Some Polish geographers state that the Slovak part of the Radziejowej Range can be linked with the Ľubovnianska vrchovina, the name Lubowelskie Upland is also used.

The agreed boundary between the Radziejowej Range and the Slovak range is carried through the valley from Poprad of the river Czercz, through Gromadzka Mountain Pass and the valley of the stream Wielki Lipnik.

[7] According to the regionalisation by Jerzy Konradzki of physio-geographic Poland from the West of Beskid Sądecki is the valley of the Dunajec which separates the mountain range from the Gorce Mountains, and from the North-Western point from the Island Beskids.

The South-Western border with the Pieniny is made by the Dunajec, the Grajcarek valley, Biała Woda and Rozdziela Mountain Pass, the limestone rocks in the Northern part of the river bed of the Biała Woda, mean that actually this region should belong to the Małe Pieniny.

The only other large river which lies in the region is the Poprad, when the Dunajec flows from the West and South, forming the border of the mountain range.

In the Beskid Sądecki mountain range there are not many artificial water reservoirs, there are small barrier lakes on the ridges, an example of is the Młaka which is located in the Baniska Natural Reserve.
