Train travel from Paris to Limoux

Two possible departure stations from Paris:

1/ Paris Montparnasse station : with two connections: first in Toulouse, second in Carcassonne

2/ Paris Gare de Lyon station: with two connections: first in Lyon, second in Carcassonne

Travel times are roughly the same for both (approximately 6 hours 30 minutes).

Route 2 is a bit more scenic than route 1 IMO.

When planning train travel it is actually not necessary to figure out which station you will leave from.

On www.sncf-connect.com (or most other trip planners) just choose "Paris" as origin, and let the system figure it out for you.
