The massif is dome-shaped and has very steep ridges. Slavyanka has a pronounced karst character and thus features over 30 caves, attracting many speleologists. The climate has a considerable Mediterranean influence, with precipitation being at its highest in the autumn and winter and at its lowest in the summer, and the average temperatures being higher than in the rest of the country at this height. The average annual temperature in the lowest part of the mountain is almost 14°C and about 6 °C in the highest part.
