INmusic Festival 2025

Perhaps the only music festival in the world that runs from Monday to Wednesday, Croatia's largest open-air fest straddles two national holidays. It may not be on the beach, but INmusic boasts a sweet lakeside venue with camping on Youth Island in Zagreb. The international lineup always features huge acts (some of them playing Croatia for the first time) like Florence+the Machine, Arctic Monkeys, Pixies, Arcade Fire, New Order, and Billy Idol.
