Olkhon (Russian: Ольхо́н, also transliterated as Olchon; Buryat: Ойхон, Oikhon) is the third-largest lake island in the world.

There are two versions regarding the origin of the name of the island and both are derived from the language of the Buryats, the indigenous people of Olkhon.

The village of Khuzhir is the administrative capital of Olkhon, designated as such in April 1987 when the Soviet government issued a comprehensive decree protecting Lake Baikal.

Due to an increasing number of tourists from all over the world, many residents work in this sector as well, and tourism has become an important part of the economy in Olkhon.

[5] On the western coast, close to Khuzhir, is Baikal's most famous landmark, the Shamanka, or Shaman's Rock.

Natives believe that Burkhan, a modern religious cult figure of the Altai peoples, lives in the cave in this rock.

The museum at Olkhon, named after Revyakin, has exhibits on the nature and ethnography of the island, including pipe-smoking and a samovar collection.

The National History Museum of Revyakin N. M[7] in Khuzhir contains collections of historical items linked to the life and culture of the people of Olkhon from Neolithic times to the present day.

The Revyakin Museum was originally named after a famous geologist, paleontologist, geographer and writer of science fiction, Obruchev.

[9] Three Brothers Rock, or Sagaan-Khushun Cape, is one of Baikal's natural monuments and another popular tourist sightseeing spot.

The brothers were extremely happy with their newly gained freedom as eagles and decided to fly around the island after promising not to eat dead meat.

The wall is probably one of the best preserved ancient structures of the island and is composed of large stones without the use of any binding materials.
