Description of the cave
The main part of the cave is a 6-meter well accessed by a 2-meter, almost horizontal corridor that starts with a small entrance opening. A vertical clamp on the right leads into a 6-meter well that widens at the bottom. There is then a small room with rubble at the bottom.{{Citation|title=Jaskinie Polski, Państwowy Instytut Geologiczny – Państwowy Instytut Badawczy|url=http://jaskiniepolski.pgi.gov.pl/Details/Information/1451}}
There are no speleothems in the cave. Near the opening, mosses and lichens grow on the damp walls.
