Quiet and the Wild gulch

Both the Quiet and the Wild gulch form in fact a rocky canyon, with the river Kamenice hurrying through its sheer or even vertical rock walls. The Kamenice empties into the river Labe (Elbe) in a place called Hřensko, yet before its water reach the Labe (Elbe), they fill the entire bottom of the gulch, and - on two patches - tourists must use the ferry.
