Europe is a super popular place to travel to in the spring and summer, and people even go in the winter if they want to see Christmas markets or if that's when they get some time off. Sure, you know the major cities that people say you absolutely have to see, from Paris to London to Rome, but there are a lot of other places that people don't talk about as much. And even within the most famous cities are certain sights and activities that will make your trip an unforgettable and magical experience.

Before you plan your trip to Europe, it's time to take a look at the destinations that absolutely have to be part of your journey.

Here's a travel guide to Europe: 20 places not to miss out on.
