Tsavo East & West

Combined, Tsavo East and West form one of the largest protected wilderness areas on the planet — 21,000 square kilometres of semi-arid bush, volcanic terrain, and riverine ecosystem bisected by the Nairobi-Mombasa highway and the Standard Gauge Railway. The scale of Tsavo is the first thing it impresses upon you: the horizon extends in every direction, vehicle density is a fraction of the Masai Mara, and the sense of genuine, unexplored wilderness is among the strongest in Kenya. Tsavo is the safari for travellers who have done the more famous parks and want the wildlife without the crowds.

Tsavo East's defining characteristic is its red elephants. The iron-rich laterite clay of the semi-arid plains, churned up by elephants dusting and wallowing, coats their grey hides in a russet red that becomes more vivid as the dry season progresses. A herd of red elephants moving across the Galana River flats against the pale blue sky of the dry season is one of the most distinctive wildlife images in Africa. The park's flat terrain and the Galana River concentrate wildlife in the dry season in patterns that make game drives productive. The Yatta Plateau, one of the world's longest lava flows, provides elevated driving with sweeping views.

Tsavo West's character is defined by its recent volcanic past. The Shetani Lava Flows — black, jagged, barely colonised by vegetation — cut through the park in stark geological contrast (Shetani means 'devil' in Swahili; the flows look recent enough to justify it). Mzima Springs is Tsavo West's centrepiece: a subterranean oasis where an estimated 50 million gallons of crystal-clear water emerge daily from beneath the lava, fed by underground aquifers from the Chyulu Hills. The springs support hippos, Nile crocodiles, and large fish in extraordinary water clarity. A submerged glass observation chamber allows visitors to descend below the water surface and watch hippos moving underwater — one of the most unusual wildlife viewing opportunities in Kenya. The Ngulia Rhino Sanctuary provides protected access to black rhinos — critically endangered, but here reliably encountered.
