Windsborn Crater Lake (German: Windsborn-Kratersee)[1] is a water-filled volcanic crater in the Eifel mountains in Germany.

The Windsborn Crater Lake lies in the southwestern part of the Volcanic Eifel within the Volcanic Eifel Nature Park.

It is situated 1.2 kilometres east of the village church of Bettenfeld on the north-northwestern part of the Mosenberg hill (517 m above sea level (NHN)) just below the 470 m[2] contour.

The Landesstraße 16 runs past the two craters to the north-northwest and north along the valley of the Ellbach, a small tributary of the Little Kyll.

The L 16 links Bettenfeld and the town of Manderscheid, 2.8 kilometres east-northeast of the Windsborn Crater Lake and east of the Little Kyll.
