From Vukov Konak follow the road to Vučja Luka, before the school turn right and follow the markation into the forest. There are several routes through the forest, you can follow the markation or this GPS track. It will both lead you to the foot of Crepoljsko. From there on it's an unpaved road that passes some small villages and will in the end bring to the road that goes back to Vučja Luka. Yes, it's a road, but there's hardly any traffic. Especially during the winter a very nice walk!
