Few sites will have toilet facilities, but the site at Bejrawiya does. The toilet is just a hole in the ground, but it is kept clean. However there are no facilities for washing your hands, nor toilet tissue provided. Therefore, it is advisable to take either a toilet roll or moisturised wipes when travelling anywhere outside the capital or the larger towns.
The monuments at Begrawiya are quite fragile, although over two thousand years old. Early explorers deliberately damaged the tops of the pyramids in search of treasure. Adventurers and visitors have carved their names into the blocks, sometimes even defacing ancient carvings.
I know of some enlightened visitors [supposedly] who thought it fun to climb the pyramids.
All of these activities are criminal. The Sudanese are trusting and naive where archaeological sites are concerned, If visitors want to be able to visit these places without hassle from uniformed guards, they should respect the monuments.
The sun is particularly strong here, and there is percious little shade available. Make sure you wear a hat and drink plenty of water. Dehydration is extremely unpleasant, and there is nowhere near the site to purchase drinks, so bring it all with you!
With a perpetual lack of funds, the maintenance and upkeep of the site is being hampered by natural forces - the desert is threatening to take over the site! The sand is so fine, it only takes a light breeze to move a few kilo of the stuff - up against the temples.
