SummaryAccording to the subject Natural ressources of the nature park region Bad Kleinkirchheim and their touristic commercialization I have first dealt with the natural ressources for tourism in Bad Kleinkirchheim, such as the geographical location, the landscape, the climate, the hydrology, the geology and the connection between geology and thermal water. Since spa water is one of the fundaments for Bad Kleinkirchheims touristic developments, I have added a rather extensive chapter on thermal water from a medical point of view.The second part of my paper contains in the first section a shortdescription of the current situation, the development from a rural villageto an international tourist destination, and the various types of tourismin Bad Kleinkirchheim, with a focus on health and wellness tourism as one of the main fundaments.The second section of the second part of my paper throws some light on thetwo most important facilities in regard to infrastructure, the thermal bathsand the lifts and cableways, and furthermore the ÖEK 2007, a touristdevelopment concept, serving as a guideline. In this chapter also thecontroversial issue of second homes will be discussed. I am going to finishmy paper with a SWOT-analysis, marketing and PR measures, guidelines and aconclusion. This paper has involved much work and research, but it hasbeen rewarding and very interesting. Thus, I hope to meet the expectationsof my teacher Prof. Lazar.
