Ergaki Nature Park is centred on Western Sayan Mountains, where granite spires, clear lakes and dense Siberian forest form a compact mountain park in the Western Sayan. The strongest reason to make the journey is to see the hanging stone above lake raduzhnoye.
Many visits to Ergaki Nature Park begin with the experience described as “See the Hanging Stone above Lake Raduzhnoye”. The more revealing question is why it exists here, how people used the surrounding ground and what remains visible from earlier phases. A huge granite block appears balanced on a steep slope; reaching the viewpoint links forest, lake and one of Siberia's most distinctive rock forms.
At Ergaki Nature Park, the physical story begins with the structure of the ground. Ridges, valleys and changing elevation create several distinct micro-landscapes. The strongest views usually require an early start and enough time to continue beyond the first accessible viewpoint.
Relief controls far more than the view. At Ergaki Nature Park, “Hanging Stone” reveals how elevation divides vegetation, weather, water and the routes available to people. A giant boulder seems poised above the valley.

Human history
Lives shaped by the terrain
Ergaki's granite ridges were shaped by uplift, glaciation and intense frost weathering, producing the sharp profiles now known as the Sleeping Sayan and Bird peaks. The surrounding Sayan region has long been used by Indigenous and pastoral communities moving between forest and high summer ground.
Soviet-era mountaineers and local outdoor clubs established camps and routes, while road construction along the Yenisei corridor made the western Sayan more accessible. Ergaki Nature Park was created in 2005 to manage increasing recreation and protect mountain ecosystems.

Turning point
The change that redefined the place
The park formalised trails and camps but also concentrated visitors in fragile lake basins. Its modern history is therefore one of rapidly expanding domestic tourism in a landscape whose granite forms had previously been reached mainly by local users and climbers.
