2 days in Barcelona. Best way to get around and things to do.
Take one of the Hop-on Hop-off buses to see the main sights...Sagrada Familia cathedral, Parc Guell, etc. Spend a day walking the Barceloneta Beach, visit the Gothic quarter, walk the famous Las Ramblas and eat tapas and drink sangria!
Walk, drink and eat!!
The metro is easy to use. Wait this should be in another section.
Victor, this is the Italy section of the RS board.
