The area of Grabovača is characterized by landscape values that make it a recognizable hill area of this part of Lika. In the relatively small area of Cave Park Grabovača there are 9 speleological objects protected by the Nature Protection Law. Besides that, caves Samograd, Medina and Amidžina are individually protected (in 1964) by the Nature Protection Law in the category of geomorphological monuments of nature. The Park’s area is dominated by hills covered with low woods (coppice) of common beech and sessile oak. The highest peaks are Šutića vrh (787 m asl) and Grabovača (770 m asl).
Out of the animals that really or potentially inhabit the wider area by the Nature Protection Law there are 39 protected species. Many protected and endangered bat species need to be mentioned, and also the presence of two Croatian big beasts (wolf and brown bear). By ornithological research the presence of 60 bird species has been determined, out of which there are 55 nesting species. The nesting colony of Alpine Swifts (Tachymarptis Melba), one of the rare nesting colonies in non-Mediterranean Croatia needs to be noted.
The river Lika flows in the bordering areas of the Park – second largest subterranean river in Europe by its length (78km).
Out of the recorded habitats, there are four types that are endangered and protected on the European level (brome grass and fireweed meadow, sessile oak and hornbeam forest, forest and scrub of hop hornbeam with autumn moor grass, beech forest with large balm-leaved archangel). In the flora diversity, 16 plant species that are protected by the Nature Protection Law (Regulations for the proclamation of wild species protected and strictly protected) stand out. Three endangered and protected on the national level species are: Orchis purpurea Huds (Lady Orchid), Orchis tridentata Scop (Three-toothed Orchid) and Orchis morio L. (Green-winged Orchid).
