Access to starting point:
The starting point of the path is across the road at the bus stop in Pliskovica (it starts on a concrete road). We can get to Pliskovica from the direction of Sežane through Dutovlje, or from the Vipava Valley through Branik and Komen.
Path description:
We start the path at the bus stop in Pliskovica. The path starts into the valley on concrete (approx. 100 m) and when we get to the valley a pond awaits us on the left. Exactly there is the crossroad which splits left or right. Both paths lead to Volnik.
We choose left and continue on the macadam road slightly uphill. The path is mostly flat with gentle depressions and leads all the time through the forest. Along the path we will also encounter the hunting observatory on the left.
When we get to the crossroad (triangular in shape), we can see signs with the names of trees. There we continue right. When we come to the next crossroad, we get to the road which comes if at the beginning at the pond we would turn right. There we go straight (slightly left) uphill on the footpath.
Soon after we step on the footpath we see the first sign for Volnik (wooden arrow). The path ascends all the time to the top through the forest and is well marked at every crossroad. After approximately half an hour of walking we come to a road (grassy) and there we can turn 100 m left, where under a nice branched tree there is a bench for rest. We return 100 m back and continue up the footpath for another 5-10 minutes and come to the summit.
On the top there is a mini panoramic platform with descriptions of birds, hills,...
The view is pleasant in all directions from the Gulf of Trieste, over the karst, to the Julian Alps.
I recommend poles and appropriate footwear.
