When translated from the Tatar "uchan-su" means "flying water". The highest Crimean waterfall is on one of the slopes of Mount Ai-Petri and is born from the same name river Uchan-Su. A powerful stream rushes from a height of 98.5 meters. The waterfall consists of four cascades in height 90, 15, 7 and 8 m. The noise from the waterfall spreads all over the gorge.
In the spring, the waterfall Uchan-Su is filled with melt water, and at this time demonstrates all its power and full-flowing beauty. In the summer a couple of small jets remain from the waterfall, since all the water goes to the water supply of Yalta. In cold winters the waterfall Uchan-Su freezes becoming an ice cascade frozen in flight over the precipice. During the summer it is necessary to buy tickets for passage to the observation deck of the waterfall, and in other seasons, when the waterfall is full and cascades to the full extent of its power, admission is free.
