You can trace the Osumi River back to the town of Çorovodë, where one of Albania’s wildest natural wonders lies hidden. 

Just south of the Tomorr National Park is this gorge, the deep walls of which have eroded to created an odd assortment of caves, passages and ledges.

 At places the cliff-faces are several hundred metres in height, and the shelter created by the gorge results in an microclimate that ensures year-round greenery. The best time to explore the gorge is in spring, when melt-water makes the entire 26 kilometres accessible by raft.
