Attraction: it is a small lake created by the carbon dioxide filled upward stream flowing to the surface from carbonate rocks of Upper Jurassic period. The lake "boils" loudly from carbon dioxide bubbles. The debit of the stream is 2.5 liters per 24 hours. The total surface area of the lake is 0.04 ha. The extraction of gas in not so windy weather causes carbon dioxide to accumulate in lower layers. Small animals suffocate when they get near the lake, which is why you may come across dead animals, such as: mice, lizards, frogs and some birds.
