Orekhovsky, Natural cascade in Sochi National Park, Russia

Orekhovsky is a waterfall in Sochi National Park, where the Bezumenka stream drops straight down into a rocky basin before meeting the Sochi River below. The falling water forms a narrow curtain against a vertical cliff face.

In the early 1900s, this waterfall was known locally as Melnichny, a name linked to milling activity that once took place in the valley. Over time, the connection to the nearby village gave it the name Orekhovsky instead.

The name Orekhovsky comes from Orekhovka, the settlement in the Khosta District of Sochi, and before the October Revolution the fall was called Melnichny, "the miller's fall". A grove of walnut trees stands nearby, along with rhododendron.

The lower 27.5-metre step is the one visitors reach; a metal staircase built in 1996 eases the final approach, and a café stands by the falls. The path runs through oak-chestnut forest with boxwood and Pontic rhododendron, so footing can be uneven. The site lies in the Khosta District, where the Bezumenka meets the Sochi River.

The waterfall became widely known through the amateur photographer I. G. Sutkovoy, who published a photograph of it in 1910. Before the 2014 Winter Olympics in Sochi, a Russian postage stamp was issued bearing its image.
