Neva Bay
Vasilyevsky Island is the largest island (not counting the unnamed artificial island formed by Obvodny Canal and Fontanka and Kotlin Island (the site of Kronstadt) in the Neva Bay), followed by Petrogradsky, Dekabristov and Krestovsky Islands. The latter, together with Yelagin and Kamenny Island, forms the so-called Kirovskiye islands, covered mostly by parks.
