Pokljuška Gorge is a nearly 2-kilometer-long gorge at the foot of the Alpine plateau of Pokljuka. In some places, it narrows to just a few meters, with its walls rising up to 50 meters high. In 1930 locals built a passage with wooden bridges in the narrowest impassable section. The galleries are named after Prince Andrej – Andrej's Galleries.
The creator of the gorge was a glacier that eroded the rock and drained the water. Later, the water retreated to deeper layers, creating the largest dry fossil gorge in Slovenia. It is filled with various karst formations, including natural bridges, overhanging cliffs, and caves. The most famous transitional cave passage is the so-called Pokljuška luknja (Pokljuka hole), through which an old path leads to the Pokljuške rovte and further on to Pokljuka.
