Path description:
Across from the inn Gostišče GTC 902 Črnivec, by the water filling point 902, we notice the mountain signposts, but we head onto the path in the direction of Veliki Rogatec, Lepenatka and the top of Kašna planina (Kranjska reber). It is best to start along the macadam road which branches off from the main road towards the north, from which we go left after a few steps onto the path which starts to ascend through swampy terrain. Initially the swampy path continues through the area where there was a strong windstorm years ago (13 July 2008), and today after artificial planting the slope is regrowing. Because the trees are still low, in summer the undergrowth and bushes grow strongly, so the path on this section is quite overgrown in summer. Along the quite overgrown path we walk to the place where we cross the road, then on the other side we continue along the cart track, which is also still quite overgrown. When we cross the road for the second time, we arrive at the upper part of the slope where the windstorm raged, so the path ahead is less overgrown. On this section the path also levels out somewhat and turns slightly to the right, where it first crosses a stream, then continues through mostly spruce forest. A little further we cross another road, then ascend diagonally through the forest; the path takes us past a smaller spring to the saddle Na križu, where an unmarked path from Kališa joins from the left.
We continue straight on the marked path, which ascends somewhat more steeply, then crosses a grazing fence and brings us out of the forest, where an unmarked path from the Volovljek pass joins almost imperceptibly from the left.
Here we continue straight and walk for a few minutes along an indistinct cart track with nice views, from which we soon go right onto the mountain path, along which we quickly ascend to a smaller watering place for animals. From the watering place a few minutes of moderate ascent follow, and the increasingly scenic path brings us to the top of Kranjska reber, where there is an inscription box.
After resting and enjoying the views, we continue along the path towards Lepenatka. The path ahead starts to descend moderately along the indistinct northeastern ridge of Kranjska reber, then past some watering places brings us to the hut on Kašna planina.
From the hut we continue the descent along the nearby road or along a marked shortcut, along which we arrive at the junction with the wider macadam road in 5 minutes. Here we first go right (left to Volovljek pass), then after a few steps left (straight we return along the macadam road to the starting point at the Črnivec pass), both times in the direction of Lepenatka. From the junction we walk along the road, which descends gently while crossing the eastern slopes of Kašni vrh. After a few minutes we reach the ridge, where the road ends at the turning area Leška gmajna; we continue straight along the marked footpath, which enters the forest, through which it first descends moderately, then more steeply. Lower we reach a forest road, which we follow straight ahead; then, when the road turns slightly right from the ridge, we continue straight onto the ascending cart track, beside which there are also blazes. The cart track first ascends steeply along the ridge, then from it an unmarked cart track branches off slightly to the left and downward, which after a short transverse descent joins the forest road, along which it is possible to continue to Bivak na Kalu; we however continue straight, first briefly along the cart track, then slightly right onto the marked footpath. The path immediately starts to ascend steeply, soon turning a bit more to the right, where it ascends diagonally across a steeper slope. Further on the path ascends steeply, occasionally leading us over some shorter exposed section, where greater caution is needed especially in wet conditions and snow. Higher up the slope gradually flattens, the path turns right and brings us to the ridge east of Kunšperski vrh (also Brezovec).
When we reach the ridge we continue right (left to Kunšperski vrh, 5 minutes of easier pathless terrain) along the marked path, which continues along the occasionally scenic ridge. Further we ascend gently to moderately along or slightly left of the ridge. Higher the path leads over a grazing fence, beyond which we step onto the summit grassy slopes of Lepenatka. A few minutes of moderate ascent follow along the path, from which beautiful views open up reaching from the nearby Veliki Rogatec across Raduha and Olševa to the highest peaks of the Kamniško Savinjske Alps, and we reach the grassy summit of Lepenatka.
From the summit of Lepenatka we continue a few dozen steps along the ridge, then at the marked junction left downward in the direction of the Kal saddle and Veliki Rogatec. Approximately 15 minutes of moderate descent follow first along a quite scenic grassy slope, then we arrive at the Kal saddle, where there is a marked junction.
From the junction we continue straight left and walk to the nearby bivouac.
