The region of the Fourth Cataract, the most impassable of all rapids of the Nile. Still today the water rapids cannot be crossed by any large boats making the region accessible only via a sandy and rocky desert track. The region is among the most neglected areas in Northern Sudan. Apart from basic educational institutions virtually no public infrastructure such as tarred roads, bridges or ferry boats and hospitals exist.
