The Open Air Lumnezia is a Swiss open-air music festival in Grisons. It takes place every year on the second last weekend of July in the Val Lumnezia near Degen. The open air Lumnezia started as a small rock concert founded by the young Lumnezia team in Davos Munts near Vattiz in 1985.
Meanwhile, the Open Air has risen to become one of the largest in Switzerland. With over 18,000 visitors, it is a bit behind other festivals. Due to the limitation of the terrain size, the open air could not be extended. For this and other reasons, the Openair has been held in Degen since 2006.
