We two were on Raduha yesterday. We drove towards Koča na Loki, but when we reached the gravel section we continued another 2 km on the road, then too much snow on the road and no other car tracks, so we turned around, left the car a bit lower at the sign saying 1.5 hrs to Loki and went on foot on the path. Still some snow on Raduha but excellent trip.☺
