Tolmin Gorges, the most visited attraction in the region of Tolmin, are the lowest entrance into the Troglav National Park. Confluence of two Alpine rivers, Tolminka and Zadlaščica, into a gorge is a unique phenomenon in Slovenia. The chute on the Tolminka River is the lowest point (180m) in Triglav National Park and the longest chute in Slovenia (about 200m). It is also among the deepest (60m under the Devil's bridge).
