Montjuïc is a Barcelona classic but really worth it. You can go by the “teleferico” which is more expensive (and a bit too short!) but fun. The view of Barcelona from there is breathtaking, and you can walk and see nice gardens and a the charming Montjuïc castle
El Nacional is one of the most beautiful food and drinks hall in Barcelona. You can wether sit at a table to have a proper diner or just have a drink and a tapa at the bar. You might have to go early, it is a busy place!
Nice big park in the heart of Barcelona. Napping at the shadow of the trees can feel like a fresh paradise during summer time!
Carrer de Blai is a pedestrian street in Barcelona, known as the tapas street. You will find tapas bar after tapas bar, with delicious local food 🥟 and drinks 🍻. Remember to go with an empty stomach!
