If you go to Barcelona, be sure to visit Park Güell.

I recommend Park Güell in Barcelona. Park Güell is a place that makes you feel like you've stepped into a fairy tale. It's a place where you can feel Gaudí's genius imagination. The colorful mosaic tiles and organic curves make it feel like you've entered a storybook from Hansel and Gretel! Especially if you go to the top of the park, you can see a panoramic view of Barcelona, so it's a must-visit place when you go to Barcelona:) Cons: Since it's a famous tourist spot, it can get quite crowded 🥹
