Eurail passes are a MUST if you backpacking Europe. This is your chance to see the remarkable European landscapes like you’ve never seen before.
Habla español? If you’re traveling through Spain and aren’t in a huge rush, you just have to travel by train on at least one of your journeys. The Spanish countryside is beautiful and you won’t get to see that by plane.
Traveling by Eurail is fun, especially if you are traveling with someone else or even a group. You simply have more freedom and can walk about and just be goofier than you would be if you were traveling by plane.
