchhiking
It is allowed in France. Be careful of course!
