Barcelona has an extensive public transportation system that is efficient and easy to use. The city has a well-connected metro system, buses, and trains that offer a variety of options for getting around. It is recommended to purchase a 10-ride ticket pack for the metro system in advance for a discount. Taxis and Ubers are also available but are more expensive than public transportation.
Travel time and costs will vary depending on the location and method of transportation chosen. Day trips to nearby towns such as Sitges require train fare, which can amount to €10-€15 per person.
If you have extra time, consider a day trip to the nearby towns of Girona or Tarragona, both of which are known for their beautiful architecture and rich cultural history. For travelers with fewer days, it is recommended to prioritize the Gothic Quarter, Sagrada Familia, and Park Güell for their cultural significance and unique architecture.
