Open'er Festival 2026 Brings International Headliners to Gdynia in July
Poland's largest music festival runs July 1-4 at Gdynia-Kosakowo Airport with Calvin Harris, The Cure, and Florence + The Machine headlining. Over 100,000 attendees expected, with 20% from abroad.
Open'er Festival 2026 will take place from July 1-4 at the Gdynia-Kosakowo Airport on Poland's Baltic coast, drawing over 100,000 music fans from across Europe and beyond. The four-day event is Poland's biggest music festival and one of Europe's most internationally recognized summer gatherings, with approximately one in five attendees coming from abroad.
Headliners and Logistics
The 2026 lineup features major international acts including Calvin Harris, The Cure, Halsey, Florence + The Machine, The xx, Martin Garrix, Nick Cave and The Bad Seeds, PinkPantheress, and Teddy Swims. Polish artists including Vito Bambino, Sobel, and Łaszewo will also perform across multiple stages. The festival grounds occupy a former military airport, creating what organizers describe as a unique atmosphere for both intimate performances and large-scale main stage productions.
Special shuttle buses run continuously between the festival site and Gdynia and Gdańsk city centers, with late-night services departing until 3-4am after headline acts finish. On-site camping is available directly at the festival grounds, and many international visitors stay in hotels or hostels in Gdynia or neighboring Gdańsk.
Practical Information for Foreign Residents
Tickets cost approximately 500 PLN or more for the full four-day pass. The festival app provides real-time notifications for favorite bands, stage schedules, and site maps in multiple languages including English and Polish. If you're planning to attend, book accommodation early as hotels along the Baltic coast fill up quickly during this popular long weekend. Public transport connections from Warsaw, Kraków, and other major cities to Gdynia are frequent, with the festival coinciding with Poland's summer holiday season when many Poles take extended breaks.
