Ukraine is a destination on the crossroads between central and eastern Europe, between north and south. It borders Russia and is not far from Turkey. It has mountain ranges – the Carpathian Mountains suitable for skiing, hiking, fishing and hunting. The coastline on the Black Sea is a popular summer destination for vacationers. Ukraine has vineyards where they produce native wines, ruins of ancient castles, historical parks, Orthodox, Catholic and Protestant churches as well as a few mosques and synagogues. Kyiv, the country's capital city has many unique structures such as Saint Sophia Cathedral and broad boulevards. There are other cities well known to tourists, such as the harbour town Odesa and the old city of Lviv in the west. Most of Western Ukraine, which used to be within the borders of the Republic of Poland before World War II, is a popular destination for Poles. Crimea, a little "continent" of its own, had been a popular vacation destination for tourists for swimming or sun tanning on the Black Sea with its warm climate, rugged mountains, plateaus and ancient ruins, though the tourist trade has been severely affected by Russia's occupation and annexation of the territory in 2014. Cities there include: Sevastopol and Yalta – location of the peace conference at the end of World War II. Visitors can also take cruise tours by ship on the Dnieper River from Kyiv to the Black Sea coastline. Ukrainian cuisine has a long history and offers a wide variety of original dishes.
