The main channel of Nahal HaBesor begins its path near Sde Boker, crosses the mountains of the Northern Negev, undermines the hills of the Negev plain near Revivim, twists through the loess soil of the Western Negev and ends its journey after approximately 80 km in Gaza. The main tributaries of Nahal HaBesor are Nahal Grar and Nahal Be'er Sheva.
The immense floods that the river brings with it, mainly by means of its tributaries that originate in the Judean foothills and in Mount Hebron, create natural springs in the western Negev. Small settlements already existed around these springs in prehistorical times. The largest of these springs – Einot HaBesor (the Besor Springs) – is the basis for the Besor National Park (Park Eshkol).
In the Western Negev three sections of scenic roads with a total length of approximately 45 km accompany Nahal HaBesor. The roads are traversable for a private car and provide every visitor with opportunities to get to know the river's scenery and the sites along it well. The roads are marked and the main sites along them are signposted, the fruit of collaboration of the Shikma-Besor Drainage Authority, KKL-JNF, the Israel Nature and Parks Authority and Eshkol Regional Council. Before setting out, one small request: the land on the banks of the river is cultivated and adds its beauty to the scenery. Please, do not damage the fields and do not pick the crop of the orchards.
