Barcelona has many iconic landmarks like the Sagrada Família, Park Güell, and La Rambla. These attractions are must-sees with their beautiful architecture and rich history. However, their popularity often means they are crowded, and securing tickets can be challenging. If you're not a fan of popular tourist spots or simply can't get tickets, don't worry—Barcelona has so much more to offer.

Venture off the main path. Not only will you be able to engage with the locals more, but you will also discover serene and picturesque spots that not many people visit. If you want beautiful Instagram photos, especially if you are socially anxious, these spots are perfect for you.

Remember to always be respectful. Keep in mind that people live in Barcelona and don't want loud tourists everywhere. When you visit less popular spots, don't make it all about yourself.
