This young park is located in Krasnogvardeysky district of the city. Its area is 46.3 hectares. It was opened in 1967 on the site of old residential buildings and a landfill. Trees were planted on the territory, flower beds were arranged, and three reservoirs were cleared. The park was redesigned in 1973 and 1987. In Soviet times, the green zone was traditionally called the Park named after the 50th Anniversary of October. The park received its current name only in 2007.

Small animals live in the ponds, wild ducks and geese fly in. Polyustrovsky Park has a classic layout. Its core is a wide alley, around which the rest of the park infrastructure is grouped. This is a resting place for residents of nearby microdistricts. Children's playgrounds are available, and there is a café in summer. On public holidays, mass festivities and sometimes historical reconstructions are organized. On weekdays, the park area is relatively uncrowded. It was chosen by cyclists and roller skaters. The landscaped area has tracks for their skating and training.

Polyustrovsky Park is located in an ecologically clean area, which belongs to the water protection zone of the horizon of the mineral water deposit. On its territory there is a plant for the production of beverages and the production of mineral water “Polyustrovo”. The name comes from the word palustris, which in Latin means “swamp”. It is said that the history of mineral springs in Polyustrovsky Park began in a very interesting way: even under Peter I, people noticed that residents of Kazachya Sloboda - this was the name of the territory of Polyustrovo — they have enviable health and live a long time. Hoping to solve this mystery, Peter I came here and discovered that it was a unique water with a high content of iron and manganese. After that, the history of the Polyustrovo resort began to develop at a frantic pace — especially supported by the research of a pharmacist who found hundreds of diseases that were treated by Polustrovskaya water. All of Russia comes to Polyustrovo for treatment. In 1898, Alexander Dumas, father, even joined the Russians.
