The cave was discovered on January 3, 1961 by Gencho Kotsev, Georgi Zlatarev and Boris Evtimov. The same year it was also studied by a team of BAS – Dr. G. Markov, N. Djambazov, Vl. Popov and Al. Petrov. The materials from the drilling archaeological excavations are dated from the Early Iron Age and Thracian-Roman times. The cave was used as a temporary dwelling of the Thracian tribe Bessi about 2600 years ago. In 1968, scientists from the Geographical Institute of BAS and members of TD Kupena – Peshtera made detailed topographic and geomorphological studies. In the early 1980s, geophysical surveys were also conducted. It became officially open for tourist visits in 1968 by the City Council in Peshtera. The name was given by Al. Petrov due to the whiteness of the cave shapes and the limestone formation, resembling the female figure, naturally formed in the so-called Magic Hall.
The cave is situated at the foot of the rock wreath Lilova rock, on the left valley slope of the Novohmahlenska River, about 5 km southwest of the town of Peshtera. The entrance of the cave is small, located between high beech trees at 865 m above sea level. Snezhanka is declared a natural landmark with Order № 512 / 14.03.1961. The cave is one-storey, descending, with six halls, the largest of which is the Great Hall (48 x 36 x 12 m). Its main axis is 145 m long, with an area of 3150 m2. From the ceiling hang thousands of snow-white stalactites. The great hall is also interesting because of the Thracian artefacts. In the middle there are remains of an outbreak around which many bones of wild animals, a bronze needle and a ceramics were found.
Throughout the cave there is a wide variety of sinter forms and sinker lakes formed by infiltration-dripping waters. Iron stairs lead to the first hall called the Hall of the Udders (because the stalactites resemble udders). From there you pass into the Great Hall measuring 60 x 40 m and 12 m high. The stalagmites, which resemble a stone forest (mace, candlesticks), are characteristic.
This hall is connected to the Musical Hall with its distinctive ringing formations. Southwest of the Great Hall is another hall in which there stone blocks from the ceiling that have collapsed. The southernmost hall is named Valshebna. Here you can see many beautiful blue lakes. On the way out, a narrow pass leads to the Beard Hall, named after the dark-brown roots of ancient beech trees hanging from the ceiling.
