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.

Forest Park Japlenski peak (842 m above sea level) with size of 170 hectares, is located on the west side of Delnice. Nearby there is an enclosure for deers and you can bring a few carrots or apples and enjoy treating them with a tasty snack. Biking trails and walking paths continue from central park into the forest. 

On the north-east side of Japlenski peak, there is an old 70-meter ski jump hill landing at town stadium. Latest addition to winter activities is ice skating ring, also located at the central park.
