The easiest way to spend the night at Lake Baikal is to spread out the sleeping bag and to pitch one's tent. Several people try their luck by asking locals for accommodation. They can often spend the night in a typical siberian framehouse for a small fee.
Not far from Kultuk in the small village Angasolskaja there is a small trubasa. From the cabin you have great views over Lake Baikal and the old transsiberian line section. It has some shared rooms, a small kitchen, a typical russian washing room and a toilet with views over the lake.
The housing estates Schumucha and Ulanowo offer some more accommodation facilities.
You may also find an overnight stay about 10 kilometres south of Port Baikal. In Port Baikal there are a lot of cheap accommodation facilities, especially since the old transsib line section has been put into operation again. The most curious places the spend the night are probably old transsib railway-cars.
