What is Interrail?

Let me just get one thing out of the way. There is no difference between Eurail and Interrail. It’s called Eurail for non-Europeans, and Interrail for Europeans. There’s a difference in the name, not the concept.

Now, the big question. What is Interrail?

Interrail is a company that sells train passes for traveling through Europe. This company encourages (especially) young adults to go out and see Europe in a green and inexpensive way.

There are many reasons why you should go interrailing, like:

  • In Europe, there’s a huge train network. So why not use it, right?
  • It’s much more eco-friendly than planes or cars.
  • You will see a lot of beautiful scenery from the train.
  • You get to visit up to 33 European countries (depending on the pass you buy).
  • It’s a wonderful option for budget travel.
  • Interrailing is great for developing yourself.
  • You could make many new friends.
  • The Interrail pass is easy to use.
  • It’s a real adventure!

There are many benefits, which I hope encourage you to go interrailing. I’ve been interrailing once and it was quite the adventure!

Interrail passes

When buying an interrail pass, there are many different passes to choose from. This is so you can get the best price for your situation/plans.

You can choose to buy a pass with travel days, a continuous pass, or a one-country pass. All these passes are different in both what you can do with them and their prices.

All these passes range from 100 to 700 euros. This means you can buy a pass that fits your budget.

Read more about interrail passes and which one’s best for you.


Of course, to get from place to place you will use your Interrail pass. But how to get to the first place and how to get home? This depends on your starting point.

If the starting point is less than a 10-hour train ride, you should use your Interrail pass. This will be the cheapest. But if you live a long way from your starting point, flying there may be your best option.

Best Interrail routes 3 weeks

In the itineraries I made, the starting point won’t be the same as the finish, so look carefully at which option is best for you, depending on the itinerary you choose.

And of course, during your trip, you’ll need transportation other than trains, for day trips and such. Most countries have a good bus network and you can (and should) book some day trips that include transport.

Getting around in a city should be easy, you can walk to most places and take buses, trams, or metros to further away places.

Best Interrail routes for 3 weeks in Europe

Because everyone’s different and likes to see other things, I’ve made 2 itineraries through different regions of Europe. Someone who’d love to see Paris may have no business in Belgrade and someone who’d love to visit Oslo may not be looking for a beach vacation in Malaga.

So I’ve put together 2 different itineraries:

Interrail route 1: Interrailing on a budget

Prague – Krakow – Bratislava – Budapest – Belgrade – Mostar – Zadar – Ljublana

Interrail route 2: Admire the big cities itinerary

London – Paris – Barcelona – Nice – Milan – Venice – Munich – Antwerp – Amsterdam

Best Interrail routes for 3 weeks in Europe

Route 1: Interrailing on a budget

Prague – Krakow – Bratislava – Budapest – Belgrade – Mostar – Zadar – Ljublana

Interrail is a super popular option for people traveling Europe on a budget. As a ticket is relatively cheap for everything you can do with it, people often go for this option.

My favorite part of Europe is also the cheapest part to travel to. We’re talking about eastern Europe. With a huge history, gothic-like structures, breathtaking nature, and the best cultures, eastern Europe is a place you simply must visit!

So I’ve made this itinerary (my number one) for those wanting to visit the most beautiful places on a small budget and dodge the crowded and more expensive cities.

Budget: For this itinerary, your budget should be around €30 a day per person.

Note: If you want to take some day trips, I highly recommend booking them through Tripadvisor. This trustworthy company will bring you experiences never to forget!
