<p>Czechia, due to its location in Central Europe and long geomorphological development, has seen the development of a varied relief, and therefore the creation of different types of geomorphological landscapes. Recently, considerable attention has been paid to the research and evaluation of geomorphological landscapes. The concept of geodiversity and geomorphosites is mainly used for evaluation. So far, less attention has been paid to the Czech-Austrian border area, where the valuable relief of the Novohradské Mountains with a number of important geomorphosites is located. The main goal of this contribution is therefore the presentation of selected rare geomorphosites in the southern part of the Novohradské Mountains (Mt. Kamenec, Mt. Myslivna and Mt. Jelení) and their evaluation using the concept of geomorphosites. The basic methodological step was the detailed geomorphological mapping and geomorphological inventory of the area of interest, followed by the identification and selection of the studied localities—geomorphosites. The selected localities were then evaluated according to the existing methodology for evaluating geomorphosites, which is used in the Czech Republic with regard to a possible mutual comparison of the evaluated geomorphosites. The evaluated geomorphosites were compared with the previously evaluated sites in the northeastern part of the area of interest in the past research. We can state that all sites have a high scientific value with respect to their conservation value, the occurrence of specific forms of weathering on the granites, and palaeogeographic importance, with only the Jelení Mt. having lower total values due to the remoteness and poor accessibility of the locality. The acquired knowledge can be used for geoeducational and geotouristic activities in the study area. Another possibility for using this local geoheritage is the option of guided walks from local geotourism organizations.</p>
