Free events all year
Barcelona's cultural calendar has a strong free tier; time the trip right and the city entertains you for nothing.
Llum BCN
Every February, light artists take over Poblenou for several nights of installations and projections, all of it open air and free.
BAM
The Barcelona Acció Musical programme puts free stages across the city during La Mercè, big names in small squares.
Sant Joan
Midsummer night turns the beaches into a free party of bonfires, cava and fireworks; arrive before dark if you want a spot.
