 The first season is ice season, which starts usually in mid-January and lasts till mid-April.During this season ice depth increases up to 140 centimeters, that allows safe vehicle driving on the ice cover (except heavy vehicles, such as tourist buses, that do not take this risk).This allows access to the figures of ice that are formed at rocky banks of Olkhon Island, including Cape Hoboy, the Three Brothers rock, and caves to the North of Khuzhir.
