The base of this caldera has become a veritable 'Garden of Eden', where thousands of animals cohabit, and Maasai herd their cattle alongside predators and prey; see giant-tuskers, black-mane lions, 6,000 wildebeest, black rhino, cheetah and flamingoes turning the soda lakes pink. Game drives descend from the rim in the morning and usually last all day, with a picnic lunch.
