In Tanzania, the Great Migration can be experienced throughout the year. From January to March, the herds gather across Ndutu and the southern Serengeti for the wildebeest calving season. Between April and June, they move north through the central Serengeti and Western Corridor. From July to October, they reach the northern Serengeti, where Mara River crossings may occur. During November and December, the herds begin returning south.
In Kenya, the main migration season in the Masai Mara usually runs from July to October. August and September often bring the largest herd concentrations and stronger possibilities of witnessing river crossings. Outside these months, the Masai Mara still offers excellent resident wildlife, but most migrating wildebeest are generally in Tanzania.
Choose Tanzania for a wider range of migration seasons, Kenya for the concentrated July–October period, or combine both countries for a longer Serengeti and Masai Mara journey.
