Main image

The Zegrze Reservoir (Jezioro Zegrzyńskie) is a man-made lake in Masovian Voivodeship, Poland, formed on the Narew River near the village of Zegrze. It is a prominent recreational water body for the Warsaw metropolitan area.

The reservoir offers beaches, marinas, and facilities for sailing, windsurfing, and motorboating; several clubs and rental operators serve water-sport visitors. Shoreline roads and paths are used for cycling and walking, and small lakeside towns provide restaurants and accommodation for weekend visitors.

The reservoir was created by damming river flows to improve water management and to provide a recreational resource for the growing Warsaw region. Since its creation it has been managed for both utility and leisure purposes.

Zegrze Reservoir sits north of Warsaw in the Masovian plain, within easy driving distance from the capital. It lies near the towns of Zegrze, Nieporęt, and Serock and is surrounded by low-lying agricultural and suburban areas.

  • Distance from Warsaw: Located roughly 20-30 kilometers north of central Warsaw, making it a popular day-trip spot for city residents.
  • Activities: Popular for sailing, windsurfing, and shoreline recreation, with several marinas and water-sport operators on the reservoir.

How to Get to Zegrze Reservoir #

From Warsaw, head north on DK61/E77 toward Legionowo and Serock (roughly 30-50 minutes by car depending on traffic). Regular commuter trains and buses run to Legionowo; from there local buses and taxis serve the reservoir towns. Cycling paths link parts of the western shore to Warsaw suburbs for adventurous riders.

Tips for Visiting Zegrze Reservoir #

  • On warm weekends the western beaches fill; head for the northeastern shore near Dębe and Nieporęt for quieter coves.
  • Take a small ferry or rent a motorboat to see the reservoir from the water-the scale reads differently from a boat than from the shore.
  • Arrive early on windless mornings for mirror-like water and an easy walk along the broad promenade in Serock.
