Bosnia has also become an increasingly popular skiing and Ecotourism destination. The mountains that hosted the winter olympic games of Bjelašnica, Jahorina and Igman are the most visited skiing mountains in Bosnia-Herzegovina. Bosnia and Herzegovina remains one of the last undiscovered natural regions of the southern area of the Alps, with vast tracts of wild and untouched nature attracting adventurers and nature lovers. ''National Geographic'' named Bosnia and Herzegovina as the best mountain biking adventure destination for 2012. The central Bosnian Dinaric Alps are favored by hikers and mountaineers, as they contain both Mediterranean and Alpine climates. Whitewater rafting has become somewhat of a national pastime in Bosnia and Herzegovina. The primary rivers used for whitewater rafting in the country include the Vrbas, Tara, Drina, Neretva and Una. Meanwhile, the most prominent rivers are the Vrbas and Tara, as they both hosted The 2009 World Rafting Championship. The reason the Tara river is immensely popular for whitewater rafting is because it contains the deepest river canyon in Europe, the Tara River Canyon.
