The Serengeti is a must-see excursion, and the tour operators know it, they overcharge with my three days trip costing $525. We even had to bring our own tents. Still these nowhere on this world like it, the vast grass plains stretching over 12,000 square miles treated us to numerous elephants, lions, giraffe, wildebeest, antelope, and three leopards. This is the best part of a 2-month trip through Africa.
