  Before the Russo-Ukrainian war the number of tourists visiting Ukraine was eighth in Europe, according to UN Tourism rankings. Ukraine has numerous tourist attractions: mountain ranges suitable for skiing, hiking and fishing; the Black Sea coastline as a popular summer destination; nature reserves of different ecosystems; and churches, castle ruins and other architectural and park landmarks. Kyiv, Lviv, Odesa and Kamianets-Podilskyi were Ukraine's principal tourist centres, each offering many historical landmarks and extensive hospitality infrastructure. The Seven Wonders of Ukraine and Seven Natural Wonders of Ukraine are selections of the most important landmarks of Ukraine, chosen by Ukrainian experts and an Internet-based public vote. Tourism was the mainstay of Crimea's economy before a major fall in visitor numbers following the Russian annexation in 2014.
