Set out into the Ngorongoro Conservation Area, centered around an enormous volcanic caldera where animals of all kinds gather to graze or hunt. Spot buffalo, wildebeests, zebras, and gazelles as they bound across the grass. Delve into the story of human origins at the Olduvai Gorge Museum and Visitor’s Center, located near the site where National Geographic archaeologists Louis and Mary Leakey discovered early hominid fossils and stone tools. After lunch, continue to the world-famous Serengeti National Park and go on a safari across the wild Serengeti Plain, keeping an eye out for galloping giraffes and lounging lions; then settle into our tented camp under the setting sun.
