Try the Eurostar website. They will show connections to all places in France

Hi our family took the TGV from Paris Charles du galle airport to Avignon last August with our two children aged 8 and 9. We loved the fast train it was great way to see france and quite resonably priced we booked through http://www.sncf.co.uk.

many thanks for your replies, when you booked online did it give the option to add children as passengers. I tried going onto it today and it would only allow me to add adult passengers. How far in advance did you book the tickets and did you manage to get the best prices?

I booked about 2 months in advance I think there is a limit on how far in advance you can book. I definately booked the children in at about half adult price, as I remember it was near the end of the booking process they ask for ages of passengers.
Hope that makes sense

Thanks Lizzie. I also came across a french based website, which seems to be cheaper than the rail europe or SNCF sites: I can not add the link as I have not posted enough posts, but do a search for voyages-sncf. May be useful if plan to go again by train. I'll try later this month to make the booking.

Hopefully here is the link you found Asiagirl.
