The forest made famous by the poem The Forest of Anykščiai, written by Antanas Baranauskas, is visited by everyone visiting Anykščiai. The forest begins at the southern outskirts of Anykščiai city and continues in a not very wide (about 1 km) strip on both sides of Šventoji River for almost 9 km towards Kurkliai town. The relief of the forest is very intricate with hills, pockets and slopes of Pašventupiai, carved with deep ditches. These ditches are the riverbeds of a number of springs – Marčiupys, Piktupis, Išplėstravis, Vingerštynė, Pakalnytė, Paramavietė, Gaugarys, Pašaltupys, Limenė and Šlavė. Šlavė sometimes penetrates deeply into the ground (sometimes even reaching 25 metre deep) between high shores and exposures. There are no other exposures in Lithuania, which would reveal traces of as much as three eras, which have witnessed the times of armoured prehistoric fish, continental regime and tropical climate.
