research refers to the study of natural cavities in the geological-geomorphological context in the State of Paraíba. This work addressed nine natural cavities (the most representative) distributed in four municipalities of the state that developed in differentiated lithologies, such as: sandstone, limestone and granite. These cavities are distributed in the respective municipalities: two in the municipality of João Pessoa (Caverna da Onça and Caverna do Marés); two in the municipality of Santa Rita (Caverna do Índio and Gruta do Lobo guará); one of municipality of Alhandra (Gruta do Wilson) and four in the municipality of Araruna More precisely in the Parque Estadual da Pedra da Boca - PEPB (Pedra da Boca, Pedra da Caveira, Pedra da Santa and Furna do Caçador). These nine natural cavities constitute the most representative morphological expressions of the genus existing in the state of Paraíba. The main objective of this research is to study the different types of natural cavities on the Coastal and Eastern Agreste paraibano. The methodology employed in this work was envolved in bibliographical surveys regarding the natural cavities in the regional and local context of the researched areas. Several field researches were carried out with the objective of making an external and internal characterization of the cavities, giving data tabulation and thematic mapping of the interior of the cavities using Survex software. It was verified through the prospecting and mapping that the cavities mentioned in this research are in full transformation stage, caused by the dissolution, mechanical action of the water (piping) and the blocking of blocks in steep slopes. It can be verified for the first time, a study of natural cavity of carbonate lithology in the State of Paraíba, called the Gruta do Wilson. During the research it is noticed that all the cavities have a cultural value for the region where it is inserted, where some of them attract a significant number of tourists with the purpose of practicing leisure and adventure sports.
