Chornohora range is the highest mountain range of the Ukrainian Carpathians. The main range stretches approximately 40 km between the rivers Chorna Tysa (Black Tysa) in the west and Chorny Cheremosh (Black Cheremosh) in the east. Chornohora possesses all the highest mountains in Ukraine, so-called «two-thousanders» (the mountains above 2000 meters asl). The Ukrainian «two-thousanders» include 6 peaks, namely Hoverla (2061 m), Brebeneskul (2036 m), Pip Ivan (2028 m), Petros (2020 m), Hutyn Tomnatyk (2016), and Rebra (2002 m). In the mid-war period, Chornohora was a state border between Czechoslovakia and Poland, who gained independence after the disintegration of the Austrian-Hungarian empire. Here, you can still find the trenches of WWI and the burial places of the Ukrainian Insurgent Army, operating on these territories during and after WWII. Now Chornohora serves as an administrative boundary between Ivano-Frankivsk and Zakarpattya regions of Ukraine.
