For years, the Keutschacher Seenradmarathon has been a permanent fixture in the cycling marathon calendar. Only a few minutes away from Lake Wörthersee, the Keutschacher See Valley offers vacation in its most natural form. 70% of the municipal area is a nature reserve, including valuable wetland moor areas. Bad Kleinkirchheim, the highest point of this stage, is a well-known winter sports and health resort in the middle of the Nockberge mountains (Tour 16). Lake Ossiach is considered the lake in Carinthia with the most fish. The monastery Ossiach is the oldest Benedictine monastery in Carinthia where since 1969 musical events of the "Carinthian Summer" take place in the summer months. Also in this stage you can see again the lake diversity of Carinthia, as well as the contrast "lake and mountain". Both can be perfectly combined on this tour.
