To get around the city, it's recommended to use the public transportation such as the metro or bus. A T-10 travel card costs €10.20 and allows for ten journeys on any form of public transportation within the city zone. For activities outside the city, consider renting a car or booking tours.
If you have more time, consider visiting the beautiful beaches of Barcelona such as the Barceloneta or the Bogatell. You can also take a day trip to the charming city of Girona or the beautiful Costa Brava to enjoy more of Spain's natural beauty. If you have less time, you can skip the hot air balloon ride or the kayaking experience.
