In our research we explored the relation of green infrastructure and sustainable tourism development. We hypothesized that the concept of green infrastructure (GI) could be a catalyst for the development of different types of tourism products such as ecotourism and active tourism. Our objective were to analyse the green infrastructure, tourism attractions, and tourism infrastructure; to define the relation between green infrastructure and tourism; to explore the common development possibilities. In the frames of our project we analysed three pilot areas of different tourist characters. We defined those GI elements which have the most significant development potential for tourism products (eg. hiking trails, open spaces, green spaces of public institutions, lakesides, river banks). Based on the comparison analysis of attraction types and GI assets we defined those elements which can be the base of complex development. These can be public parks, alleys which can increase the value of tourism attractions such as castles, museums or programs. Our results highlighted a specific group of GI elements, the linear GI elements. So the development of linear GI elements is important from touristic, aesthetic and ecologic point of view as well
