Lake Pikrolimni (Greek: Πικρολίμνη 'bitter lake') is an endorheic, alkaline salt lake in Kilkis prefecture, Greece.[1][2] It is located on the border of the Kilkis and Thessaloniki regional units, about 40 km northwest of Thessaloniki.[2][3] The lake is hypersaline, has rather shallow waters (0.5–0.7 m) and a shoreline of about 8.5 km.[3][4] The water surface area shows significant seasonal variation (3.2–4.5 km2) due to evaporation in the summer months, with an average value of 3.7 km2.[1][4]

Pikrolimni is the only salt lake in Greece and constitutes a biotope with rare halophytic vegetation surrounded by common reeds, which is home to various common and endangered bird species.[3][4][5] The habitat has been listed since 1996 as a Natura 2000 site of community interest and special protection area, while also protected by the Ramsar convention.[5]

The lake was known in ancient times as Chalastra (Ancient Greek: Χαλάστρα), a famous source of natron and trona for Graeco-Roman glassmaking.[1][6] In modern times it has been a site of pelo- and balneotherapy, with a spa specialising in such treatments using the lake's briny water and characteristic black mud.[2][7]
