This is a difficult trail both going up and coming down. We started at the Alpina Blazna Lodge, on the route to the former mine. You have to carry the bike for the last 2 km of the climb, walking among the blueberry bushes. The descent is marked with the blue cross marking, down to the top of the ski slide. From there down to the Alpina Blazna Lodge the trail goes on the ski slide.
