Crimea is a peninsula on the northern coast of the Black Sea in Eastern Europe that is almost completely surrounded by both the Black Sea and the smaller Sea of Azov to the northeast. It is located south of the Ukrainian region of Kherson, to which it is connected by the Isthmus of Perekop, and west of the Russian region of Kuban, from which it is separated by the Strait of Kerch though linked by the Crimean Bridge. The Arabat Spit is located to the northeast, a narrow strip of land that separates a system of lagoons named Sivash from the Sea of Azov.
