A bottomless lake of course has a bottom, this lake) But earlier the lake was so deep that the locals, who could not determine its depth, called the lake bottomless. Lake of the Bottomless was considered holy and attracted a lot of pilgrims. Next to him grew an oak tree, which according to legends, had miraculous properties. Now it is a resting place in the reserve, at the beginning of the ecological trail. There are gazebos around the bottomless lake, there are barbecues and places for outdoor games.
