The 'heads' of the earth pyramids are made of hard andesite, which serves as an umbrella protecting the softer volcanic tuff soil underneath.
The mineralized water at the site is so acidic that it leaves behind distinct iron-rich reddish deposits, staining the surrounding soil.
The columns are constantly changing; as the protective stones fall, the pillars beneath erode rapidly, while new ones are formed nearby.
The local folklore traditionally attributed the formations to a petrified wedding party, but the site was only scientifically identified as a natural erosive phenomenon in the 20th century.
The concentration of minerals in the water is so high that it was historically investigated for potential medicinal properties, though it is not potable.
Devil's Town (Đavolja Varoš) is a unique natural monument located on the slopes of Mount Radan in southern Serbia, defined by 202 earth pyramids topped with stone caps. These formations were created by intense water erosion of nutrient-poor soil, which protected the ground directly beneath the stones from being washed away. The site features two distinct gullies, Djavolja Jaruga (Devil's Gully) and Paklena Jaruga (Hell's Gully), which contain the highest concentration of these formations. The area also hosts two natural springs with extremely acidic, mineral-rich water, known as Djavolja Voda (Devil's Water) and Crveno Vrelo (Red Well). The PH value of these springs is remarkably low, ranging between 1.5 and 3.5, and they are highly mineralized, preventing any aquatic life. In 2009, the site was a finalist in the New Seven Wonders of Nature campaign.
The elevated observation deck directly opposite the main cluster of towers.
Wear sturdy, closed-toe hiking shoes as the paths consist of uneven gravel and dirt.
Bring a windbreaker even in summer, as the mountain location can experience sudden temperature shifts.
Allocate extra time to walk to the viewpoint above the formations for a full panoramic perspective.
Do not attempt to climb the formations or touch the columns, as they are geologically unstable and prone to collapse.
The site is generally accessible from spring through late autumn, though access may be limited during heavy winter snow or extreme weather conditions.
Stay strictly on marked paths to prevent further erosion of the fragile soil columns and for personal safety.
