The living spine of Africa

From the thunder of the falls, we fly west into the Okavango Delta in Botswana. Worlds apart in look but again carved by water, the land dips into the Okavango Rift Zone, the youngest limb of this tectonic story. Here, the Okavango River spreads its waters not to the sea but into a shimmering inland delta in the shape of a hand (visible from space). Each year, as the rift floor sinks by fractions of a millimetre, the delta cradles floodwaters from the north that sustain grasslands, trees and mammoth anthills that in turn support elephants, lions and hundreds more plains game and wild species.

The floodwaters that pulse through the delta have sustained people for tens of thousands of years—San hunter-gatherers tracing hippo channels and reading the Earth’s heartbeat through reeds and stars. The Okavango is the Great Rift’s soft-spoken twin to Victoria Falls: where one roars, the other whispers, but both exist because the Earth is stretching beneath them.

Traveling north and east, the Rift grows bolder, cutting through high plateaus and down into the rolling grasslands of the Masai Mara. The escarpment is a visible edge of the living spine, a vast corridor guiding the great migrations of wildebeest and zebra in a seasonal journey that echoes the slow movement of the plates and mirrors the planet’s deeper drift. When you watch the herds pour across the Mara, hooves drumming the earth, it feels, quite literally, like an echo of an ancient rhythm and the movement of the Earth itself.

It is in this very place that our own ancestors walked. Fossils in nearby Olduvai Gorge and the Turkana Basin reveal that the first humans rose within this same tectonic scar. The Rift’s alternating wetlands and dry spells honed our adaptability, shaping minds that could plan, cooperate, and imagine.

Farther still, the rift reaches its volcanic crescendo in the Virunga Mountains on the borders of Rwanda, Uganda and the Democratic Republic of Congo. Here magma rises through the wounds of the Earth, forming a chain of dramatic peaks—Nyiragongo, Karisimbi, Mikeno—whose fertile slopes are home to misty rainforests and mountain gorillas. Fire rather than water is the storyteller here, yet it speaks the same tectonic language that carved the falls and molded the delta.

The mountain gorillas, our closest living relatives, mirror in their eyes a lineage that reaches back to those first hominid fossils of the south. The Virungas are a meeting of past and present, a living echo of the kinship between all life shaped by this restless continent. Here, creation and destruction remain inseparable, and the pulse of the Earth beats within every living being it has formed.

Together these four places—Victoria Falls, the Okavango Delta, the Masai Mara, and the Virunga Volcanoes—compose a single continental narrative. Each chapter reveals a different mood of the Great Rift Valley: fracture, subsidence, migration and eruption. The Greatest Safari on Earth℠ is a journey that tells not just the Earth’s story but our own. This is the landscape that carved our rivers, shaped our migrations and tested our resilience. Here, the planet’s deep time meets human time: the slow drift of continents and the spark of consciousness, entwined along one living spine of Africa—where the Earth, and humanity itself, are still in motion.
