Kummakivi

Kummakivi is a large balancing boulder resting on a curved bedrock surface with only a tiny contact point. The stone measures approximately 7 meters in length and appears to balance precariously on the rock beneath it.

This massive boulder was transported and deposited by glacial forces during the last ice age, approximately 11,000 to 12,000 years ago. The movement of ice sheets left behind this unusual formation in southeastern Finland where it remains today.

The name Kummakivi means strange stone in Finnish, reflecting how locals have perceived and made sense of this boulder across generations.

The boulder sits in a forest area in western Ruokolahti municipality and is relatively easy to access for visitors. Sturdy footwear is recommended as the ground is uneven and the surroundings are covered with trees and forest vegetation.

Despite its enormous size and minimal contact point with the base, this boulder remains in perfect balance and cannot be moved by any effort. Visitors often attempt to push it, but it resists all attempts and holds its position firmly.
