This study examines the physico-geographical and geoecological characteristics of Pasheno Lake, located within the Karkaraly National Natural Park in Central Kazakhstan. As one of the region’s key natural and recreational resources, the lake plays an important role in the sustainable development of local geotourism. The research aimed to evaluate th e ecological condition and tourism potential of the area through an integrated analysis of geomorphological, hydrological, climatic, soil, and hydrochemical factors. Fieldwork and laboratory studies were conducted in 2024 using standard sampling and Atomic Absorption Spectrometry to identify concentrations of major ions and trace metals (Pb, Cd, Cu, Zn, Mn, Fe, Cr, Ni, As), along with pH and salinity levels. The Müller and Hakanson indices were applied to assess ecological risk. The climatic analysis (1991–2024) showed moderate warming trends typical of a temperate continental climate, while soil testing revealed alkaline conditions (pH = 10.039) favorable for recreation. Results indicate that the water quality of Pasheno Lake meets national safety standards, confirming its suitability for tourism and recreation. Based on Reynard’s (2007) methodology, the lake demonstrates high scientific, aesthetic, and educational significance. The results provide a scientific basis for sustainable management and support the development of eco- and geotourism initiatives in Central Kazakhstan.
