The sleek, high speed Thalys trains offer a quick way to reach other European cities from Paris. It’s only 1½ hours to Brussels and 4 hours to Amsterdam, which make it competitive with a plane trip, since you must also spend more time going through airport security and travel from the outlying airports to the city center.
A round trip to/from Amsterdam is about €107 in second class. Other cities served include Rotterdam, Antwerp, Köln, Aachen and Geneva. The service is so fast and reliable that you’ll get a partial to full refund if your train arrives at least 31 minutes late.
There’s no meal service with Comfort 2 (second class), but there is a bar car with overpriced and barely edible food. Comfort 1, (first class) offers snacks and a light meal on longer journeys depending upon the time of day. First class is more comfortable, and probably worth the extra money on a long haul.
