One of the most mysterious places on Sakhalin is considered to be the remains of the Frog, located in the area of the residential quarter Vestochka.
Remnants are isolated rock masses that have survived the destruction of a higher mountainous country due to the influence of any exogenous factors, primarily weathering and erosion.
Its mystery attracts not only local residents, but also visitors to the island. Due to its shape, the mountain actually resembles a sitting frog preparing to jump.
In 1983, the Frog rock was recognized as a state natural monument of regional significance.
The Ainu revered the Frog as a Temple of wisdom. In our time, the unusual properties of the remnant remain-it is recommended to come here to resolve issues of choosing a life path. Climbing the path to the Temple of wisdom, a person as it were relives his life, eventually realizing the true purpose and goals. And modern psychics in one voice say that the remnant is not just a beautiful rock, but "its essence manifests itself through three levels: the sky, ground and underground, as well as the life cycle of the frog itself: it is born in water, jumps on the ground and buries itself in the silt for the winter".
