Portugal

Portugal's train service has contracted in the last decade, but it's still comprehensive and will connect you to most points in the country.

It's a great way to kick back and see the scenic beauty that defines Portugal's countryside without having to worry about worrying about following driving directions. The train route through the Douro Valley—the Linha do Douro—is especially beautiful, and often gets cited as one of the world's train trips that simply can't be missed.
