Even more sport on and in the water Real water lovers never get enough of the cool water. In Malente, in the middle of the Holstein Switzerland holiday region, you can experience water sports in all their variety. If you like cycling, you could, for example, set off on a pedal boat across the Dieksee. In the calm waters of the lake district, even beginners can try diving and learn easily. The Schwentine, with its romantically overgrown banks and pretty villas, is ideal for trying stand-up paddling in a beautiful setting with its shallow waters. These and many other refreshing activities are - just like the water in Malente - often just a few minutes away.
