=Wadi Naait=[92] is a narrow tortuous gorge, with a sandy floor shut in by high hills, coursing eastward to the coast plain a little south of the 24th parallel. Though only a small wadi some sixteen kilometres in length, it is well known because it forms the usual road from Wadi Lahami to Berenice. Its actual head has not been surveyed, but lies probably between the mountains of Um Gunud and Um Hegilig. Its principal feeders are =Wadis Um Sumer= and =Abu Marwa lil Naait=, which enter it from the north-west, and =Wadi Abu Ghalqa=, entering from the north and draining the granite hills called Gebel Abu Ghalqa. All three of these feeders enter Naait near together, some ten kilometres before it emerges on the plain; the lower part of the wadi is free from lateral branches. The fall is ten metres per kilometre among the hills. On emerging from the hills on to the sandy coast plain, it joins an ill-defined drainage line called =Wadi el Mukhit=, which enters the sea at Port Berenice, some fifteen kilometres further east. The name Wadi el Mukhit is also given to other ill-marked drainage lines entering Port Berenice from the sandy tract between the hills of the main land and the hills of the peninsula of Ras Benas. Some three kilometres north-east of the mouth of Wadi Naait, on the coast plain, is a conspicuous isolated low hill, forming a well-known landmark and called =Grain el Rih=. The plain drained by Wadi el Mukhit is a dreary sandy waste, and the crossing of it in a high wind is very trying by reason of the immense clouds of sand raised and carried in the air.
