The waterfalls you are talking about sound amazing, imagine sliding on smooth rocks!
I am also jealous of your brother, Valley of the Kings! wooooooooooooow so luckyyyyyyyyyyy. They were a culture unlike anything else. I wish the tv makers could do a series like Vikings, all historic (also fiction) but with the egyptians instead.
One day for sure we will meet. May take some time but it will happen ^_^
