The Outsider saw the light of day in 1987, deep in the Ardennes. At a time when outdoor sports did not yet have a permanent place in Belgium, we put on our bottoms and went for it.
After the expansion of The Outsider Ardennes and – 10 years later – The Outsider Coast, in 2007 we settled down at the Donkvijver in Oudenaarde for The Outsider Flemish Ardennes. In 2026, we settled at the fortress of Chaudfontaine for the start of The Outsider Chaudfontaine.
What started as an old overgrown war fort grew into a fantastic adventure park where team building, outdoor fun and vacation spirit are never far away.
We are pioneers in outdoor experiences, and proud of it!
