The region of Homolje in Eastern Serbia represents an area rich with numerous geological and geomorphological features, especially karst formations which are excellent representatives of this area’s geodiversity. However, the geotourism potential of these geosites still remains fully unrevealed. In this paper we analyzed the most representative ones based mainly on their aesthetic value as well as their geotourism potential. The aim of this paper is to emphasize the geotourism potential of Homolje and to determine its strengths, weaknesses, opportunities and threats as well as interactions between them when it comes to tourism development. The results of the SWOT and TOWS analysis indicate that Homolje as a tourist destination possesses immense geotourism potential but is still in the exploration phase according to the Butler tourist cycle of destination evolution. Research results also identify four different strategies which can be applied as solutions for current problems and for further tourism development.

Karst areas, as areas with attractive geological and geomorphological features are an important and integral part of geoheritage. They possess huge tourism potential and can be used for the development of geotourism. The Pek River basin is a highly dominant karst terrain with numerous geological and geomorphological features, especially caves. However, their geotourism potential still remains fully unrevealed. In this paper, we analyzed several geosites that represent significant karst geoheritage formations and as such they can be the backbone of future geotourism development in this area. The aim of this paper is to emphasize the geotourism potential of the Pek River lower basin and to determine the current state and geotourism potential of these geosites by applying the modified geosite assessment model (M-GAM).

Establishing sustainable and responsible speleotourism development is a major challenge and involves complex activities. Adequate theoretical starting point is the application of geoethical values related to the conservation and protection of the caves to be used for touristic purposes. Positive and negative cases of human behaviors towards speleological geoheritage are discussed, in order to highlight what should be done in cave management to avoid malpractices and on what elements could be founded adequate strategies aimed at promoting sustainable speleotourism. This is important to tourism management organizations involved in the promotion of caves and in creating economic opportunities for local populations, while respecting cave ecosystems. Modern cave management must be focused on the protection of the cave ecosystems, finding ways to achieve at the same time an economic development of local communities. But this approach needs the adoption of a geoethical framework of values to be shared by all stakeholders involved so that successful cooperation can be achieved despite differences in interests and expectations. The aim of this paper is to raise the awareness about the need to apply the values of geoethics to speleotourism, stimulating new fields of discussion within the scientific and technical communities involved in studies and activities related to geotourism and geoheritage. The possibilities of developing new ways to manage caves, in order to promote a sustainable socio-economic development of local communities, have to be balanced with the protection of natural environments as much as possible. The proposed theoretical frameworks have the goal to increase the discussion on the best ways of connecting speleotourism to sustainable and responsible cave management, presenting two case studies, and pointing out potential solutions.
