The Vintgar Gorge or Bled Gorge is a 1.6-kilometer gorge in northwestern Slovenia in the municipalities of Gorje and Bled, four kilometers northwest of Bled. Carved by the Radovna River, it is the continuation of the Radovna Valley.
The sheer canyon walls are 50 to 100 meters 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, the largest river waterfall in Slovenia.
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 hills Boršt (931 m) and Hom (844 m), towards the Upper Sava Valley.
This amazing gorge has a wooden walking trail that runs along the green river, leading to the beautiful 26-meter-high Sum waterfall. The end of the canyon is one of the most scenic and offers a panoramic view of the Bled region.
The gorge of Vintgar is well-known for its exceptional value which makes it a geomorphological and hydrological natural attraction of national importance. Its water is so pristine you can see the riverbed at almost every point. Also, its proximity with the popular Lake Bled helped Vintgar gaining the popularity it deserves.
Along the river’s edge, prior visitors have built lots of cairns. During a misty morning, like the one we had, these can be very interesting to photograph.
