Geographically, it is located on the northern border of Cerničko Polje, at an elevation of 850 metres (2,790 ft) asl, just below and less than 100 meters to the west of Ključ village, Gacko municipality, Eastern Herzegovina region of Bosnia and Herzegovina. Geologically, object is located on the edge of Cerničko polje (karstic field) floor, at the thrust fault zone (overthrust), where eocene flysch and limestone make tectonic contact. In hydrogeological terms wellspring belongs to intermittent B-type (allogenic) resurgence karst spring. The wellspring cave entrance is very large with characteristic vertically elongated shape.

Vilina Pećina spring is one of the two sources of the short sinking river Ključka Rijeka.[1] There are also many other karst springs along the entire length of Cerničko Polje, mostly situated on its edges.
