Open'er Festival

About

Open'er is Poland's biggest ticketed festival, held on the Gdynia-Kosakowo Airfield just north of Gdynia on the Baltic coast from 30 June to 3 July 2027. Four days and nights of pop, hip-hop, rock and electronic music across multiple stages draw around 100,000 people, with on-site camping and a large programme of art, fashion and film alongside the music. Tame Impala are the first headliner announced for 2027. The site is about 20 km north of central Gdansk.
