Korbu Waterfall, Waterfall in Altai Republic, Russia

Korbu Waterfall is a waterfall on the Bolshaya Korbu River in the Turochaksky District of the Altai Republic, Russia. It lies at the foot of the Korbu ridge, about 100 metres from the shore of Lake Teletskoye, where the river drops through a narrow valley along a tectonic fault. The cascade includes several falls, and a viewing platform rebuilt in 2020 stands 25 metres from the water.

The waterfall was designated a natural monument in 1996 and later became part of the Altai State Natural Biosphere Reserve. This status placed the surrounding land under formal protection, limiting human activity in the area.

The name Korbu comes from the Altai word "korbo" (Khakas "khorbo"), meaning shrubs or young tree shoots growing from a root. The waterfall and its right bank lie within the Altai State Natural Biosphere Reserve, where guided boat excursions from Artybash bring visitors to the site.

The waterfall can only be reached by boat from Artybash village on the northern tip of Lake Teletskoye, since no road leads directly to the site. Sturdy footwear is a good idea, as the wooden walkways can become slippery when wet.

In winter the waterfall freezes into a tall ice wall that local climbers use for practice. In summer the spray keeps the surrounding rocks constantly damp, creating conditions where mosses and ferns stay green even during dry spells.
