The town of Pomorie is very popular with Bulgarians for the lye treatment. It is visited annually by people who experience chronic pain. Another famous place for lye and lye mud treatment is the lake of Atanasovo.
It is a hypersaline seaside lake, divided in two parts by the Burgas – Varna road. The north part is a natural reserve and the south part – a protected area. The lake is surrounded by smaller reservoirs and a canal system, which is overgrown with marsh vegetation and a freshwater canal. The lake area is around 17 sq. km. It is at 1.5 m under the sea level, which makes it extremely vulnerable. Its average depth is 30 cm.
