Track the Great Migration month by month in 2025. Where herds are located each month, best viewing spots, and when to see river crossings.
The Great Migration never stops—two million wildebeest, zebra, and gazelle move continuously through the Serengeti-Mara ecosystem in an endless search for fresh grazing and water. Understanding where they'll be each month transforms your planning from guesswork to precision.
The migration follows a roughly clockwise pattern driven by rainfall and grass growth:
Herds concentrate on the short-grass plains around Ndutu and Lake Masek. January marks the beginning of calving season—thousands of wildebeest births begin occurring daily.
Ndutu Safari Lodge, Lake Masek Tented Camp, mobile camps in the area. Book 4-6 months ahead.
February represents calving season's peak—up to 8,000 wildebeest born daily during the most intense period. The concentration of vulnerable young attracts extraordinary predator activity.
Stay in Ndutu area; game drives focus on the plains rather than woodland. Early morning offers best action as predators hunt.
February calving rivals August river crossings for drama but with far fewer vehicles. For wildlife action without crowds, calving season often exceeds expectations. Book specific lodges—not all Serengeti locations access the calving areas easily.
As southern grasses deplete, herds begin drifting northwest. March is transitional—you might find herds in southern plains, central woodlands, or moving between areas.
March requires flexibility—herds move unpredictably. Stay at central locations (Seronera area) for best access to wherever animals concentrate.
Heavy rains trigger continued northwest movement. Herds spread through central Serengeti and begin entering the Western Corridor. Mating season occurs during this period.
Rainy conditions can challenge game viewing. Grass grows tall, roads may be difficult. However, dramatic landscapes and mating behavior reward patient visitors.
Herds mass in the Western Corridor around the Grumeti River. June represents excellent value—migration present, dry season beginning, prices below peak. The first river crossings occur (Grumeti River).
June offers migration viewing without August prices or crowds. Stay in Western Corridor lodges for proximity to action.
Herds push north toward the Mara River. First major Mara River crossings begin—the iconic imagery that defines migration in most travelers' minds.
Northern Serengeti camps fill 6-12 months ahead for July. Mara River-specific locations command premiums. Book immediately when dates are confirmed.
August delivers safari's most famous spectacle—massive herds crossing the crocodile-infested Mara River. Drama peaks as thousands attempt the treacherous crossing daily during peak periods.
August brings both peak wildlife and peak crowds. Crossings attract many vehicles; patience required at popular crossing points. Worth it for the spectacle; manage expectations about exclusivity.
Crossings are unpredictable—herds might wait hours or days before crossing. Stay at camps near multiple crossing points, dedicate full days to waiting, and trust experienced guides who know herd behavior patterns.
September continues crossing drama with slightly reduced crowds as European school holidays end. Herds move between Kenya and Tanzania, sometimes crossing back multiple times.
Following the short rains, herds begin returning south. The journey spreads across eastern Serengeti as animals follow fresh grass growth.
Herds return to the southern plains to complete the cycle. By late December, concentration builds in the Ndutu region, preparing for January-February calving.
For river crossings: July-September (peak August). For calving: January-February. For value: June or November. The "best" depends on whether you prioritize dramatic crossings, calving action, or budget optimization. See our timing guide.
Migration herds spend July-October in both Serengeti (Tanzania) and Masai Mara (Kenya). You can see crossings in either country during those months. However, calving season (January-February) occurs exclusively in Tanzania's southern Serengeti.
Migration timing varies 2-4 weeks based on rainfall. Good operators adjust itineraries based on current herd locations. Book with flexible operators, consider longer trips, and trust guide knowledge over rigid schedules. Sometimes herds surprise everyone.
No. Crossings depend on herd behavior, water levels, and predator presence. Herds might cross multiple times daily or wait days between crossings. Full-day positioning at crossing points maximizes chances, but nothing is guaranteed. Plan multiple days in crossing areas.
Combine both in 7-10 day itineraries. Ngorongoro is en route between Arusha and Serengeti. Visit crater for Big Five, then proceed to whichever Serengeti region hosts migration during your dates. We create combined itineraries regularly.
Share your dates, and we'll show exactly where migration herds should be and design an itinerary placing you in the right location at the right time.
