Paklenica Nacional park is situated on the southwestern hillside of South Velebit mountain and covers an area of 95 km2. The Park is part of the Dinaric karst, composed of karstified carbonate rocks on which the occurrence of caves is common. Over the years in total 112 caves have been explored within the Park. Within this research detailed GIS database of all explored caves were created, which was used to analyze their characteristics (type, morphological structure, length, depth, hydrological function, etc.). The study analyzes spatial distribution of entrances to caves in relation to relief features and existing hiking trails. The result of the analysis indicates the predominance of vertical (59%) over horizontal caves (41%). Likewise, 52% of objects have simple morphology, as well as small depth (79%) and length (74 %). Analysis of spatial distribution revealed that the objects are heterogeneously distributed within the Park, while 51% of explored caves are located in the ridge zone (above 1000 m). It was also found that most of the explored caves (63% of them) are in close proximity (up to 250 m) to the existing hiking trails. Analysis of spatial distribution of caves in relation to the lithostratigraphic properties has shown that as many as 75 % of the explored caves are located on carbonates with good permeability, while largest number of caves is in the immediate vicinity of the existing fault zones (73 %). Considering hypsometry, it can be seen that caves are present within all hypsometric classes, but that they are most frequent at altitudes between 500 and 750 m / nm (20%) and between 1 250 and 1 500 m (26%). There is a very high correlation between caves occurrences and slope, where most cave objects (62,5 %) are occurring on moderately steep slopes (12° - 32°). From the analysis, the representation of caves in relation to the slope orientation, shows that the largest number of caves occurs on the western and southern slopes. In regard to the analysis of terrain roughness, most caves (27,7 %) occur on highly rugged terrains. Analysis of correlation between caves and sinkholes shows that caves (primary pits) and sinkholes appear uniformly in individual units of the same morphometric relief features.
