Happy tourist woman traveling by off-road on stone road between steep cliffs. Enjoying exploring different places, cities, nature. This road has big rifts and sharp bends. This is one of the most difficult roads in the world. Karanlık Canyon (Turkish: Karanlık Kanyon), literally “Dark Canyon”, is a deep steep-sided gorge located between the İliç and Kemaliye districts of Erzincan Province, Turkey, formed by Karasu River on the Munzur Mountains.
