Lake Viljandi is in a primeval valley, which is 11 m deep, 450 m wide and 4600 metres long. The lake is well-known in Estonia thanks to the song about the boatman of VIljandi, who daydreams about the beautiful blue eyes of a girl he once saw when he was young. The trail that goes around the lake will take hikers to the observation platform on the other shore where you will see a charming and unique silhouette of the town.
