The park is located in north-eastern Slovakia. It covers the eastern Pieniny Mountains on the border with Poland. The Pieniny Mountains as a whole, cover an area of more than 100km2. The eastern part of it is situated on the territory of Slovakia, the western half belongs to Poland. The valley of the Dunajec river marks the border between Slovakia and Poland. The Pieniny Mountains are not particularly high, especially in the western part of the range. Though this is somewhat disguised by the extreme dissection of the landscape, especially around the Dunajec river gorge. Along this canyon, the highest point on the Slovak side is the Holica mountain with 828m. The highest point in the national park is Vysoké skalky at 1050m. Vysoké skalky is located in the Lesser Pieniny range, which forms a boundary ridge between Slovakia and Poland, consisting of several smaller cliffs. In the south and southwest, bordering the Tatra National Park, the protective belt reaches the Popradská kotlina basin and the Ždiarska brázda furrow.
