I've visited over 50 European cities. Here are the 5 I can't wait to return to.

Barcelona is, dare I say, my favorite city in the world. Its unique architecture is reason enough to visit, but Spain also offers some of the best cuisine around.

Barcelona truly offers something for everyone, from parks and beaches to nightclubs and cafés.

When I visited Bunkers del Carmel, a popular lookout spot that provides stunning views of Barcelona, I felt a true sense of community. Here, I found people simply drinking wine and enjoying the views together.

I've found that Porto is often overlooked for Portugal's more popular city, Lisbon. When I visited Porto, however, I spent my days sitting by the waterfront, drinking port wine, and eating amazing Portuguese food.

Seeing the sunset here is a right of passage — I recommend catching one at Jardim do Morro, a garden overlooking the city.

When I visited Edinburgh, I felt like I was on the set of a Harry Potter film. The medieval architecture is unlike anything I've seen before, and it's easy to explore the city on foot.

The food scene did not disappoint, and I learned that Scottish cuisine is much more than just haggis. I recommend checking out restaurants like Oink and The Bon Vivant.

Ljubljana, Slovenia, is one of the most aesthetically-pleasing cities I've visited. Its natural beauty is unmatched, and it's very easy to get around from the city center.

In my opinion, a trip to Ljubljana isn't complete without a visit to Lake Bled, where travelers can enjoy turquoise waters and gorgeous mountains.

The city also has an award-winning food scene, with multiple Michelin stars to show for it.

Colmar, located in the Alsace region of France, feels like a Disney movie come to life. I've visited the famous Christmas markets in the region, but the area has so much to offer.

Aside from Christmas festivities, Alsace is also known for its wine. In my opinion, the Alsace wine route is an underrated travel destination, as it's often outshined by more popular areas like Paris and the South of France.

Whether it's your first or fifth time in France, I recommend adding Colmar to your list of cities to visit.
