Shilo Stream, winding its way from the Samarian hills to the Yarkon River, spans 50 kilometers. In the winter months, it transforms into a vibrant watercourse, characterized by robust flows and occasional flash floods, creating a captivating natural display. This stream, although seasonal, is significant, contributing about a quarter of the Yarkon River's drainage basin.

Emerging from the Shilo Valley, 700 meters above sea level, in a region steeped in historical and geopolitical complexities, Shilo Stream navigates through a landscape marked by contention. Its upper reaches meander close to the Israeli West Bank barrier, traversing areas under varying degrees of Palestinian and Israeli control, necessitating cautious exploration, often with armed accompaniment for safety.

The stream's ecological value is profound, forming a natural corridor that links the Samarian highlands to the coastal plains. The water's distinctive white-brown tint is a result of its journey past chalk quarries, a testament to the area's rich geological activity. As it meanders westward, it merges with Mazor Stream near the southern foothills of Migdal Tzedek National Park, close to Rosh HaAyin, before joining the Yarkon River.
