How to Plan a Stress-Free Interrail or Eurail Train Trip Around Europe

This page may contain affiliate links. Please read our disclosure for more info.

The best way to travel Europe is by train. It may not be the cheapest (flight prices can be ridiculously low), but it’s the most comfortable, relaxing, and easiest. There’s no need for the endless queuing like in airports, and most train stations are in the heart of the city. And you can enjoy the views along the way.

In September we did our third trip with an Interrail pass, which allows you to hop on trains all over the continent. We travelled from London to southern Spain via France, Switzerland, and Italy.

Our first Interrail trip was when we were newbie backpackers aged 19 and visited 10 countries in a month, and the second was three years ago when we travelled from London to Sicily via France, Germany, Slovenia and Italy.

We loved each of our Interrail experiences, and despite travelling at a faster pace than we usually do these days, we find train travel much less tiring than flying.

Below you’ll find our Interrail planner with tips to help you plan the perfect train trip in Europe. If you are wondering how to plan interrailing then this is the post for you.

What is an Interrail/ Eurail Pass?

An Interrail Global Pass is a rail pass that allows you to travel on most trains in 30 countries in Europe. Although you need seat reservations for some trains (I’ll cover that below), you can hop on and off many trains without having to buy a ticket. It makes European train travel easy and often saves you money.

You can buy passes for various time periods, such as seven days of travel within one month, 15 days continuous, or one month continuous, which is the pass we’ve always used.

Interrail also has one country passes for individual countries, but the Global Pass is the most popular and best value.

Interrail passes are for European residents. Everyone else can travel with a Eurail pass instead. These are similar but have slightly different time periods available—there are passes for up to three months continuous.

How to Buy an Interrail/ Eurail Pass

Interrail trip finished in Lubrin, Spain

Our final stop on our latest Interrail trip was Lubrin, Spain. Here’s us with our completed passes.

You can buy passes online from Interrail.eu or Eurail.com and get them delivered to your home. You must buy them before you start your trip. There are often discounts if you buy them in the winter or early spring. 

Prices vary depending on the length of the pass and your age. It’s cheaper if you are aged 27 or under and choose 2nd class.

If you are on a budget, 2nd class is totally fine. We love travelling first class, but mostly that’s because we work as we travel and first class carriages are quieter and more likely to have tables and power points. In many cases (especially on slower regional trains) the difference between first and second class isn’t huge.

Sample prices (with the current 15% off discount) are £395 / €434 for a one month continuous Interrail Global Pass for under 27-year-olds or £493/ €541 for the same pass if you are over 27.

See all the price options on the Interrail or Eurail websites. 

You can order a pass up to 11 months before your trip starts. For Interrail passes, your start date will be printed on your pass. For Eurail passes, you don’t need to choose a start date, but you must activate the pass before your trip starts at a European train station or online.

Is an Interrail Pass Worth it?

Whether a rail pass is worth it depends on the trip you want to take. If you’ll only be taking a few trains within one or two countries, it probably won’t be good value. If you want to cover a lot of ground, it could well save you money, especially in expensive Western European and Scandinavian countries.

I recommend coming up with a rough itinerary and using a site like Loco2 to calculate how much it would cost to buy tickets individually, then compare that to the price of the pass. If the cost is roughly the same, go with the pass as it’s so much easier not having to buy tickets for every trip.

Note that European train tickets are usually a lot cheaper if you buy a few months in advance rather than last minute. If you don’t want to commit to plans in advance, then a pass will give you the most flexibility.

Bear in mind that some countries are better for Interrailing than others. France, Spain and Italy require the most seat reservations (which you have to pay extra for), so a trip entirely to those countries might not work out good value.

The easiest countries for Interrailing are Belgium, Luxembourg, Netherlands, Switzerland, Germany, Austria, Denmark, Great Britain, and Ireland as most trains don’t require reservations, even high-speed ones.

Planning Your Interrail Route

The first step to Interrail planning is ask yourself: “Where have I always wanted to visit in Europe?”

I keep a wish list of places I want to visit, so I consulted that to plan my Interrail trip. I added the places I most wanted to go to a custom Google map, which allowed me to see which places could easily be combined and the best route to take.

A paper map comes with your pass or you can download the Europe train map to start mapping out routes. 

For Interrail route ideas, you could look at destinations on Pinterest, read travel blogs, or see these suggested Eurail itineraries

For variety, I suggest mixing beaches with cities and countryside. Combine famous destinations like Paris and Barcelona with less well known smaller towns like Colmar, Finale Ligure, Spello, Ljubljana, and Ghent.

Getting off the beaten track will help you avoid the crowds, save money on accommodation, and have a unique experience. You can also avoid seat reservations by doing shorter journeys on regional trains rather than long trips between big cities.

Once I had chosen some possible destinations, I used the online Interrail Train Timetable or Rail Planner app to see how long the train trips would be. At this point, I realised that I was trying to fit too much into a month, so I removed some countries and came up with a more realistic schedule.

The Interrail Train Timetable was really useful throughout our trip for looking up train times. You can choose to search for trains that don’t require reservations (just tick the box). This was especially helpful for us in Italy, and we managed to avoid paying for seat reservations for all but one train we took there. The app is free and works offline.

Rail passes do now include the Eurostar train for travel between London and Paris or Brussels (this is a recent change), which is fantastic if you are starting your trip in the UK or want to visit during your trip. Seat reservations are essential and should be made at least three months in advance, so it’s a good idea to plan your Interrail trip as far ahead as possible. 

The Eurostar is definitely the best way to travel between England and mainland Europe—it’s comfortable and only takes a few hours.  

Pass holders also receive discounts on some ferry routes such as between Italy and Greece.

Note that Interrail Global Passes are only valid for one outbound and one inbound train in your home country.

How to Make Interrail Seat Reservations

Italy to London by train: Perugia to Florence

Seat reservations are necessary on some high-speed trains and can be quite pricey. You can avoid them by using the Interrail Train Timetable or app to find trains that don’t require reservations.

We only needed five seat reservations out of the 23 journeys we took using our last rail pass, despite the fact that our trip was in the countries that require the most reservations—France, Italy and Spain.

Sometimes you want to take the quickest and most convenient train, though, especially for long journeys. Sleeper trains always require reservations.

Reservations can be made up to three months in advance. Seats for pass holders are limited on certain trains like the French TGVs, so it’s best to book as far in advance as possible in the summer. In late August/September, we booked a week or two in advance and had no problems.

How to make Interrail reservations depends on the country. You can book in person at train stations around Europe, but we couldn’t be bothered to do that during our trip, and as we were travelling in high season, we wanted to book in advance.

France

In France, we booked online at en.voyages-sncf.com. Just search for the train you want to take and choose Pass Interrail (Global Pass or One Country France) from the drop down list of discount cards. You can then print the e-ticket or save it on your mobile with their app (which is what we did).

Italy

In Italy, you can book online at trenitalia.com. Use the journey planner as normal (make sure you use Italian place names—Firenze not Florence, etc.) and click on the train you want to book.

You’ll be given a list of price options and you need to click on the grey box below them that says “View other options”.

On the next page choose Global Pass from the Offer drop down list. You can then go ahead and book. You don’t need to print an e-ticket, just show the PNR number on the train.

Interrail Reservations Service

Some countries, like Spain, don’t allow you to book seat reservations online, so we used the Interrail Reservations Service (Eurail also has this service). You do have to pay a €8 booking fee (total cost per train no matter how many seats you book) in addition to the reservation fee, but it was worth it for us.

The service was easy to use. We filled in the details online, and they confirmed our reservations within 24 hours and posted the tickets to our hotel in Italy within a week. They deliver anywhere in Europe for free.

Some trains (like Spanish domestic trains) have e-tickets so they don’t need to be posted (and the booking fee is only €6). 

Seat Reservation Costs

The Interrail site lists seat reservation fees. Most of our seat reservations were €9–10 each and cost the same for first or second class.

Our most expensive trip was the eight-hour journey from Marseille, France to Madrid, Spain. The seat reservation was €48 each in first class (€34 in second), plus the €8 booking fee for using the Reservations Service as we couldn’t book that train online.

Although this seems very expensive, the same train in second class would cost over €200 without a rail pass. If we had had more time, we could have avoided reservation fees by breaking up the journey in Barcelona and taking slower trains.

The Interrail timetable suggests this route to avoid reservation fees.

I recommend making seat reservations for a few major routes near the beginning of your trip, and keeping the rest of your trip flexible so you can hop on and off as you please.

Using Your Interrail Pass

An Interrail pass is easy to use. Before boarding a train, just record the trip details in the Travel Diary that is provided with your ticket.

If you have a flexi pass (such as 10 days of travel within one month), fill in the date of each travel day in the travel calendar, which is printed on your pass.

You can save travel days by taking night trains. If your train leaves after 7pm and arrives after 4am the next day, you only have to fill in the arrival day in the travel calendar.

Accommodation While Interrailing 

In high season (mainly the summer) you’ll need to book accommodation at least a few days in advance. We preferred booking in advance so that we didn’t have to look around for a place once we arrived.

If you are only spending a night in a city, choose accommodation near the train station to save time and hassle.

We use Booking.com for hostels, guesthouses, and hotels and Airbnb for rooms and apartments. Airbnb is often excellent value in Europe and you can save money by cooking for yourself. If you haven’t used it before, sign up here for $35/£25 off your first stay.
