The surface from Arandjelovac till a few kilometers before Rogaca is poor at some places but generally ok, while the surface from before Rogaca to the mountain Kosmaj is freshly laid asphalt and is great. The road is generally narrow but the width of the other lane can be used often due to low traffic. It has every type of corner possible from slow to very fast, has a frequent crests and almost no straight making it fun even at slower speeds. However, over crest corners, tractors and some gravel will require you to be at your best.
