I am planning a trip in late April to France and trying to figure out where I can take the TGV to Paris from. Does anyone know if I can take it from Narbonne? Thanks for any help!
Yes, there are TGVs that go directly from Narbonne to Paris. For certain departure times you can take a regional train from Narbonne to Montpellier and a TGV from there to Paris. See the detailed timetables on the German Rail site.
The station that trains from Narbonne arrive in at Paris is at Gare de Lyon.
I am aware of three places in southern France that have 1-stop very fast trains into Paris. Marseille, Montpellier and Avignon TGV. The runs from Avignon TGV can be 2hrs39min. The other two are a bit farther away and take another 30-40 minutes longer.
Here is a rather picky map of the SNCF TGV system showing plenty of stations in the south. http://www.bonjourlafrance.com/france-trains/tgv-paris/schedules/tgv-paris.htm#DESTINATION
