I visited 13 major European cities in 6 months. Here are 2 I can’t wait to visit again and 2 I probably won’t return to.

If you’re looking for a truly medieval-feeling city in the UK, you can’t choose a better spot than the Scottish capital, Edinburgh.

I was mesmerized by the city’s stunning mix of architectural styles, which makes the buildings appear larger than life. Most notably, Edinburgh Castle towers over the city and is visible from many different spots in town.

Edinburgh is also a treasure trove of history, whether it’s Mary King’s Close, a preserved 17th-century alley, or a whiskey tour in which I learned about the distinctive regional varieties of Scotch.

When the colder weather started getting to me, I was able to find a surprising number of hot-chocolate shops. I found that hot cocoa paired with a doughnut from one of the countless bakeries around town made for the perfect afternoon snack.

Amsterdam has a reputation as a party city, particularly its proclivity for marijuana and the Red Light District. Though Amsterdam is definitely a good place to have a great time, there is so much more to the city.

During my stay, I tried to avoid the tourist hot spots, favoring the local neighborhoods instead. One particularly enchanting walk along the canals led me to Foodhallen, a lively food market where I got to enjoy sushi, a corndog, and the Dutch snack of bitterballen — which can best be described as a deep-fried stew ball.

When I did venture to busier places, it was to tour the art and history museums. My favorites were the Van Gogh Museum and the Anne Frank House, which were each powerful and moving in their own right.

I also enjoyed how much the city’s layout differed from the other European cities I visited. Bikes and boats reign supreme, which make for lovely ways to explore the city.

Zurich is a gorgeous city, and sitting on the banks of the lake with a plate of currywurst was a top-tier European experience for me.

Though I found the city to be expensive compared with the other places I visited, the main reason I wouldn’t return is because of Zurich’s enviable neighbors: the villages of the Swiss Alps.

In just a few hours, you can leave the urban environment and arrive in towns like Wengen and Mürren, which look straight out of a storybook.

One of the main reasons I wanted to visit the capital of Wales was to tour Cardiff Castle, and the complex didn’t disappoint. I learned about 2,000 years of history, from ancient ruling families to an underground bunker used in World War II.

But in my opinion, the rest of Cardiff wasn’t quite as impressive.

Though I enjoyed the Victorian and Edwardian arcades (glass-roofed alleys with various shops), the city center felt a bit grungier than the others I visited because of some loose trash lying around. I also felt as if there weren’t a ton of other activities to do in the vicinity.

But with 400 castles scattered throughout the country, I’ll be sure to explore the more remote parts of Wales on my next visit.
