Big and Little Valley

Big and Little Valley are notable in the botanical terms. On their steep rocky slopes to a small area settled by representatives of different floristic regions: Ostrya carpinifolia (Illyrian region) Cyclamen purpurascens (Mediterranean), Euphrasia talarica (Pannonian). In addition, you can meet the Ice Age relic plants: Primula auricula bauhinii, Saxifraga incrustata, Viola biflora and other underground river path cavers managed to trace nearly 3 km. But for tourists see only half of it. Narrow path in the cave clings to the steep, sometimes overhanging cliffs winding canyon, dimly lit light bulbs, dropping the ghostly shadows of the bottom of the darkness came the only continuous rumble rivers. At the dizzying height of 70 m above the boiling flow along the narrow bridge you can jump to the other side of the dark abyss. More fantastic journey through the underworld hard to imagine. In the creation of an underground limestone gorge took part, of course, no one chemical dissolution play an important role as the usual mechanical erosion of water. Drop it within a very large cave -6.3 m per 100 m. As in the Postojna Cave - Yama, here the river ran deeper, predominantly in the glacial period. Incidentally, after heavy rains and during snow melt level of the river sometimes rises sharply: in 1826 he climbed the 70 meters! Big Valley turned into a deep lake.
