Kummakivi (“strange stone”) is a large balancing rock in Ruokolahti, near the border of Puumala, that has been protected since 1962. The 7-metre long boulder lies on a convex bedrock surface with a very small footprint – but so firmly that it cannot be rocked with human force. A pine tree originating from the 1980s grows on top of the boulder.
