1. Buy the ticket for hop on hop off bus : We traveled to all of these places through the hop on hop off bus. It was very convenient and covers all major tourist spots of the city in a systematic order.
2.Buy tickets for Casa Batlló, La Sagrada Familia, Camp nou and The Picasso Museum in advance : We bought these tickets the day we arrived in Barcelona along with hop on hop off bus tickets from the tourist information center in Placa de Catalunya (the center). You can buy them online as well or visit the nearest tourist information center.
You don’t want to wait in long lines for hours and you might even save some euros on your purchase of tickets in advance!
3. Barcelona pass or Barcelona card:Both the cards offer some discounts on attractions but I would suggest you to first decide on what places you want to visit and then consider buying any of these cards.
We did not purchase any of these cards. We only purchased the admission tickets to attractions and hop on hop off bus tickets which was more suitable and economical for us.
4. Enjoy discount on Student ID: If you’re a student, carry your Student ID which will save you at least €5 or more on entrance tickets at many attractions.
