Access to starting point:
From Železniki we drive towards Tolmin or vice versa, we follow the road to the settlement Petrovo Brdo, where on the parking lot by the mountain hut Petrovo Brdo we also park. The mountain hut is located right next to the intersection, where the road to Soriška planina branches off.
Path description:
By the mountain hut, we notice signs for Črna prst, which direct us onto a very steep path. After a short steep ascent, we step onto a wide cart track, which we follow to the right, and it quickly brings us to a torrent stream. The marked cart track soon turns slightly to the left and then ascends relatively steeply through the forest. After approximately half an hour of walking, we come to mountain signposts, where a crossing is marked.
We continue in the direction of Črna prst (left Kup and Podbrdo) and continue the ascent along the ascending cart track, which higher turns to the right and becomes completely flat. After a few minutes of further walking, we leave the cart track and continue the ascent along the marked footpath. After a short ascent, the path levels out somewhat and brings us to an old but excellently preserved mule track. We continue the ascent along the aforementioned mule track, which through the forest and some gullies brings us to a crossing near Lovčev bivak Pri Koucah. Here we continue straight ahead (right Lajnar and Slatnik) and after some 10 steps of further walking we arrive at the aforementioned bivouac (Lovčev bivak is just the name of the hut and bivouacking is not possible inside it).
From Lovčev bivak we continue along the marked path in the direction of Črna prst. The path ahead crosses a strip of forest, then gradually transitions to increasingly panoramic slopes from which a view opens up onto the peaks and slopes surrounding Baška grapa. Higher up, the path turns slightly to the left and begins to descend gently. The path then bypasses an old barrack and brings us just some 10 m further to the hunting hut on Vrh Bače.
From the hunting hut we continue straight ahead (sharply right to Petrovo Brdo) and ascend to the pass Vrh Bače, where a crossing is marked. Here we continue left in the direction of Črna prst (slightly right along the road to Soriška planina, right uphill to Šavnik and Možic) and begin to ascend transversely through the forest. When the path has ascended almost below the summit of Šanc itself, it begins to descend toward a smaller saddle. The path first leads past the GRS hut, then we reach the aforementioned saddle. The path ahead first begins to ascend moderately, then gradually brings us to the ridge of Kobla, where it becomes even steeper. There follow a few minutes of steep ascent along the path that runs along the edge of the occasionally exposed ridge. Higher up, the path flattens, turns slightly to the right, and brings us to the less pronounced summit of Kobla.
Petrovo Brdo - Lovčev bivak Pri Koucah 1:00, Lovčev bivak Pri Koucah - Vrh Bače 30 minutes, Vrh Bače - Kobla 45 minutes.
