The Serengeti, which means “endless plain”, lives up to its name. Famous for its abundance of wildlife, it is perhaps best known for the annual migration of over a million wildebeest and zebra. Here you can watch the herds migrate from the end of June to September and from November to February. The Ngorongoro Crater was once a huge active volcano - probably as big as Kilimanjaro. After the eruption, the cone collapsed, leaving behind the caldera, which is over 10 km wide and is home to an estimated 30,000 animals.
