Guess it depends what you're after - Ziwani in Tsavo, Kenya, near the border of Tanzania is the most incredible spot that I've been to. Thirteen tents by hippo pools in the middle of nowhere - no running water and electricity for two hours a day - the sun sets over Kilimanjaro - heaven on earth .... (Although I don't think I went to the loo the whole time we were there - who
knows what was lurking in that long drop!!
