Kenya and Tanzania safaris
Kenya and Tanzania share the wildebeest migration. From about July the herds are often on the Mara side. Around February the calving is on the southern Serengeti. A crossing of the Mara River is never a promise for a given morning.
A combined trip is usually a light aircraft between the two, then an optional beach on the Kenyan coast or on Zanzibar. The office will say which parks the quote actually includes. You do not have to do both countries.
