The federal state of Austria Carinthia has long been a thriving tourist destination, since the advent of mass tourism in the 1950s it had seen double-digit annual growth rates in overnight stays. The prerequisites for this brilliant boom are given in Carinthia greatly. With its numerous lakes, the favorable climatic conditions and the diverse mountain landscapes, the southernmost federal state counts as one of the most popular tourist destinations and attractions of Austria. However, Carinthia struggled throughout its tourist development with strong structural weaknesses. Although there was a peak in tourism in 1979/80, the number of overnight stays decreased rapidly. Aside from an upturn in 1991/1992, due to different circumstances such as the opening of the East, especially the summer nights gradually decreased. The development of tourism has since faced problems. This thesis examines the causes and problems which were responsible for the decline. Hence, the situation referring to tourist accommodation, seasonal problems, strong concentration trends and the decrease in length of stay will be investigated. However, this thesis does not only aim at demonstrating causes of the decline in tourism, but also measuring strategies that have been set by different stakeholders in order to make Carinthia again popular with tourists.
