Wildlife and parks
Tanzania offers scale — the Serengeti and Ngorongoro are immense. Kenya offers density and variety within shorter distances.
Migration timing
Tanzania holds the herds for most of the year; Kenya's Mara is the classic crossing destination from roughly July to October.
Practicalities
Kenya generally involves shorter transfers. Tanzania combines easily with Zanzibar and Kilimanjaro.
Or do both
A combined Serengeti and Maasai Mara journey is one of the most rewarding safaris in Africa.
