The Pieniny Klippen Belt stretches over 550 kilometres from western Slovakia to the Laborce valley in the east. The Pieniny Mountains are a distinct mountain range (35 kilometres long and 6 kilometres wide) in the centre of this belt. The Dunajec river ravine divides the range into three parts:
The most attractive part of the mountain range, from both a natural and scenic point of view, is the Pieniny Właściwe range. The peaks here are beautifully jagged and the valleys often form rocky gorges. The northern mountain faces slope gently into the valleys, whereas the southern and eastern picturesque limestone cliffs (which are up to 300 metres high) drop down suddenly to the Dunajec river.
