We are now in a real wood of calcite formations. Stalactites which hang from the ceiling and stalagmites which grow upwards from the floor are there in all forms and sizes. The way passes by a beautiful, startling calcite pillar. In the following chamber grows the tower of Pisa. There is an important detail to be seen at the ceiling, the so called initial channel, the first way of the water, along which the whole cave was formed.
Steps lead down to the fourth chamber.
In front of us huge draperies of more than 10 meters of length hang from the ceiling. To the right we look into the Big Shaft, which leads down 60 meters in three steps and is filled with water at the bottom. There is the habitat of the famous Proteus, the biggest real troglodyte. As a special attraction we can have a close look at one specimen in a small pool left of the path. The animal is perfectly adjusted to live in eternal night.
