100% agree with vundu50 that viewing wildlife on foot is unforgettable.
Also, as has been said, Chitake is set well away from the most visited & famous areas of the park which lie adjacent to the Zambezi. Chitake is tucked under the escarpment & ~1 hours drive from Main Camp.
Up until very recently, Steve Pope ran a fantastic camp in Chitake, but sadly Steve died earlier this year. I am not now aware of any tour operators running camps here.
There are 2 remote wilderness camps in are area run by National Parks but you have to be totally self-contained to stay here.

So, camping at Mana is certainly not for the faint-hearted.
