Perkil's kettil, one of Sweden's largest giant's kettles, is nestled in the coniferous forest north of Tjällmo near Annsjön. The impressive kettle, which today is filled with water, gives a bottomless impression like the entrance to the earth's interior. The kettle was formed during the end of the ice age by a rotating rock that was drilled into the bedrock by the rushing water. The giant kettle is 12 meters deep and at its widest 4 meters. There is a bench by the car park.
Located just southeast of Annsjön. Drive north out of Tjällmo. Turn where it says Jättegryta 2
