When to go for the Great Migration River Crossings

Best Time to see the River Crossings Great Migration

August and September are the peak months and considered the best and most reliable time to witness the dramatic Mara River crossings. At this time of year, the Mara River crossings are at their busiest, and the herds gather in the Northern Serengeti near Kogatende and Lamai before crossing into Masai Mara.

By mid-July, the great migration reaches one of its most iconic and perilous stages: the Mara River crossing. Herds congregate at the riverbank in the Northern Serengeti and the Mara River corridor, spending hours or even days in hesitation due to the danger lurking in the murky crocodile-infested waters until a single, daring “leader” decides to take the plunge.

Early to mid-August frequently delivers the highest chances of witnessing large-scale, multi-species crossing events. Columns arrive after the long trek from the southern Serengeti’s calving grounds, causing a surge in pressure to cross, leading to several river-crossing attempts and successful crossings.

Although often overshadowed by the more famous Mara River crossings, the crocodile-infested Grumeti River is one of the first obstacles wildebeest herds encounter on their journey with crossings typically occurring between June and July.

The wildebeest river crossings often coincide with the peak safari season from July through August and early September when the herds head north crossing the Mara River, and again in late October and early November as the herds return south to Serengeti and Ndutu plains.

While the movement of the Great Migration is a year-round spectacle, the best time to see the river crossings is during the dry season, from late June to early October. These months are the peak of the migration season, drawing wildlife enthusiasts from around the world to witness this dramatic spectacle.

The river crossings are highly sought-after. We recommend planning ahead in order not to miss out on prime viewing spots during the peak seasons. You could spend at least three to four days at the crossing points, making it more likely to witness a wildebeest river crossing as they are unpredictable.

If you’re considering to travel in the peak seasons, you can book at least 8-12 months in advance as these months are extremely popular and availability at lodges and camps fills up fast.

For those considering witnessing the wildebeest calving in Southern Serengeti (January to March), booking a few months ahead is advisable. However, flexibility can help secure prime viewing spots during this quieter period.
