rampage open air is a multi-day outdoor drum and bass and dubstep festival held at a park site in the belgian province of limburg. the rampage brand traces back to 2009, when it started as a club night series at a 1000-capacity venue in antwerp before scaling up to its current open-air format. the 2026 edition runs across eight stages, including a new giant main stage, a stage in a wooded area, and a dome stage, with over 300 artists on the bill.

the festival runs for several days and nights with camping, and travel packages are available for those coming from outside the region. rampage has grown into one of europe's flagship bass music events, with a separate indoor winter edition also running annually under the same brand.
