Lithuanians respected trees, including oaks, for several reasons: the tree and its life were compared to man and his life; the trees were the former abodes of spirits and gods; the healing properties of trees; the ghosts of the ancestors lived in the trees. Such a cloudy, wild, natural forest is hidden by the cognitive nature path of Ąžuolija Reserve. Nature paths in the Ąžuolija Botanical and Zoological Reserve, allow visitors to get acquainted with the original oak trees in the deciduous forest of the northern subzonal forests of Central Europe, the ephemerides blooms in the spring, the abundance of colours in the fall, and the natural diversity of the natural stream. The area of the oak forest is more than 300 ha. The botanical-zoological reserve occupies 68.2 ha of this forest area. The length of the path winding through the reserve is two kilometres. It is not easy to walk on it: the path is not paved with wooden boards or other types of pavement, the slopes are steep, a springy stream, fallen trees that need to be climbed, low floodplains and other paths of the old forest.
