The Great Rift Valley, part of the wider East African Rift System, stretches roughly 6,400 km from Jordan in southwestern Asia through East Africa to Mozambique, formed over some 30 million years as the African and Arabian tectonic plates slowly pull apart. Within East Africa, the rift splits into two great arms, the Eastern and Western branches, shaping much of the region’s landscape, lakes and wildlife habitat.
The rift at a glance
- Part of a rift system roughly 6,400 km long, averaging 48-64 km wide
- Forming for around 30 million years as tectonic plates separate
- Splits into Eastern and Western branches across East Africa
- Responsible for volcanic peaks including Kilimanjaro and Mount Kenya
Two branches, two landscapes
The Eastern branch runs through Kenya and Tanzania, holding lakes such as Turkana, Naivasha and Magadi, along with the volcanic highlands that shape much of Kenya’s safari country. The Western branch arcs north from Lake Nyasa through Rwanda, Uganda and the Democratic Republic of Congo, holding the deep, elongated lakes Tanganyika, Kivu, Edward and Albert, and forming the dramatic escarpments that frame western Uganda’s parks.
A landscape that shapes East African safaris
Much of what defines a classic East African itinerary traces back to the rift: its volcanic soils support the grasslands of the Serengeti-Mara ecosystem, its escarpments create the dramatic backdrops of parks like Queen Elizabeth and Lake Manyara, and its lakes provide some of the region’s richest birdwatching. Escarpments along the rift’s edge drop more than 2,700 m in places, giving many of East Africa’s best viewpoints their striking sense of scale.
Where to experience the rift
- Kenya’s Rift Valley lakes, including Naivasha, Nakuru and Turkana
- Western Uganda’s Rift Valley floor around Queen Elizabeth National Park
- Rwanda’s Lake Kivu and the Virunga volcanoes along the Western branch
Practical information
- The rift underlies destinations across Kenya, Tanzania, Uganda and Rwanda rather than being a single site to visit
- Best appreciated through its individual lakes, escarpments and parks rather than as one stop
- A useful frame for understanding why East Africa’s landscape varies so dramatically over short distances
The Great Rift Valley is the geological backbone of an East African safari, connecting many of the region’s most iconic destinations.
