Gràcia Festival 2011
The Festa Major in Gràcia is arguably the best (but don’t say that to any residents of Sants who celebrate their festa from August 20th to 28th).
Up in Gràcia there are seven days of open-air concerts, competitions, balconies festooned and streets dressed up in (sometimes) astonishing decorations.
During the day, you can saunter round getting good views of the decorations, but at night it’s a totally different affair. Grab a beer from one of the many street-side stalls, join the crowds packed through the narrow streets and take in the party atmosphere.
See their website for full schedule of events.
