RealFly is the first Wind Tunnel in Switzerland.

Located at the foothills of the ski resorts and mountains in Sion, Valais!

It goes without saying that the WindTunnel has become the best place to train and improve in skydiving.
The “Tunnel” has also become more than a secondary discipline – it is a sport in its own right, with its codes and tribes, its stars and its gurus, its laughter and its tears.
At RealFly you will fly through a ”new generation” tunnel, a Strojirna-2014 at 14 metres high and 4.35 metres (14 feet) in diameter.
It’s big enough for the D4W, VR4, VR6 and more if agreed. The best in the world can be found here!
