The Ngorongoro Crater, the largest unbroken volcanic caldera in the world, is a UNESCO World Heritage Site and a natural wonder. Its enclosed ecosystem is home to a dense population of wildlife, including the Big Five—lions, elephants, leopards, rhinos, and buffaloes. Visitors can also witness vibrant flamingos on the crater’s soda lake and experience the unique coexistence of wildlife with the Maasai people who graze their cattle on the crater’s rim.
