The Mara River runs through the heart of the reserve and is the reason the plains stay alive. It rises in the Mau Escarpment forests to the north and flows south-west through the Maasai Mara into Tanzania, where it carries on to Lake Victoria. For much of the year it is a slow brown river with sandy bends, fig trees and long hippo pools where dozens of animals pile up in the shallows, grunting and yawning. Giant Nile crocodiles, some of them several metres long, lie motionless on the banks waiting for the herds. In the migration season the river becomes the stage for one of the planet’s most famous wildlife dramas, when wildebeest and zebra cross at the steep banks known as the crossing points, and the same stretches are good for elephants coming to drink and for waterbirds, monitor lizards and the occasional leopard in the riverine forest. Even in the quiet months a morning at the river is among the most rewarding drives in the Mara.
You do not need a special ticket to see the river, because it is part of your normal game-drive day, but you do need a guide who knows the access tracks and the best viewpoints. Visiting hours are the same as for the rest of the reserve, with gates generally open from dawn to dusk, and drives are usually done in a morning or afternoon block.
The Mara Triangle on the west bank has a network of tracks to well-known hippo pools and viewing points, while the Narok County side has its own river access, including the stretch near the Mara Serena area and the crossing points used in the migration. Several lodges and camps sit above the river, so you can watch hippos from your own deck at night.
Safety and etiquette
Never get out of the vehicle near the river unless your guide says it is safe and a ranger is present, because crocodiles and hippos are dangerous and move faster than you expect. Keep noise down, avoid driving close to the bank when herds are gathering and resist the urge to push closer for a better photograph.
Hippos leave the water at dusk to graze, so keep clear of paths near the river after dark. If a crossing is under way, your guide may park a respectful distance away and let animals decide the moment.
Plan the visit around the light and the season. Early morning is cooler and animals are more active, while midday sun can make the river harsh for photography. From July to October the river attracts the largest crowds, so arrive early and be prepared to wait, and outside the migration months you will often have the banks largely to yourself. Bring binoculars, a long lens if you have one and a hat, and ask your driver to explain the animals you see; crocodile and hippo behaviour is fascinating when you know what to look for.
Photography and wildlife behaviour
Crocodiles bask with their mouths open to regulate their temperature, which is normal rather than a sign of aggression, and hippos are territorial, with dominant bulls defending stretches of river. Elephants often cross shallow sections in family groups, and the pools below the banks attract fish eagles and herons.
If you want to learn more, ask your guide to explain how the river changes with the seasons, how floods shape the sandbars and how the crossing points have been used for generations. A pair of binoculars and a patient attitude will repay you with detail that photographs alone cannot capture.

Good questions
Can I get out of the vehicle at the river?+
Only where your guide says it is safe, usually at designated viewpoints with a ranger. Crocodiles and hippos are dangerous.
Are there crocodiles all year?+
Yes. Nile crocodiles live in the river all year and gather at crossing points during the migration.
Where do hippos sleep?+
Hippos spend the day in the water and leave to graze on land at night, so lodge decks above the river are good for evening viewing.
Do I need a separate ticket for the river?+
No. The river is inside the reserve and is part of your normal reserve entry and game drives.
What is the best time of day?+
Early morning, when animals are active and the light is soft. Late afternoon is also good.
