Devil's Town (Đavolja Varoš) is a unique natural monument in Serbia, featuring over 200 eroded earth pyramids and two highly acidic mineral springs, a site often considered for UNESCO recognition. While accessible by car to the entrance, exploring the formations involves walking on well-maintained paths, generally suitable for most fitness levels, though not fully wheelchair-friendly due to varied terrain. Visitors can explore independently, but guided tours from nearby cities like Niš or Belgrade offer convenience and deeper insights. The best time to visit is from spring to autumn (April-October) as winter can bring snow, making access difficult and potentially closing some paths or facilities. An approximate entrance fee is around 3-4 EUR/USD, with guided tours costing more. A typical visit to explore the formations and springs lasts 1.5 to 3 hours; comfortable walking shoes are recommended, and the formations are particularly striking during sunrise or sunset, enriched by local legends.
