Long-distance and high-speed trains arrive in Paris at several different stations with Gare du Nord, Gare de l'Est, and Gare de Lyon amongst the more important ones for international travelers. Connecting between French long-distance trains going into the opposite direction from Paris, usually require a transfer to a different station as well. Taking a suburban RER train or the Metro is usually the fastest and cheapest way to make such a transfer although in some cases walking is easier while travelers with bulky luggage may find it worth splurging on a taxi.
Gare du Nord Station in Paris, France
Eurostar trains from London St Pancras International arrive in Paris at Gare du Nord (North Station), as do TGV Thalys trains from Northern France, Brussels, Amsterdam, and Cologne (Köln). Unfortunately, for most travelers Gare du Nord is not the final destination. Even travelers to Paris will generally require further transportation while those en route to other parts of France, Germany, Italy, Spain, or Switzerland will have to change to other major long-distance stations to catch further TGV trains.
