Great Migration Route

Great Migration Route: Serengeti to Masai Mara Month-by-Month Guide

The Great Migration Route follows one of the most remarkable wildlife movements on Earth. Each year, vast herds of wildebeest, zebras and gazelles travel through the connected Serengeti–Masai Mara ecosystem, moving between southern Tanzania and southwestern Kenya in search of fresh grazing and water. Related planning topics include wildebeest migration route and wildebeest migration path.

The route is often described as a giant circular journey, but in reality it is more complex. The migration does not move as one single herd along a fixed track. Instead, different groups spread across large sections of the ecosystem, sometimes separated by many kilometres. Rainfall, grass quality, water availability and local weather determine how quickly the herds move and where they concentrate. For this reason, the Great Migration route should be understood as a broad seasonal pattern rather than a precise road map.

A simplified route generally follows:

Southern Serengeti and Ndutu
Central Serengeti
Western Corridor
Grumeti region
Northern Serengeti
Mara River
Masai Mara
Northern Serengeti return
Eastern and central Serengeti
Southern Serengeti and Ndutu again

This page explains the migration route in detail, including the main geographic zones, typical month-by-month movement, important river crossings and the best places to plan a safari at different stages of the cycle.

How the Great Migration Route Works

The Great Migration is driven mainly by the search for:

Fresh grazing
Water
Rain-fed grass
Suitable calving conditions

Wildebeest do not migrate according to a calendar. They respond to changing environmental conditions, which means the exact migration route can vary from year to year. For example:

Early rains can speed up movement.
Delayed rains can keep herds in one region longer.
Local storms can pull some groups away from the main concentrations.
Water availability can influence which river systems the animals approach.
Different herds can move along different paths at the same time.

The route therefore needs to be interpreted flexibly.

The Great Migration Is Not One Single Herd

One of the biggest misconceptions is that all the wildebeest travel together in one enormous mass. In reality, the migration can spread across a vast area, and visitors may encounter:

One huge concentration
Several large herds
Long columns of moving animals
Smaller scattered groups
Mixed zebra and wildebeest groups
Herds moving in different directions

This is important when planning a safari. A region may still offer excellent migration viewing even if the largest concentration is elsewhere.

Stage 1: Southern Serengeti and Ndutu

The southern Serengeti and Ndutu region are among the most important areas in the annual migration cycle. This phase is generally associated with December to March. The plains become especially important because they provide short, nutrient-rich grass after seasonal rains, and large numbers of wildebeest gather here.

Wildebeest Calving Route

The southern plains are famous for the wildebeest calving season. The main calving period usually peaks around January and February, though exact timing varies. During this time, the landscape can hold immense concentrations of pregnant females and newborn calves.

The attraction for wildlife enthusiasts is not only the number of calves, because predator activity can be exceptional. Visitors may see:

Lions stalking herds
Cheetahs targeting young animals
Hyenas hunting calves
Jackals scavenging
Vultures gathering around kills

For travellers visiting in the first months of the year, the Great Migration route is overwhelmingly Tanzania-focused.

Why the Migration Begins in Southern Serengeti

The southern plains receive seasonal rainfall that creates short, highly nutritious grass, which is particularly suitable for wildebeest mothers and calves. The ecosystem also provides broad open landscapes, allowing migrating herds to spread over enormous areas. Once grazing deteriorates and rainfall shifts, the herds begin moving again.

Stage 2: Ndutu to Central Serengeti

As the southern plains begin drying, many herds start moving northward. This phase often occurs approximately March to April. The movement is gradual: some herds may remain farther south, while others begin entering central Serengeti, so the migration can appear widely dispersed.

Central Serengeti Migration Route

Central Serengeti acts as a major transition zone. The Seronera region and surrounding plains support abundant resident wildlife throughout the year, and when migrating herds pass through, the area can become extremely active.

Travellers may see:

Long wildebeest columns
Mixed zebra herds
Lions hunting among migrants
Leopards near riverine areas
Cheetahs using open plains

This part of the route is less famous than river crossings but can provide exceptional general safari experiences.

Stage 3: Western Corridor

From central Serengeti, many herds move toward the western corridor. This phase is commonly associated with May to June, when large numbers of wildebeest may move toward the western parts of the Serengeti. The landscape here differs from the open southern plains and includes:

Woodland
River systems
Grassland
Western migration corridors

This is one of the most important transitional sections of the Great Migration route.

Grumeti Migration Route

The Grumeti region is strongly associated with the westward and northward movement of the herds. The Grumeti River becomes an important natural obstacle, and crossings can occur here, although they differ from the better-known Mara River crossings. The Grumeti region can offer excellent migration viewing before the herds reach northern Serengeti.

Grumeti River Crossings

The Grumeti River is home to large crocodiles, and wildebeest may cross the river during their movement north. However, these crossings are generally less concentrated and less predictable than some Mara River crossing events. The Grumeti phase is still extremely important because it marks the transition from western Serengeti toward the northern migration zone.

Stage 4: Western Serengeti to Northern Serengeti

As the dry season develops, herds continue north. This movement often occurs around June to July. Some animals move faster than others, and by late June or July, significant numbers may reach northern Serengeti. The northern region becomes increasingly important because it contains the Mara River and extensive dry-season grazing.

Northern Serengeti Migration Route

Northern Serengeti is one of the most important migration regions, and it links directly with Kenya's Masai Mara. During July, August, September and parts of October, large concentrations of wildebeest may be found here.

The landscape includes:

Open plains
Rolling hills
River systems
Woodland
Mara River crossing points

Northern Serengeti is especially important for travellers wanting to experience the migration before or after the herds enter Kenya.

Stage 5: The Mara River

The Mara River is perhaps the most famous section of the Great Migration route. It flows through both Tanzania and Kenya, which means Mara River crossings can occur on either side of the international border. The river forms a major obstacle for migrating animals.

Possible challenges include:

Steep banks
Deep channels
Strong currents
Crocodiles
Panic within dense herds
Confusion over where to cross

Why Wildebeest Cross the Mara River

Wildebeest cross the river because the broader migration continues in search of fresh grazing. They are not crossing specifically to reach Kenya, and they may cross:

Northward
Southward
Back and forth

The direction depends on available grazing and local conditions. This is why visitors can sometimes witness multiple crossings during one season.

Mara River Crossing Route

There is no single permanent crossing point. Different crossing sites become active depending on where the herds approach the river.

Some crossings involve:

Small groups
Several hundred animals
Thousands of wildebeest
Large numbers of zebras

A crossing can begin with little warning.

Stage 6: Masai Mara

Once the herds enter Kenya, they spread across the Masai Mara ecosystem. This phase is generally associated with July to October, although exact arrival and departure dates change annually.

The animals may spread through:

Masai Mara National Reserve
Mara Triangle
Central Mara plains
Talek region
Riverine areas
Surrounding conservancies

The distribution of the herds changes continuously.

Masai Mara Migration Route

The Masai Mara does not have one simple migration corridor. Wildebeest may move between:

Southern Mara
Mara River areas
Central plains
Western Mara
Northern sections
Border areas near Tanzania

Local rainfall can cause herds to shift quickly. This is why guides often rely on recent wildlife reports rather than predetermined daily routes.

Why the Masai Mara Is Important

The Masai Mara offers:

Extensive dry-season grazing
Reliable water sources
Open plains
Strong predator populations
Access to the Mara River

The area can hold enormous numbers of animals during the northern phase of the migration.

Stage 7: Return from Masai Mara

The herds do not remain in Kenya permanently. As conditions change, they gradually begin moving south again, often around October to November, although some herds may remain longer depending on rainfall. The southward return is less famous than the northward river-crossing phase, but it is equally important to the migration cycle.

Return Route into Northern Serengeti

As fresh grazing develops farther south, many herds move back into northern Serengeti. Some may cross the Mara River again, which can produce additional river-crossing opportunities. The animals then begin spreading through eastern and central parts of the Serengeti.

Stage 8: Eastern Serengeti and Central Serengeti

During approximately October to December, many herds move southward through the Serengeti. Some may travel through eastern areas, while others remain more central. The movement is usually less concentrated than peak northern migration, and rainfall plays an important role, since short rains can encourage faster southward movement.

Stage 9: Return to Southern Serengeti

By late in the year, many herds return toward southern Serengeti and Ndutu. This completes the broad annual cycle. The animals prepare for another calving season, and the cycle then begins again.

Great Migration Route Month by Month

January

Main migration area: Southern Serengeti and Ndutu.

Typical conditions:

Large wildebeest concentrations
Pregnant females
Early calving
Excellent predator activity

Best for:

Calving safari
Predator photography
Southern Serengeti safari

February

Main migration area: Ndutu and southern Serengeti. This is one of the strongest calving months.

Possible highlights:

Thousands of calves
Lion activity
Cheetah hunts
Hyena predation
Vast short-grass plains

March

Main migration area: Southern to central Serengeti. Herds may begin spreading northward, and some calving activity can continue. Rainfall can still be significant.

April

Main migration area: Central Serengeti. Many herds begin moving toward central and western regions, and the migration can become more dispersed.

April can offer:

Fewer safari vehicles
Green landscapes
Predator sightings
Dramatic skies

May

Main migration area: Central and western Serengeti. The herds increasingly move west and large columns may appear, which can make this one of the most dramatic periods for seeing mass movement rather than river crossings.

June

Main migration area: Western corridor and northward routes. The herds may encounter the Grumeti region, and movement toward northern Serengeti accelerates.

July

Main migration area: Northern Serengeti and potentially Masai Mara. This is a major transition month.

Possible highlights include:

Northern movement
Mara River approaches
Early crossings
Large concentrations in northern Serengeti

August

Main migration area: Northern Serengeti and Masai Mara. This is one of the classic northern migration months.

Possible highlights:

Mara River crossings
Large Masai Mara herds
Strong predator activity
Excellent dry-season game viewing

September

Main migration area: Masai Mara and northern Serengeti. Large herds can remain in both regions and crossings may continue, making this one of the best periods for a Kenya–Tanzania combination.

October

Main migration area: Masai Mara, northern Serengeti and southward movement. Herds may begin moving south, and rainfall patterns determine how quickly this occurs.

November

Main migration area: Central and eastern Serengeti. Short rains may pull the herds south, so most migration-focused travellers should begin shifting attention back toward Tanzania.

December

Main migration area: Southern migration route. The herds increasingly return toward southern Serengeti and Ndutu, and the next calving phase approaches.

This table is a planning guide rather than a fixed wildlife timetable.

Great Migration Route in Kenya

Kenya hosts only part of the annual migration route, but it is one of the most dramatic phases. The Kenyan section is primarily concentrated in:

Masai Mara National Reserve
Mara Triangle
Mara River ecosystem
Nearby conservancies

The main migration period in Kenya is generally July to October. This phase is especially important for:

Mara River crossings
Large wildebeest concentrations
Predator activity
Photography

Great Migration Route in Tanzania

Tanzania contains most of the annual migration route. The herds may travel through:

Ndutu
Southern Serengeti
Central Serengeti
Western Corridor
Grumeti
Northern Serengeti

For this reason, travellers can experience some part of the migration in Tanzania during much of the year.

Great Migration Route and River Crossings

The migration encounters several river systems. The most important are the Grumeti River, which is associated mainly with western migration, and the Mara River, which is associated with northern Serengeti and Masai Mara. The Mara River produces the most famous crossing scenes.

Mara River vs Grumeti River

Feature	Mara River	Grumeti River
Location	Northern Serengeti & Masai Mara	Western Serengeti
Main Period	Jul–Oct	May–Jul
Crossing Scale	Can be enormous	Usually more dispersed
Crocodiles	Yes	Yes
Fame	Very high	High
Best Safari Region	Northern Serengeti / Mara	Western Serengeti

Both are important parts of the migration cycle.

Does the Great Migration Always Follow the Same Route?

No. The broad cycle is consistent, but the exact route changes.

Several factors can cause variation:

Rainfall
Drought
Local storms
Grass quality
Water availability
Fire
Herd behaviour

This is why migration maps should be viewed as general planning tools.

Can Wildebeest Move Backward?

Yes. Herds can move in unexpected directions. For example, wildebeest may cross the Mara River and later cross back again, and they may also shift east or west according to grazing conditions. The migration is dynamic rather than linear.

Why Migration Maps Can Be Misleading

A map usually shows arrows pointing around the ecosystem, which is useful for understanding the broad cycle. However, actual migration behaviour is more complicated. A migration map cannot show:

Every herd
Every temporary movement
Rain-driven detours
Local grazing changes
Multiple crossing points
Sudden directional shifts

Maps should therefore be combined with current field information when planning a safari.

Best Safari Areas Along the Great Migration Route

Southern Serengeti and Ndutu

Best for:

Calving
Cheetahs
Lions
Hyenas
Newborn wildebeest

Central Serengeti

Best for:

Year-round predators
Transitional migration movement
Leopard viewing

Western Serengeti

Best for:

Grumeti region
Westward migration
Fewer crowds in some areas

Northern Serengeti

Best for:

Mara River crossings
Large herds
Northern migration

Masai Mara

Best for:

Kenya migration
River crossings
High predator density
Classic dry-season wildlife viewing

Best Route for a July Safari

For July, consider Northern Serengeti and the Masai Mara. A combined itinerary can provide excellent flexibility because herd locations may vary around the border ecosystem.

Best Route for an August Safari

August is ideal for:

Masai Mara
Northern Serengeti
Mara River

A migration-focused itinerary should spend substantial time in these areas.

Best Route for a September Safari

September can be particularly strong for a combination of the Masai Mara and Northern Serengeti. This provides wider access to changing herd locations.

Best Route for an October Safari

October can still include the Masai Mara and Northern Serengeti, but safari planners should monitor the developing southward movement.

Best Route for a February Safari

February should focus on Ndutu and the Southern Serengeti. This is the key calving phase.

Best Route for a May Safari

May is generally better suited to Central Serengeti and Western Serengeti. This is the period of long-distance northward movement.

How to Plan a Safari Around the Great Migration Route

The best planning approach is to work through five steps.

Step 1: Start With Your Month

Your travel month should determine the region.

Step 2: Identify Your Priority

Do you want:

Calving?
River crossings?
Large herds?
Predators?
Photography?
Fewer crowds?

Step 3: Choose the Correct Region

Do not force the migration into a destination that is unlikely to hold major herds during your travel period.

Step 4: Stay Long Enough

Migration-focused visitors should normally spend several nights in the key region.

Step 5: Remain Flexible

Wildlife does not follow fixed schedules.

How Many Nights Should You Spend in a Migration Area?

A practical guideline:

Safari Priority	Recommended Stay
General Migration Viewing	3 nights
River Crossing Focus	4–5 nights
Photography	5–7 nights
Kenya–Tanzania Migration	8–12 total days
Calving Safari	3–5 nights

More time increases flexibility.

Great Migration Route for Photographers

Photographers should avoid moving hotels too often and instead spend more nights in one strategic area. A photography itinerary should prioritize:

Full-day game drives
Private vehicle
Early starts
Flexible meal times
Good camp location
Time to wait for behaviour

Great Migration Route for Families

Families should choose routes with fewer long transfers. A practical family itinerary might focus on:

One migration region
Private vehicle
Family-friendly lodge
Flexible game-drive schedule

For example, during August, a family may choose four nights in Masai Mara rather than trying to combine too many parks.

Great Migration Route for Honeymooners

Honeymooners can combine the migration with luxury camps and beach extensions. Popular routes include:

Masai Mara + Diani
Masai Mara + Serengeti + Zanzibar
Northern Serengeti + Zanzibar

The best route depends on travel month.

Great Migration Route and Safari Cost

Safari cost varies according to where the migration is located. Key cost factors include:

Camp season
National park fees
Conservancy fees
Domestic flights
Number of nights
Private vehicle
Cross-border logistics
Accommodation level

Peak northern migration months can be among the most expensive periods.

Great Migration Route and Mobile Camps

Mobile camps are particularly useful along the migration route, and some seasonal camps relocate during the year to remain close to expected herd movements. Advantages include:

Better seasonal positioning
Strong wilderness atmosphere
Reduced transfer time to migration zones

Travellers should check exactly where a mobile camp will be located during their travel dates.

Great Migration Route and Conservancies

In Kenya, private conservancies near the Masai Mara can complement migration viewing. Benefits can include:

Fewer vehicles
Night game drives
Bush walks
Off-road viewing where permitted
Exclusive wildlife areas

However, if your primary objective is Mara River crossing activity, make sure your itinerary also provides adequate access to the relevant reserve areas.

Great Migration Route and Balloon Safaris

Balloon safaris are available in several migration regions. They provide:

Sunrise views
Aerial landscapes
Large-scale perspective

However, balloon routes depend on wind direction, and a balloon safari cannot guarantee views of migration herds or river crossings.

Common Mistakes When Following the Great Migration Route

Mistake 1: Treating the Route as Fixed

The migration changes every year.

Mistake 2: Assuming July Always Means Masai Mara

Some herds may still be in northern Serengeti.

Mistake 3: Booking Only One Night Near the Migration

This provides very little flexibility.

Mistake 4: Choosing a Camp Without Checking Seasonal Location

Camp names alone do not guarantee good migration access.

Mistake 5: Expecting a River Crossing on Schedule

Crossings cannot be guaranteed.

Mistake 6: Moving Too Fast Between Regions

Too many transfers can reduce wildlife-viewing time.

Frequently Asked Questions

What is the Great Migration route?

It is the broad annual movement of wildebeest, zebras and gazelles through southern, central, western and northern Serengeti and into the Masai Mara before returning south.

Where does the Great Migration start?

The cycle does not have a true beginning, but many guides describe the southern Serengeti and Ndutu calving phase as the start of the annual cycle.

Does the migration go from Tanzania to Kenya?

Yes, during the northern phase many herds move from northern Serengeti into the Masai Mara.

Does the migration return to Tanzania?

Yes. The herds later move south through Serengeti toward the southern plains.

When is the migration in Masai Mara?

Generally July to October.

When is the migration in northern Serengeti?

Generally July to October, though timing varies.

When is the calving season?

Usually around January to March, with February often a peak month.

When is the migration near Grumeti?

Commonly around May to July.

Can you see Mara River crossings in Tanzania?

Yes. The Mara River flows through northern Serengeti as well as Kenya.

Does every wildebeest cross into Kenya?

No. Different herds can remain in Tanzania or move along different routes.

Is the route the same every year?

No. Rainfall and grazing conditions cause annual variation.
