Access to starting point:
From the Ljubljana-Jesenice motorway, we take the Lesce exit and follow the road towards Bled and further towards Bohinjska Bistrica. From Bohinjska Bistrica, we continue left in the direction of Tolmin and Soriška planina. Soon we will notice signs for Črna prst to the right by the road, but we continue straight. Only a little later we come to an intersection, where a signpost directs us right towards the village of Ravne. We turn onto this road, which brings us to the end of the village, where the asphalt ends. Further on, we continue on the macadam road, which leads us past the former home of Dr. Janez Mencinger (today a private house). We then follow this road for approximately 4 km to the spot where a worse forest road joins from the right side (nearby is a hunting observatory, numerous cart tracks and a mountain signpost for Črna prst). We park on one of the several smaller parking areas by the road, but in such a way that we do not hinder forestry work (timber hauling).
Path description:
Due to forestry work and the consequent numerous tractor tracks, the beginning of the path is relatively hard to find. Between the hunting observatory and the mountain signpost for Črna prst there are three larger cart tracks that head left uphill from the road (direction of our arrival). We choose the "first", that is, the one closest to the hunting observatory (the mountain signpost for Črna prst directs us to the "last" cart track, but if we follow the direction of that signpost we will quickly go astray).
So if we have decided on the ascent along the "first" cart track, we will already notice the blazes after a few minutes of ascent (the path comes diagonally from the "last" cart track and is completely overgrown). We then follow the wide tractor tracks somewhat to the left, but only to the spot where the blazes direct us right onto a somewhat narrower cart track. Further on, orientation is much easier, as the labyrinth of cart tracks ends. From the occasionally somewhat steeper path, a marked path towards Orožnova koča soon branches off to the left.
We continue straight along the cart track, which higher up brings us into a smaller valley, up which we ascend to a forest road (to here we need approximately 30 minutes). When we step onto the road, we continue a few steps to the left, then the mountain signpost for Črna prst directs us right into the forest, where it starts to ascend steeply. The path somewhat higher crosses an overgrown clearing (ferns and raspberry bushes) and then returns to the forest, where it continues all the way to the mountain pasture Osredki.
From the mountain pasture, where there are two smaller wooden huts (one converted into a bivouac), we continue along the left side of the watering trough pond on a poorly visible path that starts to ascend moderately among bushes and individual trees. The still poorly visible but well-marked path then brings us higher to a somewhat larger meadow, at the edge of which we notice the next pond. The path then ascends ever more steeply and slowly turns to the left. At the top of the ascent, we step onto a smaller saddle, behind which the path turns right and ascends diagonally. A few more minutes of ascent follow on the slope overgrown with dwarf pines, and the path brings us to the main ridge of the Lower Bohinj Mountains.
We continue left (right Rodica) and follow the relatively gentle path running along the panoramic ridge to Črna prst, which we reach after 10 minutes of further walking.
