Are you looking for an extraordinary trip? A great adventure? This trek is in total autonomy, your pack is in a sled which you pull behind you, you walk, eat and sleep on the ice. You are also immersed in the notoriously unpredictable siberian weather (snow, wind, windstorms...). Even if usually in march there are many sunny days, nights remain cold. In return for your efforts, you will experience unforgettable emotions and memories! This trip is a complete 180k loop around Olkhon Island (the largest island in lake Baïkal), and a chance to see its most beautiful places. On the way, the cab1in which was built for the film « In the siberian forests», adapted from Sylvain Tesson's book. Not only will you see the cabin, but we'll spend a night in it, and light a woodfire.
