Saula blue spring is a freshwater spring in the village of Saula in Kose parish, in northern Estonia.
Saula Blue Springs consists of three main sources with a total flow rate of 20-30 liters per second.
The different colors of the springs (blue, white, black) are caused by the shade of the bottom soil and the reflection of light from the sand particles floating at the bottom of the spring.
According to folklore , The blue spring must have been the residence of the ruler of the mermaids, Blue springs are also believed to have a healing effect, which is why offerings have been brought there for millennia.
The springs are protected as a cultural heritage and natural monument.
