While the migration is an ongoing event, September is a particularly exciting month—river crossings are at their peak, and these crossings are the stuff of safari legend. The Mara River, with its steep banks and crocodile-filled waters, becomes a battleground where survival is not guaranteed.
In this guide, we’ll explore why September is the perfect time to witness the Great Migration and why it’s the best month for seeing these breathtaking river crossings.
1. The Peak of the River Crossings
The Mara River crossings are among the most sought-after events of the Great Migration, and September is prime time to catch this dramatic spectacle. By now, the large herds of wildebeest and zebras that have traveled from the southern Serengeti are concentrated around the northern Serengeti and Maasai Mara.
The Mara River acts as both a lifeline and a deadly obstacle. To reach the lush pastures on the other side, the herds must cross the river, where dangers like crocodiles and swift currents await. The crossings are chaotic, with animals jostling for position, jumping from steep riverbanks, and struggling to avoid predators lying in wait.
While smaller crossings may begin as early as July, the larger, more dramatic crossings typically occur in late August through September, making this month the perfect window to witness the action.
Why September?
- The herds are in their largest concentrations, creating dramatic and larger-scale crossings.
- The river levels are ideal—neither too high nor too low, which enhances the action.
- The dry season reduces the available grazing land, forcing more animals to cross the river in search of fresh grass, which increases your chances of witnessing multiple crossings.
2. The Drama and Danger of the Mara River
What makes September’s crossings so special is the sheer danger involved. The Mara River crossings are often called “the greatest show on Earth” because of the life-or-death stakes involved for the wildebeest and zebras.
Here’s why it’s so dramatic:
- Crocodiles: The Mara River is home to massive Nile crocodiles, some of the largest in Africa, who have been waiting for months for this feast. As the wildebeest leap into the water, these ancient predators strike, creating heart-stopping moments of nature’s raw power.
- Swift currents: The river’s currents can be treacherous, especially after rain. Wildebeest calves and smaller animals often struggle to keep up, creating tense moments as they fight to reach the other side.
- Steep riverbanks: The crossings are often made more dangerous by the steep, muddy banks on either side of the river. Animals can slip and fall, leading to heartbreaking moments as some are trampled or swept away.
While these crossings are fraught with danger, they are also a symbol of nature’s resilience. It’s a reminder of the circle of life, as not every animal will make it across, but those that do continue on to greener pastures.
3. Fewer Crowds for a More Intimate Experience
September marks the end of the peak tourist season, which means you’ll experience fewer crowds at the Mara River. From June to August, safari-goers flock to see the migration, but by September, many have left, giving you a more intimate experience.
With fewer tourists, you’ll have better opportunities to:
- Position your vehicle for unobstructed views of the crossings.
- Spend more time at key crossing points without feeling rushed by other vehicles.
- Enjoy the quiet moments of the Serengeti and Maasai Mara, allowing you to truly soak in the beauty of the African wilderness.
The lower number of tourists also means better deals on lodges and safari packages, giving you more flexibility in choosing prime locations along the river.
4. The Changing Landscape: End of the Dry Season
By September, the dry season is reaching its peak. The landscape is dusty and parched, which creates striking contrasts against the lush greenery on the other side of the Mara River. This dramatic change in landscape is part of what drives the herds to cross the river in the first place—fresh grazing lands are scarce, and the rains will soon arrive to revitalize the plains.
This stark, arid environment makes for incredible photography, with animals kicking up dust as they race toward the river, set against the golden hues of the savannah.
For photographers, September is a fantastic month to capture the contrast between the dry, cracked earth and the life-giving water of the Mara River, with the drama of the migration playing out in the foreground.
5. Predator Action: Lions, Crocodiles, and Hyenas
Where there are herds, there are predators. And in September, the concentration of wildebeest and zebras means big predator action.
The river crossings provide ample hunting opportunities for lions, leopards, hyenas, and of course, the massive Nile crocodiles. As the herds gather along the riverbanks, predators stalk the area, waiting for the perfect moment to strike.
- Lions: You’ll often spot lions near the riverbanks, especially early in the morning or late in the afternoon when they are most active. They’re opportunistic hunters, and during September, their presence is strongly felt as they take advantage of the chaotic migration.
- Crocodiles: As mentioned earlier, the Nile crocodiles are the stars of the Mara River crossings. Watching them attack is a reminder of their terrifying power and precision.
- Hyenas: These scavengers follow the migration closely, always ready to clean up after the big predators or to chase down young or injured wildebeest.
For wildlife enthusiasts and photographers, this predator-prey dynamic offers a thrilling spectacle and unforgettable moments that few other places in the world can rival.
6. Best Places to Watch the Crossings
If you’re traveling in September to witness the Mara River crossings, it’s essential to be in the right place at the right time. Here are the top areas to position yourself for the best chance of seeing the migration in action:
- Northern Serengeti: In Tanzania’s Kogatende area, you’ll find fewer tourists but still have excellent access to the river crossings. There are plenty of luxurious camps and lodges in this region that are strategically located for prime migration viewing.
- Maasai Mara National Reserve: In Kenya, the Mara is a hotspot for migration activity in September. Camps located near the Mara Triangle and along the Sand River often offer exclusive access to some of the best crossing points.
Consider staying in mobile camps, which move with the herds, giving you flexibility and better positioning for the crossings.
7. Be Patient: Timing is Everything
One of the most crucial elements of seeing a river crossing is timing. Wildebeest herds can gather at the riverbanks for hours, even days, before making the leap into the water. It takes patience and often a little bit of luck.
Pro Tip: Stay with your guide and keep an eye on the behavior of the herds. Often, a few bold wildebeest will start the crossing, and once they go, the rest will follow in a frenzy. It’s an unpredictable event, but your patience will pay off with some of the most incredible wildlife moments you’ll ever witness.
