This cave is located at 38º 28' 61" N 8º 59' 73" W down the mountains and dense vegetation (Vale do Solitário - covered forest), in towards Portinho da Arrábida. More specifically on the southern slope of the Arrábida mountain massif, at the base of a small cliff.

Discovered by chance, between 1856/1857, by a shepherd and friends, who were carrying out their daily routines, of grazing the cattle. From a speleological point of view, it is a deep cavity, resulting from the intense karst (bellow) activity of the area surrounding the cave

It consists of limestone rock from the Jurassic - J²p. Developing at an altitude of 210m/689ft, along a bedding joint. It presents a semi-vertical progression in the west-east direction, with a gap of -21m/69ft. Its area of about 174sqm/1873sqft.
