Three little lakes can be found on the left bank of the Pirita River with many erupting “eyes” of streams, each with its own colour (bluish-green, white, dark). This puts together various colour combinations. These are often known as the most beautiful streams in Estonia. Some pump out as much as 20-30 litres of water per hour. It is said that the waters are good medical resources, particularly for the eyes. There are improvements in the area of tourists.
