The Saula Blue Springs are freshwater springs located in Saula Village, Kose Parish, Harju County in northern Estonia. There are three major springs that produce a flow of 20 to 30 litres per second. The springs are differentiated by their color: Blue Spring is blue-green; Black Spring is brownish black; and White Spring is blue-gray. The water from the springs flows into the Pirita River.
The springs are protected as a natural monument, as well as a cultural heritage site.
