Fly straight into the natural wonder that is called the Ngorongoro Crater, and descend into its wonderous caldera straight after arrival. The caldera of Ngorongoro is the biggest in the world which is both inactive and not filled with water. With ten miles across, the crater flatland is home to approximately 25,000 animals at any given time. Lions, rhinos, zebras… you name it. The only animal missing is the giraffe, whose long legs hinder it from descending into the caldera.
