Crimea's largest salt lake, Moinaki Lake, is located on the western outskirts of Yevpatoria. It is 1.85 km long and 890 m wide. The bottom of the lake is rich in therapeutic mud that is used to treat musculoskeletal disorders, as well as skin, urological and other conditions. In summer, the lake's water takes on a reddish or greenish tint due to the algae growing in the lake.
