Step out into the vast open plains of Tanzania and you suddenly feel very, very small. And so you should. You've just joined one of the largest, wildest animal populations in the world. Wildebeest, monkey, antelope, lion, cheetah, crocodile, gazelle, flamingo - they're all out there.
The Tanzania tourist activity is, of course, the safari - but it's entirely up to you whether you do it rough or smooth, or a bit of both. A trek to the top of Mt Kilimanjaro is the pinnacle of outdoor adventure, in more ways than one.
