Another natural rarity in “Devil’s Town” are two springs of extraordinary properties. “Devil’s Water” (“Djavolja voda”), which is located in vicinity of these earthen figures, is a cold and extremely acid spring (pH 1.5) of high mineral concentration (15 g/l of water), springing out in “Devil’s Gully”.

In comparison to drinking water, it is 10 to 1000 times richer in minerals (aluminium, iron, potassium, copper, nickel, sulphur, and alaun). “Red Well” (“Crveno vrelo”) is another spring located downstream, in the alluvial plain, 400 m away from the first spring. Its water (pH 3.5) is less acid and has a lower general mineral concentration (4.372 mg/l of water).

Because of the flat terrain, its water overflows in a very thin layer and runs into a bed of the nearby yellow stream. Due to the oxidation of iron, which is contained in water in large amounts, an attractive red terrace in the form of a fan is created.

Such waters are very rarely found in the world. They are similar only to two waters in Italy (Levico and Roncello), and three in Russia (Zubinskije, Bljavinskije, Karabasskije).
