The river Ai (Southern Ural, Russia) flows between high, forest covered, abrupt Ural mountains, and sometimes -vertical walls. Its banks are decorated with whimsical calcareous rocks as towers, fortifications, and columns. On the slopes of the mountains there are ideal viewing areas from which the panoramic landscapes of the valley of the Ai River, rocks and cliffs are opened up before us. The river’s current is swift and frequently there are stony fords, underwater and surface boulders, and numerous cascades.
One of the most beautiful places on the river Ai (Southern Ural, Russia) is the stone-wall “Big Pritesy”, with a height of up to 80 metres and extending more than a kilometre.
