Karhunpesäkivi (Bear's nest rock) is a large boulder rock that is hollow inside. It is located near the Ivalo-Inari road, about 25 km north of Ivalo. Karhunpesäkivi is the largest tafone in Finland, which is a type of rock formation that is created by the erosion of weaker material around stronger material. The cavity inside the rock is about 4 meters long, 2 meters wide, and 2-3 meters high. You can enter the cave through an opening at the base of the rock. There is a legend that a man who got lost in a snowstorm took shelter in the cave and found a hibernating bear inside. Luckily, the bear did not wake up and the man escaped when the storm was over.

At the parkin lot you can also find a cafe and a souvenir shop, and from there you can walk up the long stairs to the boulder.
