Across the border in Tanzania, the Serengeti National Park continues this incredible ecosystem with even larger expanses of open plains. Here, millions of wildebeest and zebra follow ancient migration routes, attracting predators and creating one of the greatest wildlife spectacles on Earth. Not far away, the Ngorongoro Crater—a UNESCO World Heritage Site—provides a natural amphitheater for wildlife viewing. This vast volcanic caldera shelters a dense concentration of animals in a stunning setting, making it a must-visit alongside the Mara and Serengeti for anyone seeking a classic East African safari experience.
