Khyzhi, Protected lake and natural monument in Krasnodar Krai, Russia

Lake Khyzhi is a protected water body and natural monument in Krasnodar Krai, located in an area where multiple water streams converge into its waters. The lake and its surroundings of wetlands and neighboring fields form an interconnected water system.

The lake reached its present size in the 1880s, when a major landslide blocked a tributary in the upper reaches of the Tkhashomchuk stream, flooding the lower banks of a small existing pond. The Serbian Wikipedia article instead dates the damming works to the mid-1980s. It holds the status of a hydrological natural monument of Krasnodar Krai.

The Adyghe name Khyzhi means "little sea", and the lake is held sacred by the Adyghe, particularly the Shapsugs. Visitors can see dried tree trunks rising from the water, flooded when the lake expanded after a landslide.

The lake lies 2 km west of the aul of Maly Pseushkho, in the Tuapse forestry, on the eastern slope of Mount Tkhikhuray. Wooden bridges built for catching fish and crayfish stand by the shore, and a table with benches is set up for visitors. The water stays unfrozen almost all winter, with thin ice along the edge for a few weeks in January.

Dead tree trunks rise from the water, drowned when a landslide enlarged the lake in the 1880s. The Adyghe name Khyzhi means "little sea", and local Adyghe, notably the Shapsugs, regard the lake as sacred. Despite its 0.01 km², it holds crayfish and carp.
