Off Tarmac diversion in Sudan
If you are bored of the new tarred road down the nile then try visiting the Naqara temples South-West of the Meroe pyramid site. (the pyramids are unfortunately now behind an oil pipeline - incredible they just ran the pipeline directly in front of a monument like that, but that's Sudan...
The temple is reached by turning South off the tarred road - there doesn't seem to be a real piste, just head out into the sand following the GPS and you'll get there - there are various car tracks, but each driver seems to have their own route. The temple is at N16. 16' 07" - E33. 16' 35" - you can see it on Google Earth. There is also a deep well - 100m deep, which presumably supplied the temple and now supplies the local goats. Well worth the drive down from the tarmac, and it will probably be just you and a couple of goatherds there.
