The Blue Lake, formed as a result of a sinkhole, has been known since ancient times. Springing up from its bottom is a powerful hydrosulfuric spring. There is no life in the lake, which explains its transparency. The beauty of the lake is truly memorizing – its clear depth (approximately 17 meters) beckons to be gazed into again and again. Luckiest of all are those who know how to dive. According to divers, if you take the plunge and look towards the surface, you can see, just as in a painting, the clouds floating by in the sky, the trees growing along the shore, and all of your awaiting friends.
