Boka Waterfall, Near The Soca River. Slovenia, Europe Royalty-Free Stock Photography

The Boka waterfall is supplied by a karst spring under an almost vertical limestone wall. Because of its karst nature, the spring has a relatively large discharge due to its underground drainage in the mountains of Kanin. The stream (also called Boka) flows for about 30 meters over a rocky shelf before falling over the rocks as a spectacular waterfall. This happens in two not so clearly separated stages, of which the upper one has a height of 106 meters and the lower one 33 meters. The width of the two stages is around 18 meters. Below the waterfall, Boka Creek flows over a steep valley with stony bottom and empties into the Soca River after less than 1 kilometer , which makes it one of the shortest streams in Slovenia.
