Lake Elton (Russian: Эльтон; Kazakh: Эльтон, romanized: Elton) is a salt lake in Volgograd Oblast, Russia, near the border with Kazakhstan. It has an area of 152 km² and is about 0.1 m deep (in spring 0.7 to 0.8 m). Its surface is 18 m below sea level.[1] The lake’s name originates from the Mongol language: “Altyn-Nor” (Golden Bottom). Long ago local nomads used the lake’s mineral-rich mud for skin and respiratory treatments.[2] For centuries, Lake Elton was a favorite location for Russian rulers and nobles. One can still see remnants of Empress Yekaterina II’s “bath” there.[2]

It is the largest mineral lake in Europe and one of the most mineralized in the world. The lake is filled with a saturated salt solution. Mineralization is 200–500 g/L. Salt, extracted from the lake since the early 18th century, is used for the production of magnesium chloride.[3] The water contains Dunaliella salina algae that give a reddish shade to the lake. At the bottom of the lake are salt deposits (mainly NaCl, KCl) and beneath them, a layer of mineral hydrogen sulfide mud.
A bus ride can be taken from Volgograd (6 hours mostly because of long stops in rural towns) and also by train from Saratov and Astrakhan (also 6 hours) can lead travelers to the area.
Salt was excavated from Elton beginning in the early eighteenth century.[4] Before 1865 the government was the excavator; from 1865–1882 the lake was heavily used by private businesses.
A spa resort has been located near the lake since 1910 and a sanatorium since 1945. Sulfide silt mud and brine from Elton are claimed to have anti-inflammatory, detoxifying, analgesic, relaxing and revitalizing properties.[5]
The Elton Ultra Trail is one of Russia's toughest races. There are two distances of 38 km and 160 km. It was first organised in 2014.
