The naturally beautiful Small Wolf Ravine stream flows from Lasnamäe into Kadriorg at the eastern edge of the park, near the Song Festival Grounds. The stream has gouged out a 10-15 m deep gulch, which in turn has formed a 2.5 m high waterfall. In the spring, the Small Wolf Ravine used to be a real waterfall, rushing down the stone streambed; in the summer, the water almost dried up. In the 19th century, it was a popular outing spot for locals. The waterfall’s name was inspired by Carl Maria von Weber’s opera Der Freischütz. Many painters have captured the natural beauty of its scenery.
However, due to construction activities in Lasnamäe, the stream has lost its abundant flow and former charm.
