ABOUT YONDERLAND

We are convinced that outside is exciting, relaxing and inspiring. It’s versatile, for some it is a place to relax, for others it is the ultimate challenge. A place to enjoy and where big and small moments come together. It’s a place to be discovered or to be recognized. But the outdoors can also be treacherous and unpredictable. Weather and terrain can surprise you. Our mission is to enable all people to spend inspiring and epic moments outside.

Yonderland is a European group of premium brands and retail concepts focused on outdoor. Including A.S. Adventure, JuMu, Bever, Cotswold, Snow+Rock, Runnersneed and Ayacucho. Yonderland runs over 190 shops in Belgium, Luxembourg, France, Great-Britain and The Netherlands and resides in Belgium. <endereço ocultado>
