Wadi Ferrah 

Wadi Ferrah meets Wadi Arbaein at the foot of Gebel Ferrah. It borders Mount Sinai and Ras Safsafa whose slopes rise up on the north east. A small ibex population drifts along these slopes. The ibex is threatened in the St Katherine Protectorate due to over-hunting and their sensitivity to disturbance.

Wadi Ferrah continues into Wadi Shrayj. From the beginning of Wadi Shrayj one has a spectacular view over Wadi el Raha, the large plain at the crossroads to the monastery and the village, where one beliefs the people of Israel waited for Moses to return from Mount Sinai.

The ruins of several ancient dwellings from the Nabatean (200 BC - 100 AD) and Byzantine (300 - 700 AD) periods can be seen in Wadi Shrayj. The Byzantine buildings are built without using any mortar, have low entrance doors, small windows at various heights, shelves and niches built into the walls. Traces of ancient water conduits can also be found, which were used to direct rain water from the mountains to the settlement using as base natural granite drainage lines.
