Access to starting point:
From the road Hrastnik - Rimske Toplice we drive to the center of the settlement Dol pri Hrastniku, where by the parish church of St. Jakob and the NOB monument the described path begins. We park at one of the parking lots in the center of the settlement, or we can also park at a slightly larger parking lot by the cemetery, which is less than five minutes from the start of the described path.
Path description:
From the starting point, we head north, following signs for Kal (a path south leads to Gore), and bypass the church on the right side. We initially walk on a sidewalk along the road Trg borcev NOB, and later along Partizanska cesta. At the company Spectra 9 d.o.o., the sidewalk ends, and shortly after, we reach the path Srečno. We generally do not follow the signs for this path, as our route and the path Srečno coincide only briefly.
A little further, at the memorial of Slovenia’s independence, we turn right onto a side road, then follow Knafelc blazes (the path Srečno veers slightly more to the right here), ascending past individual houses. After the last house, we transition to a steep cart track that leads into the forest. In the forest, we turn right from the cart track onto a footpath that ascends quite steeply, and higher up, slightly bypasses a nearby homestead to the right. Upon leaving the forest, we cross an asphalt road leading toward the settlement Krištandol (turning left downhill allows a return to the starting point), then diagonally ascend a grassy slope, from which a first view opens toward Kum, the highest peak of Posavsko hribovje. When we re-enter the forest, we gradually move onto steeper slopes, ascending diagonally, requiring extra caution, especially in wet conditions. The steepness of the slope soon eases, but the path remains quite steep. Higher up, we reach a road leading toward the cottage Planinski dom na Kalu, the ski slope Rajska dolina, and some hamlets (here, too, turning left downhill allows a return to the starting point or to Hrastnik).
The path continues along an asphalt road, mostly ascending moderately. At the second left turn, a marked path from the settlement Marno joins from the right, passing through Krištandol (with signs for Gore and Kopitnik).
A little further, the road flattens and leads to a junction at a small saddle, where an NOB monument is located.
Here we go right in the direction of signs for Ostri vrh, Baba, and Zavrate (left Hrastnik over Blate, straight Kal and Mrzlica).
The path ahead leads us on a macadam road that leads towards the nearby homestead; just below the homestead, we turn slightly left onto a cart track that leads us to the left of an abandoned farm, behind which we enter the forest. In the forest at the crossroads, we follow the blazes, and the path continues with some moderate ascents and short gentle descents.
As we approach Ostri vrh, an unmarked but quite well-trodden path from Krištandol joins from the right, but we follow the blazes and move onto quite steep and slippery slopes, through which we steeply ascend. This path, where extra caution is especially needed during the descent, we follow all the way to Ostri vrh, a few minutes away, where there is an inscription box.
