We took the train from Podbrdo to Hudajuzna and walked from there, maybe it cut the distance 2/3 but it was still quite a strenuous hike. You can also walk to Hudajuzna and go by train from there to Grahovo if you want an easier hike.
Mostly it was a forest trail but there was still some nice views. We also had a swim just after the trail crossed the road between Obloke and Koritnica. There also was drinking water there to fill up the bottles
