Astuvansalmi is one of the biggest rock painting sites in the Nordic countries. The paintings on a cliff next to a lake are thought to be 4500-5000 years old and they depict elk, human, hands, animal tracks, boats etc. The site can be reached by a 3 km walking path. You can arrive to the trail head from Ristiina by car. In Ristiina turn to Suurlahdentie, road 4323. Drive 19 km and find a small parking place with the Astuvansalmi sign. In winter the paintings can be viewed from the ice on the frozen lake. In summer boats trips are possible.
