Erastvere is one of the oldest settlements near Põlva. There is an old manor park with the tallest lime-tree in Estonia, with the height of 35 m. A chapel of the noble German family von Ungern-Sternberg which is built on the foundation of the former Church of Mary and called after the last family member born in Estonia – Gerhard – is located in the middle of the park. The park also includes the fascinating Lake Erastvere which offers good opportunities to bathe, camp and spend a good time. The Ahja River starts from the north-eastern part of Lake Erastvere.
