Ouigo, the low-cost version of France’s TGV, has released 100,000 tickets for summer travel from the Paris region to the south: Avignon, Aix, Marseilles, Nice, etc.) at an eye-popping €10 each. Available on ouigo.com, but likely not for too long, at least for popular dates.

I took the Ouigo in 2013 from to Paris to Marseilles and I really enjoyed it. Here is some purchasing tips I learned at the time. Not sure how much has changed, hopefully someone can update us.
