On Africa's Great Plains, the pulse beat of the planet reverberates. Our Land Cruiser is a tiny island in a vast, grassy sea, its idle drowned out by waves of pounding hooves. Wildebeest and zebra flow in a living current across the Serengeti as lion and cheetah follow in their wake, finely tuned hunting machines ready to stalk and take down the weakest members of the herds. From our private mobile camp stationed in the center of the world's greatest ancient migration route, we are subsumed in a primal spectacle as the drama of predator and prey unfolds. Witness it in rare seclusion, immersed in the wonder of one of the world's truly epic wildlife events. And of course, no Tanzania safari is complete without a descent into the famed Ngorongoro Crater. The largest unbroken caldera on Earth, the crater is home to nearly 30,000 animals sustained within its walls.
