About us

Windwerk is the only indoor skydiving wind tunnel in German Switzerland and is therefore a one-of-a-kind sport and leisure attraction for the region. Learn more about us below.

The wind tunnel

Where people can fly.

The wind tunnel is based on a state-of-the-art facility belonging to the ISG Group (Indoor Skydiving Germany Group). ‘Made in Germany’ – or in other words: top quality, elegant design and maximum safety.

At 17 metres tall and with a diameter of 4.3 metres, the vertical wind tunnel is generously proportioned. It is also surrounded by glass: you always have a clear view in our wind tunnel. Even at wind speeds of 160 to 280 km/h. Four fans provide an even air flow and ensure optimum conditions for beginners and professionals alike.

Sustainability is also important to us: we use the waste heat generated for heating and hot water.
