Vintgar Gorge

The Vintgar Gorge or Blejski Vintgar, Bled Gorge is a 1.6 km gorge located near the settlement of Zgornje Gorje, four kilometers northwest of Bled, Slovenia. Carved by the river Radovna, the sheer canyon walls are 50 to 100 m high, with a total slope measuring about 250 m. The stream has created many erosive features such as pools and rapids, and terminates in the picturesque 13-m Šum Falls.

Before the last ice age, the Radovna River flowed eastward. After being dammed by the ice and detritus of the Bohinj glacier, the resulting lake cut a new path northeast through a soft layer of triassic limestone between the peaks Boršt (931 m) and Hom (844 m), towards the Upper Sava Valley.
