Path description:
In Grčarevec we go downwards towards karst field. Half an hour we walk by the field with Unica, and then at the crossing we decide to follow the sign for Laze via Vranja jama 1h 10 min. The path goes upwards on a macadam, and after five minutes on the tree there are two signposts. One is pointing straight, the second right, and both are without inscriptions. We turn right on a cart track. Five minutes we walk through the forest and on the left we find a rock with arrows. One arrow is pointing straight, the second is pointing on a footpath uphill. We go straight, and after few steps, on the ground there is again an arrow by the blaze. Cart track changes into a footpath which soon turns to the right. Terrain becomes difficult and it leans downwards, and there is sinkhole Pod Stenami. We are accompanied by triangular blazes, and these are a sign that we are approaching a cave. We get to a crossing of two footpaths, both are without signposts. We decide for the right footpath, and the left goes past the rocky barrow towards the cave Skedena jama.

After two minutes we get to signposts with the caption Laze. We follow it and among rocks we ten minutes walk on a footpath upwards. On this part in wet there is a danger of slipping, on the right edge of the footpath runs on the wall of the sinkhole Pod stenami. Trees grow even in the sinkhole (this doesn't mean, that the mountain wall isn't almost vertical). We walk on a narrow path between the sinkhole Pod stenami and the cave. The trees by the path won't help much (before we grab them, check them). A view opens up on a field, and we are already before the steep ascent. After fifteen minutes of walking among rocks, the rocks will this disappear, and the footpath flattens. Five more minutes and from the cave on the right we will notice treetops. This is the cave Vranja jama and from here we already feel cold air. The path runs near the edge, where there are rocks (if we step to the edge, we can stumble. We also have to be careful not to slip on leaves). After a minute or two we get to a wooden fence, from here the footpath leads to the entrance of cave Vranja jama. The footpath (only partly marked) at first turns towards the wall, and then runs among trees. Temperature with every walked minute drops for two degrees. A descent to the point, at which we already see the entrance, will take five minutes. If you want to go inside the cave, during the rain (because of the water flow) it will be difficult to do.

From the cave Vranja jama to Laze we have only easy and short walk. Ten minutes on a macadam (via cave Najdena jama), to get to a crossroad with the asphalt road and there in fifteen minutes we get to the destination.
