In the cross-border development programmes regarding ecotourism plays an outstanding role the system of regional national parks (Aggteleki and Slovensko Karst National Parks). It shall get a special role since the WTO designated the year 2002 as the year of ecotourism. The survey deals with a special territory of the Hungarian-Slovak borders, because the region has varying natural resources. The methods of our analysis were on the one hard fieldworks on the other hand questionnaires among local authorities. At first were searched the potentials (natural and cultural) of the area then were determined the possibilities of ecotourism. It may be felt from the later drafted brief outline that the basic preconditions of tourism are given for Aggtelek-Slovak Karst Mounten and the Tokaj-Eperjes Mountain.
