One of the reasons why the Ngorongoro Highland Trek is so expensive is, among other things, the camping fees and the number of people/donkeys escorting you. You are camping in special campsites, which are twice the price of normal campsites. A well-trained guide will be escorting you together with an armed ranger from the Ngorongoro Conservation Area Authority, and Maasai warriors and donkeys (to carry your supplies).Â
