Jeziorak holds the record as the longest lake in Poland, measuring over 27 kilometers from end to end.
The island of Wielka Żuława is the largest lake island in the country, spanning roughly 82 hectares.
The lake is physically linked to the historic Elbląg Canal, famous for its unique system of inclined planes where boats travel over land.
The entire lake sits within the boundaries of the Iława Lake District and is part of the larger protected Iława Landscape Park.
Several islands on the lake, including Czaplak and Wielka Żuława, are classified as protected archaeological or ecological zones.
Jeziorak is the longest lake in Poland, stretching approximately 27 kilometers through the Iława Lake District. It is defined by a highly irregular shoreline, numerous coves, and 16 islands, the largest of which is Wielka Żuława. The lake acts as a vital segment of the Elbląg Canal, a historic 19th-century waterway connecting the lake to the Vistula Lagoon. Its waters are categorized as a protected landscape area, supporting diverse aquatic flora and fauna. The lake features depths reaching up to 12 meters in its deepest sections. Navigation is facilitated by a network of marked sailing channels, making it a primary destination for inland water sports. The surrounding terrain is dominated by dense coniferous and mixed forests, particularly the Iława Landscape Park.
