Within the boundaries of the Serengeti, you’ll hear thousands of animals: Hyenas cackle as elephants trample well-worn safari roads and hippos splash in watering holes. And at any given time, more than 2,000 lions are poised to pounce on unsuspecting prey, preparing to chase their unlucky target through the seemingly endless waves of golden grass. The scenery rustles with the swift steps of loping giraffes, and tree branches shake with every monkey’s movement. But the most magical site you’ll behold is The Great Migration, during which White’s paradise is drowned by a sea of animals as more than one million wildebeest, zebras and gazelles traverse the Serengeti in search of greener pastures.
Best Months to Visit
The best times to visit Serengeti National Park are from January to February or from June through September, although you should plan your trip around the movement of The Great Migration. For example, winter is the best time to see the herd in Southern Serengeti, while the Western Corridor and Northern Serengeti are the best places to spend the summer and autumn months. Most safari operators will have a good idea of where the animals are headed and when, and most will adjust their itineraries based on the herd’s movement. Temperatures remain relatively constant with daytime highs resting in the 80s. You’ll find cooler weather in the Ngorongoro Conservation Area due to its higher elevation. April and May see the most rainfall, and many lodges and camps close for this slower season.
