Open'er Festival

Open'er Festival runs from Wednesday to Saturday in late June or early July at the former Gdynia-Kosakowo airport near Poland's Baltic coast. Launched in Warsaw in 2002 as the Open Air Festival before relocating to Gdynia, it has grown into one of Poland's largest music festivals, spanning rock, pop, indie, dance and electronic acts across multiple stages. Its distinctive former-airfield setting and international line-ups have earned it repeated Best Major Festival honours at the European Festivals Awards.
