Do I need a reservation?
When traveling with a Eurail Pass, it’s good to know which trains need to be reserved in advance. As a general rule, reservations are required for all European night trains and most high-speed trains.
In popular countries like France, Spain, and Italy, most Eurail travelers will need to make a seat reservation at least once. If you're traveling in high season, from June until September, we recommend that you make reservations early to save your seat!
