Heitere Open Air

Heitere Open Air is held every summer on a hill above Zofingen, in the canton of Aargau, Switzerland, overlooking the town and the Wigger valley. Starting out with around 4,000 visitors, it has grown into one of Switzerland's best-known open-air festivals, running over three days since 1998. The lineup spans hip-hop, pop and EDM, alongside a Ferris wheel, a small market and activities for children.
