The Slovak landscape is noted primarily for its mountainous nature, with the Carpathian Mountains extending across most of the northern half of the country. Among these mountain ranges are the high peaks of the Fatra-Tatra Area (including Tatra Mountains, Greater Fatra and Lesser Fatra), Slovak Ore Mountains, Slovak Central Mountains or Beskids. The largest lowland is the fertile Danubian Lowland in the southwest, followed by the Eastern Slovak Lowland in the southeast. Forests cover 41% of Slovak land surface. Tatra mountains The Tatra Mountains, with 29 peaks higher than AMSL, are the highest mountain range in the Carpathian Mountains. The Tatras occupy an area of , of which the greater part lies in Slovakia. They are divided into several parts. To the north, close to the Polish border, are the High Tatras which are a popular hiking and skiing destination and home to many scenic lakes and valleys as well as the highest point in Slovakia, the Gerlachovský štít at and the country's highly symbolic mountain Kriváň. To the west are the Western Tatras with their highest peak of Bystrá at and to the east are the Belianske Tatras, smallest by area. Separated from the Tatras proper by the valley of the Váh river are the Low Tatras, with their highest peak of Ďumbier at . The Tatra mountain range is represented as one of the three hills on the coat of arms of Slovakia. National parks There are 9 national parks in Slovakia, covering 6.5% of the Slovak land surface.
