The Yarkon River in this area is more like a creek than a river, but it is pleasant to walk among eucalyptus trees and water vegetation along the water. Most of this trail forms part of "The Israel Trail".
The trail starts near the parking lot of the Southern Sharon Regional Council ("Mo'atza Azorit Drom Hasharon"), just south of Neveh Yaraq. After a short walk you reach the Yarkon, near the ruins of an old water-pumping station; the water was used to irrigate the citrus orchards which, a few dozen years ago, covered the whole area.
Continue west along the northern bank of the Yarkon until you reach the ruins of Abu-Rabakh flour mills, which used water energy to grind wheat brought from all over the region. Abu-Rabakh was paid in wheat: He charged 10% of all wheat brought to him, but later became greedy and charged 20%!
From here you can either retrace your steps or continue west along the river: The "Seven Mills" recreational area lies a few km further downstream.
This trail can also be done on bicycle.
