If you intend to fly, Barcelona El Prat is the nearest international airport to the city, and it is just a short bus ride into the city centre.
The Parc del Fòrum is just a few km north of the city centre, and is accessible via Metro line 4 towards La Pau, exiting at El Maresme/Fòrum. The site is then just a 2 minute walk to the Parc del Fòrum.
Alternatively, bus numbers 43, 7, 36,141 and 41 pass by the festival site.
You must be at least 18 to attend.
