The Astuvansalmi rock paintings are among Finland's most remarkable prehistoric sites, set on a cliff face above Lake Yovesi. Figures of people, boats, animals, and handprints survive in a landscape of water, pine forest, and stone, which is exactly the setting that gives them their force.
Reaching the paintings takes some effort, either by trail or by boat, and that is part of the reward. They are not museum objects removed from context; they remain in the lakeside world where they were made. Wear sensible shoes and check access details before leaving Mikkeli.
