Grijalica depression point is a natural phenomenon. It is fenced off area marked with information such as the name, altitude (892m) and the depth (28m). This depression point is located in close proximity of Delnice town, on the way to Mali & Veliki Petehovac passing Pavlakova Suta. Warm water vapour emerges from it hence it was named Grijalica (the heater). During the winter season, the snow is melted on this location due to the heat arising from Grijalica.
