Khanskoye Lake, Salt lake natural monument in Krasnodar Krai, Russia

Khanskoye Lake is a shallow salt lake in Krasnodar Krai, about 16 km long and 6–7 km wide, with a maximum depth of 1.8 m. A group of low islands made of sand and shell debris runs along its long axis; their shape and number shift with waves and water level. The lake lies behind a plowed field and a road, separated from the Sea of Azov by a narrow spit.

Lake Khanskoye began as an inlet of the Sea of Azov, connected to the Baisug Lagoon. Wave action built a spit of sand and shell that cut it off from the lagoon, leaving an oval basin about 16 km long. In 1988 the Krasnodar regional executive committee designated it a natural monument.

The name Khanskoye means "Khan's Lake"; the lake is also called Tatar Lake. Legend holds that a Crimean khan bathed in its healing waters, which gave the lake its name. Since the Yeysk resorts developed, local sanatoria have used the lake's sulphatic, carbonate and chloride mud against cardiovascular, nervous, musculoskeletal and skin conditions.

The lake is easiest to visit during warmer months when water levels are stable and shoreline paths are accessible. Wear sturdy footwear since terrain can be muddy in places and the ground is often uneven near the water's edge.

In dry years the lake dries up completely, exposing a salt bottom; in summer evaporation makes the water 12 times saltier than the Sea of Azov. Its islands, built of sand and shell, shift in shape and number with waves and water level, and hold some of the North Caucasus' largest colonies of Dalmatian pelicans and great cormorants.
