The Łokietek Cave was known to the local population already in the Middle Ages. It was described in the 17th century. It is connected with the legend of Władysław Łokietek, who still as a prince of Kraków protected himself here from Wacław III who was looking for him. The future king was to live in the cave for about six weeks. Food was brought to him by a shaft in the vault, thanks to which the entrance was covered with cobwebs. This confused the pursuers looking for him. In memory of this story, at the entrance to the cave, there is a cobweb-shaped lattice.
Grotto Łokietek is the most famous cave in Ojców National Park. It consists of four rooms and a corridor. It has a poor infiltrative coat in the form of small stalactites and a stalactite column. The bottom of the cave is covered with rubble, and the roots of the vault hang in the chambers closest to the surface
The cave has an illuminated 270 m long tourist route. It is open to the public with a guide on duty at the entrance, which tells about its history and geology.
