The rivers of Estonia

● We have over 7000 rivers in Estonia, but only 10 of them are over 100 km long

● The Vigala River is the longest river in Rapla County. It is 95 km long

● It begins in Keava bog, Rapla county and it takes its waters into the Kasari river, and together with it into Matsalu bay in the Baltic Sea.
