It is the "valley" route that started at the Moroznaja ski resort. Take a taxi from Elizovo to Moroznaja ski resort (7 km).
It is forgotten route (1). Only first part is some kind of footpath, then it is over after rope bridge over the river Polovinka. In this area huge building of cottages for tourists is now, and tourist companies took them to so-called "Blue lakes", and the bridge is just left to these "domiki" (cottages). Then, you have to continue on the left embark of the river that flow into the Polovinka river. Near its spring you go out from the stone birch forest and ascend through the rocky slopes to the pass and then to the summit.

In last part of the route you need crampoons, avalanche safety equipment, and probably ice-axe during the winter. During the summer only troubles with free stones near the summit.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
