How can I travel to and from London?
Eurail Passes aren't valid in Great Britain (England, Scotland, and Wales). However, your pass entitles you to travel to London with the Eurostar high-speed train. Departing from Brussels or Paris, the Eurostar travels under the sea through the Channel Tunnel. A seat reservation is compulsory.
You can also travel with Stena Line Ferries between Hoek van Holland (Netherlands) and Harwich (England). Eurail Pass holders get a 30% discount on this crossing.
