Kummakivi is an erratic boulder which was glacially transported to rest on top of a rôche moutonnée. The boulder is special since only around 0.5m2 of its surface area is in contact with the rock below it. The dimensions of the boulder itself are approx. 7m x 4m x 5m. There is a Saimaa Geopark sign at Kummakivenmäki parking area. Another sign is next to Kummakivi.
