It’s the question I’m asked more than any other. Kenya and Tanzania share a border, a migration and most of the same animals — so the honest truth is that you can’t make a bad choice. But they do feel different, and here’s how I’d decide.
Choose Kenya if…
You want variety and value, and the conservancy experience. Kenya’s private conservancies — community land bordering the parks — let you drive off-road, walk and do night drives, with far fewer vehicles. It’s also easier to combine wildly different landscapes (the Mara, Amboseli’s elephants, Samburu’s deserts) in one trip, and the internal flights are short and cheap.
Choose Tanzania if…
You want sheer scale and the classic postcard. The Serengeti is vast in a way the Mara isn’t, the Ngorongoro Crater has no equal, and adding Zanzibar’s beaches is effortless. Tanzania generally costs a little more, and its parks can be busier in the core season, but the grandeur is unmatched.
On the migration
Both countries get it. The herds spend the middle of the year (roughly July–October) in the Mara and the northern Serengeti — the river crossings happen on the border they share. The calving season (January–February) belongs to Tanzania’s southern Serengeti.
My honest take
For a first safari, I lean Kenya — the conservancies make for a more intimate, flexible trip at a friendlier price. For a second safari, or a once-in-a-lifetime splurge, Tanzania’s scale is hard to argue with. And if you genuinely can’t decide? Do both — they were made to be combined.
