Weaver's Cave, Natural cave in Rakov Škocjan Valley, Slovenia
Weaver's Cave extends roughly 2,885 meters underground with two separate entrances leading to passages that connect with the larger Planina Cave system. The formation creates an interconnected underground network with multiple levels and chambers.
Johann Weikhard von Valvasor first documented the cave in 1687 in the Philosophical Transactions of the Royal Society. This early scientific record made it one of the first cave systems in the region to gain wider recognition.
A prominent stalagmite formation inside resembles a weaver, inspiring a local legend about a craftsman who turned to stone for working on Sunday.
The lower entrance offers the main access point, and visitors should bring appropriate footwear due to constantly wet and slippery conditions inside. Warm clothing is advisable since the temperature remains cool year-round.
The Rak Creek flows through the cave system, creating a natural hydrological connection between Cerknica Polje and Planina Polje. This underground water network links two karst basins in a surprising way.
