From the Vihren hut to Muratov lake and then to the n.ridge. From the trail the ridge looks more dificult then in reality. It is 2a Bulgarian grade (pD or II). I was alone on the route and on the summit and it was for the first time in my life and I didn't like it. Communication with the partner is the best thing one can find in the mountains
From the Vihren hut I traversed from the summit of Hvoinati Vrah Southwards and continued to climb the Northern ridge. The latter was around 40-45 degrees and, with only walking poles, an axe would have come in handy. On the small summit it was total white-out and quite dangerous. I had orinally intended to descend the south side and loop back to the Vihren hut but given the visibility I decided retraced my steps down the North side.
