A backpack is a hands-free option that lets you keep your belongings close to you at all times which in turn makes it easy to access your belongings on the go. The benefits of interrailing Europe with a backpack means you don't have to worry about leaving your luggage unattended or struggling to carry multiple bags.

Deciding between a backpack and a suitcase for an Interrail adventure depends largely on your itinerary and physical mobility. A backpack (specifically a 40–60 liter travel pack) is widely considered the "gold standard" for Interrailing because it offers maximum agility. You will frequently encounter cobblestone streets in Prague, narrow staircases in Parisian hostels, and the need to dash between platforms for tight train connections—scenarios where wheels often fail or break. However, a suitcase (hardshell or spinner) is superior if you have back issues or plan to stay in high-end hotels with elevators. In 2026, many rail stations have improved step-free access, but the "last mile" to your accommodation remains the challenge. If you choose a backpack, ensure it has a proper hip belt to transfer weight from your shoulders. If you opt for a suitcase, stick to a "carry-on" size; lifting a massive 20 kg trunk into the narrow overhead luggage racks of a high-speed train is a recipe for physical strain and frustration for both you and your fellow passengers.
