Is there a Eurail Pass for Great Britain?
No, Eurail Passes aren't valid for train travel in Great Britain (England, Wales, and Scotland). The Eurail Global Pass and the Eurail Ireland Pass are valid in Northern Ireland as well as the Republic of Ireland. A Eurail Select Pass can also include Ireland.
If you have a Eurail Global Pass or a Eurail Pass valid in the Benelux (Belgium, Netherlands and Luxembourg), France or Ireland, discounts are available on certain ferry crossings to and from Great Britain. Your Eurail Pass also covers you for travel on high-speed Eurostar trains between London and Paris/Brussels.
