Forest parks were created on karst terrain, which is why, in addition to forest vegetation, some of them also feature extremely well-developed and rich karst phenomena. A typical example of this is the forest park Golubinjak, near Lokve.
The spacious green clearing surrounded by tall coniferous trees rising high above the white rocks, take the breath away of almost all those who visit Golubinjak. This small area includes most of the special natural features relevant for the forests of Gorski Kotar, developed in carbonate karst terrain.
