There is the frontier of Slovakia and Poland in the north. The highest hill is Gerlachovsky peak (2655m) situated in the centre of TANAP. In the west it is Krivan (2494m) which  dominates and in the east it is Lomnicky peak (2632m). There are 25 peaks between Krivan and Lomnicky peak whose altitude is over 2500 m. The point whose altitude is the smallest is situated in the south-west part of the park (620m). High Tatras and West Tatras are consisted of granite. East Tatras (Belianske Tatras) are especially consisted of Triasic limestones and dolomits. In the past there were glaciers. Almost every valley in the Tatras was modified by these glaciers (for example the valley Rohacska dolina, the valley Ziarska dolina, the valley Velka Studena dolina and the valley Mala Studená dolina). The water is very important here. More than 600 millions m3 of water is taken away by the brooks during the one year. Ground water is also a big source of water. There are about 110 lakes. Their area is 3 km3 and the bulk is about 10 000 m3. Hincovo pleso is the largest and the deepest (20,08 ha and 53,2 m). There are also several waterfalls ( or example the waterfall Skok, the waterfall Velky vodopad and the waterfall Studenovodsky vodopad). There is a cold climatic area with inland climate. The winter is cold here and the summer is warm  with precipitation. The average temperature of the year is -3,7° at Lomnicky peak and 5,8° in Poprad. The flora and the forests are very various. There are about 1300 species of higher plants, about 900 species of folds, 700 species of lichens and more than 500 species of mosses. About 40 species of plants grow in the altitude over 2600 m. Not every plant has the same origin. There are different endemits: the Carpathian ones, the West Carpathian ones or the endemits from Tatras. In the forests there are beeches, fir trees, pines, mountain ashes and the others. Dwarfed pines grow in the altitude of 1800 m. There is also a fern or a red whortleberry (and the others) and coloured snow. Its colour is caused by the certain species of folds or microorganisms (for example Chlamydomonas nivalis, Coliella tatrae, Rhizocarpon or Acarospora oxytona). There are several law  protected plants. The animal kingdom in Tatras is as different as the flora. Several species survived since the period of glaciers. There are some Carpathian endemits (fieldmouse, eagle, lizard and the others). Different species of owls (for example eagle-owl), carnivorous animals (falcon, raven and the others), small beasts of prey (weasel, polecat, marten or cat), big beasts of prey (bear, lynx, fox, wolf), and the deers, the roe-bucks, etc. live here, too. In the bigger altitude there is chamois and marmot (law protected). Their number diminishes as the number of visitors augments. Today there is about 500 chamois. In the year 1978 there were 14 bears, only 2 wolves and only 6 eagles (law protected). The number of the others diminishes, too.
