Paris to Grenoble and back cheapest way?

Question

Good evening,

Three of us are traveling from Paris to Grenoble from 4/28-4/30. What is the cheapest way to get to and from the place? Any help is appreciated :)

Answer 1

The cheapest is by bus, but it's long. If you take the TGV (train), it will cost approximatly $70, but you'll be there in 3 hours. I'm from Grenoble, if you have any questions [e-mail]

Answer 2

On 4/28 there is a train leaving at 08h34 from Gare de Lyon and arriving in Grenoble at 11h34. Price is 46.Euros

On 4/30 there is a train leaving at 13h15 from Grenoble and arriving in Paris at 16h55. Price is 52.70 euros.

To get these prices you need to book as soon as possible.
