Jeziorsko Zaspy is an access point to the Jeziorsko reservoir, the large artificial lake on the Warta River in the Lodz Voivodeship. The Zaspy spot is located on the southern part of the reservoir. The reservoir covers about 42 km² and offers vast sailing areas. The water is shallow in some areas. Conditions range from flat water to moderately choppy depending on the wind. Winds from all directions work thanks to the size of the lake. It is a popular spot for riders from Lodz and central Poland.
