Surrounding Karapınar, 94km southeast of Konya, are numerous crater lakes, the most famous being the lovely Meke Crater Lake with an island in the middle. When viewed from above, it is seen as a black spot surrounded by blue water. Because of this image, the lake is considered as the "Evil Eye Bead of the World".
On the north side of the road to Ereğli, 10km from Karapınar, lies Acı Crater Lake.
