Petrinje - Socerb Castle

Access to starting point:
A) From highway Ljubljana - Koper we go to the exit Kozina, and then we continue driving on the old road towards Koper. When we get to Petrinje (smaller settlement on the right side of the main road, and on the left side of the road there is church of St. Boštjan), we turn from the main road and then we look for appropriate space for parking (in the settlement there aren't any parking spots).
B) From highway Koper - Ljubljana we go to the exit Kastelec, and then we continue right in the direction of Ljubljana, Kozina and Podgorje. Next follow two more crossroads, where we stick to direction for Kozina, and when we reach old road Koper - Ljubljana we drive there to the top of hill Črnokalski klanec, and then the road flattens and a little further it brings us to a smaller settlement Petrinje, which is situated on the left side of the main road (and on the right side of the road there is church of St. Boštjan). Here we turn from the main road (we can go left or right) and then we look for appropriate parking spot. At the starting point, there aren't any parking spots.

Path description:
When we step in the village we continue left, we walk to the power line pole, where the road ends. We continue straight, so that we few minutes walk by the road towards Koper, after that from the path which led us through a meadow we turn right into a lane of a low forest. Forest is quickly replaced by a lane of bushes, in the middle of which leads easy to follow, but often a little overgrown footpath. After few minutes, we reach an asphalt road which we follow to the right, and we walk there to a crossroad, from which we can nicely see nearby highway, which right here gets out of tunnel Kastelec.
At the mentioned crossroad, we go left, and after few 10 strides right on a marked footpath. The path ahead again leads through overgrown meadows and lane of a low forest and then it brings us on a narrower macadam road which we follow to the left. We walk on the road without large changes in altitude, or at first we are slightly ascending, but soon from the left joins the path from Črni Kal and Kastelec (also described path from starting points Varda and Žlebinje).
We continue straight in the direction of Socerb, on further wider macadam road which leads us on karst landscapes. Few minutes ahead we reach an asphalt road which we quickly leave because blazes lead slightly right, on the path which past the cave Sveta jama (entrance into a cave is locked) in few minutes leads back on an asphalt road. When we again reach the road, we walk there all the way to the castle Socerb, from which a nice view opens up.
