Location
The northern border of the island is the waters of Gdańsk Bay, while its southern border is a branch of the Vistula river, called the Martwa Wisła. The western border was created in 1840 during the flooding and creation of a new mouth of the Vistula called Śmiała Wisła. The eastern border was dug in 1895 as a new, artificially created mouth of Vistula, called Przekop Wisły.

In Górki Wschodnie is located a bird reservation and a center for research on birds.

Sobieszewo Island is one of the 34 quarters of Gdańsk.
