See how the Maasai, among the last of the world’s pastoral peoples, are adapting to the 21st century in their own way and in their own time. Around 12 distinct groups of Maasai remain in the world, the largest of which now lives in Tanzania. Visit Engaruka, the lost city in the shadow of the Great Rift Wall, where Maasai mix irrigation, farming and traditional herding. In Mkuru, near Arusha National Park, short camel treks with local Maasai give visitors a glimpse into nomadic culture, as they climb nearby Ol Donyo Landaree.
