The milk has colors from white to all shades of red and brown; giant stalactites, stalagmites, columns; The curtain has an admirable appearance with flag dripstones and dripstone pools. In addition to this magnificent view, the cave air, which varies within short distances, is thought to be positive for health. While the upper floors are hot (average 17 degrees) and dry (60-70% absolute humidity), the main cave is cooler (10-12 degrees) and humid (80-90%). This difference caused a distinct wind to occur between the upper floor and the main gallery.
