The Vistula Spit (Polish: Mierzeja Wiślana; Russian: Балтийская коса; German: Frische Nehrung) is an aeolian sand spit, or peninsular stretch of land, which separates Vistula Lagoon from Gdańsk Bay in the Baltic Sea. The border between Poland and Kaliningrad Oblast, an exclave of Russia, bisects it, politically dividing the spit in half between the two countries. The westernmost point of Russia is located on the Vistula Spit.
