The aim of the paper is to introduce the possibilities of managing the development of new tourism activities associated with visits to national parks. Sustainable activities, especially in large-scale protected areas, which include national parks, are developing training examples for local residents and the provision of guide services themselves. Case studies present the unique wilderness guides project in the Sumava National Park. Emphasis is placed on the co-operation of public institution with local residents, which is one of the basic forms of participatory management of the territory. First, it's focused on the theoretical, general issues in terms of national parks, knowledge management and human resources management - especially in respect to current trends in employee savings in individual institutions. From the theoretical paradigms, Cohen's guide roles were analysed. The ttinava National Park was chosen as the case study, which is unique in terms of developing the concept of local guides training. This paper descnbes the development of this activity and the development of a two-stage division of the guides. Finally, the results are summarised with the emphasis placed on the indispensable role of each national park as a publicly established institution that is also economically among the major players in each region.
