The mouth of the cave has large dimensions, 30 meters wide by about 15 high, forming a gallery about 45 meters long, occupied in part by blocks of rather large dimensions, appearing ascending in the first stretch to descend again in the final part. For a large part of the route, it preserves the dimensions of the entrance, reducing the height progressively. Below the highest part of the gallery originates a lower concavity about 15 meters long and about 10 wide and which is penetrated by a steep slope. Like other cavities in the Massif del Port, the walls are largely blackened. Cavity known since time immemorial. At the beginning of the 20th century, Neolithic remains were found and over time different archaeological activities of interest have been carried out. Mentioned in all the old speleological catalogues, it is, together with Cova Cambra, one of the most popular cavities in the Port. Lluís Porta i Massana, in his article, explains that during the wars of the 17th and 18th centuries, many of the residents of Mas de Barberans took refuge there, making each family a kind of living room with boxwood branches. He also explains that around 1828 a gang of 14 bandits, called "the Glebes", lived for quite some time in the lower chamber of the cave, even when shepherds and flocks slept in the big cave. It seems that they were the authors of twenty murders and robberies on the way out of Tortosa. They were able to arrest seven of them who died by hanging in Tortosa on January 29, 1829. Bayerri, in his Historia de Tortosa y su comarca (1934), comments that the name of the cave originates from the mineral crystallizations that are said to be there.

The Cova de la Dona can be found on the left (in the direction of the N-S march) before arriving at Pla de la MIna. It is one more of the many hollows on the route. It is signposted and the photo is almost mandatory.
