A elephant steps to the water hole at dusk, close enough that you can hear it drink. That’s your view from the infinity pool at Four Seasons Safari Lodge Serengeti — and it sets the tone for everything that follows. This trip moves through three distinct landscapes: the open plains of the Serengeti, the dense wildlife bowl of Ngorongoro Crater, and the coral-fringed coast of Zanzibar. Time it for June through August and you catch the Great Migration. Wildebeest cross the Mara River in columns that stretch to the horizon. You don’t rush past it. Alp Travel Co. builds in the time to stay, watch, and go back the next morning. From the savannah you drop into the crater, then fly east to Zanzibar. Each stop asks something different of you. Each one delivers.
