In the upper part of the valley, we can spot exposed chalkstone. Birch trees are seen on the valley’s southern bank, while on the northern bank, which is exposed to the sun, there are many thorny shrubs typical of the Carmel, and flowers are still in bloom in the winter. The trail continues through a forest, where we can spot tangled climbing plants and wild aromatic herbs.
Nahal Siah gets its name in Hebrew and Arabic from the frequent hikers. In both languages, it is derived from words meaning “tour” or “hike.” The walk begins on Lotus Street. Descend to the right near the black trail mark, first on the asphalt road and then down the stairs, into the heart of the gully.
