This region in the south of Ukraine stretches out along the northern coast of the Black Sea. Its largest cities are Odesa and Mykolaiv. Most of the key Ukrainian seaports responsible for exports are located here. This forest-steppe region is fascinating not only for its coast but also for the area where the rivers flow into the sea, scattered with many estuaries, reed beds, and sand spits. Prychornomoria is known for its ship-building industry, yacht clubs, and rafting competitions. Artefacts of the once-prosperous Greek colony Olbia have been preserved near the village of Parutyne. The natural complex of the Aktovskyi Canyon, Buzkyi Hard National Nature Park, and Tylihul Estuary and its ornithological sanctuaries are famous among tourists. Prychornomoria is also one of the wine-making centres of southern Ukraine.
