Access to starting point:
From the highway Ljubljana - Jesenice, we take the exit Lesce, and then we continue driving towards Bled and Bohinjska Bistrica. From Bohinjska Bistrica we continue on the main road towards Lake Bohinj, and after the village Kamnje we need to pay attention, because on the right side, only a few meters before the beginning of the village Polje, we will park on the parking lot by the river Sava Bohinjka.
Path description:
From the parking lot, first we carefully cross the road, then for a short time we continue along the main road towards Polje. When we arrive in Polje, we continue left on a local road, along which we quickly walk to a smaller crossroad, by which we notice the first signposts for Orožnova koča mountain hut, Planina Osredki mountain pasture and Črna prst. We continue in the mentioned direction and further walk on a narrower asphalt road, which in a gentle ascent brings us to the next crossroad, where we continue on the lower right road (left Bohinjska Bistrica). The path ahead brings us to the beginning of the village Žlan and a little further to the center of the mentioned village. Above the village the asphalt ends and a macadam road brings us to a sort of turning point and a trough with water (we can also come here by car, which shortens the path by approximately 20 minutes).
From the trough we continue left, where first over a smaller bridge we cross the nearby stream, then we start to moderately ascend along the edge of an ample pasture. A little higher we cross the pasture fence, so we move to the inner side of the pasture. Further, we ascend through the ample pasture, and the path mostly leads through a very sparse forest. Higher we leave the pasture, and the path transitions into dense forest. Further, we cross an erosion-very-damaged cart track, then for a short time we ascend along a smaller torrent stream. The path ahead ascends to a poor forest road, along which for some time we continue the ascent. When we arrive at the crossroad where we join a wider macadam road (the road leading from Ravne towards Planina Storeča raven), we follow it to the left and even descend a little (when we reach the road we do not continue straight on the ascending cart track, on which the mountain signpost partly misleadingly points). After a short descent, a marked cart track branches off to the right.
We continue on the slightly overgrown cart track, which after a few minutes of further walking brings us to a marked junction.
We continue straight (left Črna prst past Orožnova koča and Planina za Liscem) on the cart track, which higher brings us into a smaller valley, through which we ascend to the next forest road. 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 steeply ascend. The path a little higher crosses an overgrown clearing (fern and raspberry bushes) and then returns to the forest, through which it continues all the way to Planina Osredki.
From the mountain pasture, where there are two smaller wooden huts (one is converted into a bivouac), we continue along the left side of the watering trough, on a poorly visible path that starts to moderately ascend among bushes and individual trees. The still poorly visible but well-marked path higher brings us to a somewhat larger meadow, along the edge of which we notice the next trough. 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 transversely. 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.
From the ridge, from where a beautiful view opens towards the south, we continue right in the direction towards Vogel (left Črna prst 10 minutes). The path ahead becomes more demanding as, with the help of steel cables, mostly without them, it crosses very steep grassy slopes that are dangerous for slipping. The path then levels somewhat and brings us to the Vrata saddle (1721m). The path then again withdraws from the ridge to the left and thereafter ascends transversely over the next steep slope. That the path is not entirely easy is indicated by a memorial plaque. The steepness of the slopes then gradually eases, and the path again approaches the main ridge. For the ascent to Četrt at this point we leave the marked path and continue sharply right, first along and then on the ridge. After a few minutes the ridge widens, and we follow it across the extensive summit slope to the top, where we notice an old boundary marker from 1920.
