Great Migration Safari: Northern Serengeti

Safari Overview

Tanzania's national aerial census in 2023 (TAWIRI, co-conducted with Frankfurt Zoological Society and the University of Glasgow) counted 1,366,109 wildebeest in the Greater Serengeti. A 2025 Oxford satellite study suggested the number may be lower, around 800,000; the gap is unresolved and under active scientific review. The commonly cited figure of 1.5 million conflates wildebeest with zebra and Thomson's gazelle. Two million has no primary source. Whatever the exact count, when the bulk of the herd reaches the northern Serengeti from late July onward, the scale is unlike anything else in Africa. The migration runs on rainfall, not calendar. Year-to-year variance in arrival timing can be four to six weeks. In June, herds are in the Western Corridor crossing the Grumeti. The vanguard typically reaches Kogatende from mid-July. August and September are the peak months for Mara crossings. By late October the short rains approach, herds begin moving south, and the window closes. A booking past October 20th carries real risk of missing the crossings entirely. The Mara River at Kogatende has ten to twelve TANAPA-designated crossing points. Crossings 4 and 5 are the most dramatic, with steep banks and deep pools. Crossing 2 is the most photogenic. Crossings 9 through 12 have the fewest vehicles. On a three-to-four night August stay, the probability of seeing at least one major crossing is roughly 80 percent. Four to five nights push the odds meaningfully higher. This itinerary gives you three full days at the river, then drives south through the central Serengeti to Ngorongoro Crater on the return.

Your Itinerary

1. Day1

   Arrive Arusha

   Transfer from Kilimanjaro International Airport to your Arusha hotel, about 45 minutes on a clear day. Dinner and a full briefing: crossing point geography, TANAPA rules at the Mara, what to realistically expect. The drive to the Serengeti begins in the morning.

   Overnight

   Arusha Coffee Lodge or similar

   Dinner
2. Day2

   Arusha to Central Serengeti via Olduvai Gorge

   Arusha to Central Serengeti · 7 to 8 hrs with stops at Olduvai Gorge

   Pickup at 7:00am. The drive to the Serengeti takes about six hours with stops. You climb through the Ngorongoro highlands, pass through the Conservation Area, and stop at Olduvai Gorge before Naabi Hill Gate. In 1959, Mary Leakey found the skull of Paranthropus boisei here, a hominid who walked these plains 1.8 million years ago. The site guide does a 20-minute talk at the excavation. Worth every minute. Arrive in the Seronera area in late afternoon for a first game drive on the central plains.

3. Day3

   Full Day Central Serengeti: Seronera Valley

   Full day in the Seronera Valley, the most consistent big-cat zone in the Serengeti year-round. Leopards rest in the sausage trees above the river. Lions claim the kopjes, granite outcrops 600 million years old. Cheetahs work the short-grass plains to the south. Depending on your travel dates and the current herd position, fringes of the migration may be passing through Seronera en route north. The resident predators are here regardless. Full day in the park, picnic lunch.

4. Day4

   Central Serengeti to Northern Serengeti: Kogatende

   Central Serengeti to Northern Serengeti · Mara · 4 to 5 hrs on the road, run as a game drive

   The drive from Seronera to Kogatende is 160 to 170 km on murram and dirt track. Five to six hours in dry conditions. This is not dead time: you are crossing the full length of the Serengeti through Lobo Hills and kopje country, with wildlife throughout. Arrive at your northern camp in the afternoon. First look at the Mara River before dark. Depending on herd position, you may see animals massing on the south bank. First briefing from your guide on which crossing points are showing activity.

5. Day5

   Northern Serengeti: Mara River Crossings

   Out by 6:00am. Your guide positions the vehicle at the crossing point showing the most activity, based on overnight herd movement and morning field contacts. TANAPA's revised guidelines require vehicles to hold position at designated points, at least 25 metres from the bank, stationary during crossing events. No disembarking. Each numbered crossing point has a designated maximum vehicle count. Herds mass, press to the water's edge, turn back. There is no lead animal and no predictable trigger. Behavioral research identifies it as a collective decision: a small committed group at the water's edge tips the calculation for the herd behind them, or it does not. A crossing can be over in four minutes. The same point may see a second wave within the hour, or nothing for two days. Between events, the northern Serengeti has strong resident game regardless of migration timing: lion, leopard, cheetah, elephant, buffalo.

6. Day6

   Northern Serengeti: Second Full Day at the Mara

   Second full day at the crossing points. Your guide repositions based on overnight herd movement. Crossings 4 and 5 are the most dramatic, with high banks and deep croc pools. Crossing 2 is the most photogenic. Crossings 9 through 12 are the least crowded. Morning light from the Kogatende (south) bank is best before 9:00am, with herds approaching front-lit from the east. Afternoon light favors the Lamai Wedge north of the river, with warm sidelight on animals emerging from the water. Your guide chooses the crossing point based on light and herd position. Picnic lunch at the river.

7. Day7

   Northern Serengeti: Third Full Day at the Mara

   Third full day. Three nights at Kogatende is the minimum for meaningful crossing odds; this is the day the probability calculation is firmly in your favour. By now your guide knows the rhythm: which bank the herd is favouring, which crossing points are showing massing behaviour, where the main croc pods are concentrated. Crocodile density in the Tanzanian Mara stretch is high. No formal site-specific count has been published for the Kogatende reach, but they are visible from the bank at any active crossing point during the season.

8. Day8

   Final Morning at the Mara, then Drive South

   Northern Serengeti · Mara to Central Serengeti · driven south as a full game-drive day

   Final morning at the crossing points from 6:00am. Depart mid-morning and drive south through the park. The route back to Seronera takes five to six hours on the same murram track through the full length of the Serengeti. The Lobo area in the northeast passes through kopje country with consistent lion sightings. Game drives throughout the drive south. Arrive at the central Serengeti lodge late afternoon.

9. Day9

   Serengeti to Ngorongoro Crater Rim

   Central Serengeti to Ngorongoro Crater · 3 to 4 hrs, gravel then tarmac near the rim

   Morning game drive in the Seronera Valley, then depart through Naabi Hill Gate. The drive to the Ngorongoro rim takes about three and a half hours, climbing through montane forest thick with olive trees and giant heather. Arrive for lunch. The crater floor is 600 metres below. On a clear afternoon you can see the animal herds from the lodge terrace. Early dinner. The descent begins at 6:00am.

    Ngorongoro Crater then Depart

    Ngorongoro Crater to Arusha · 3.5 to 4 hrs, mostly tarmac

    Descent at 6:00am before the tourist vehicles arrive. The track drops 600 metres through cloud forest over 30 minutes of switchbacks. On the crater floor: approximately 120 lions, 50 black rhino at the densest population in East Africa, 15,000 wildebeest, 400 hyenas, 9,000 zebra, all inside 260 square kilometres of enclosed caldera they rarely leave. Picnic lunch at Ngoitokitok Springs. Ascend mid-afternoon, drive to Arusha (three hours). Drop-off at your hotel or Kilimanjaro International Airport. Earliest viable international departure is 21:00.

Where Your Money Goes

Migration Calendar: Month by Month

The migration runs on rainfall, not calendar. Year-to-year variance in arrival timing can be four to six weeks. The 2024 season saw the first Mara crossing on June 29th, unusually early. Treat the windows below as central tendencies.

June. The bulk of the herd is in the Western Corridor, approaching or crossing the Grumeti River. Grumeti crossings typically run from late May through early July. The Grumeti is narrower than the Mara (10 to 50 metres), crossing groups are smaller, and vehicle counts are much lower. The crocodile pods here are famously large: wildlife surveys from the 1990s recorded roughly three times the crocodile density of comparable Mara stretches. Worth seeing on its own terms, but it is not the Mara.

July. Transition. The vanguard reaches Kogatende mid-month in a typical year. Visitors arriving in the first half of July are better positioned starting in the Western Corridor and moving north rather than committing to Kogatende from day one. The first crossings of the season tend to be intense per-event (hungry crocodiles, smaller initial crowds) but timing is uncertain.

August. Peak. Herds concentrated in the Kogatende and Lamai Wedge areas. The most active crossing points are 4 and 5 (most dramatic), 2 (most photogenic), 7 and 10 (most consistent). Crossings cluster: multiple events in one morning, then days of massing without a crossing. Vehicle counts at the famous points are at their highest.

September. Comparable to August for crossings, materially fewer vehicles. Herd density at Kogatende slowly declines as a growing fraction has crossed into Kenya or begun the southward turn. Major crossings still occur throughout the month. The best month for the experience-to-crowd ratio. Photography conditions improve: lower sun angle, drier air.

October. Tail end with real risk. Crossings still occur in early to mid October. Nomad Tanzania recorded a Mara crossing on October 16th, 2024. After October 20th, the odds drop sharply in a typical year and short rains can trigger sudden southward movement. An October booking past the 20th is a genuine gamble.

What Happens at a Mara River Crossing

Wildebeest have no permanent dominance hierarchy. Any individual can initiate a crossing, which is why crossings cannot be predicted to the hour.

Behavioral research (Torney, Hopcraft et al., 2018, Philosophical Transactions of the Royal Society B) documents the mechanism: a small committed minority at the water's edge, sometimes fewer than a dozen animals, can tip the collective calculation of a herd of thousands. Once one wildebeest enters the water, the surrounding mass follows. The flip from hesitation to full commitment can happen in under a minute. Herds have also been documented massing on the bank for multiple days before turning back. This is a false start, not a malfunction.

The Mara at Kogatende has ten to twelve designated crossing points. Crossings 4 and 5 are the most dramatic; Crossing 2 is the most photogenic; Crossings 9 through 12 have the fewest vehicles. Guides track herd positions through field contacts each morning.

TANAPA's June 2024 crossing guidelines require vehicles to hold position at designated points, maintain 25 metres from the bank, stay stationary during crossing events, and never allow disembarking. In August 2025, TANAPA issued one-year professional bans to six guides from major operators, including Asilia and Nomad, for allowing guests to leave the vehicle at a crossing. The rules are actively enforced. Foot presence at the bank causes false starts and disrupts the crossing decision. Saleh Safaris follows the rules. Every drive.

Northern Serengeti Camps and How to Get There

The camps within 30 minutes of the Mara crossing points divide by bank.

South bank (Kogatende side): Sayari Camp (Asilia Africa), Olakira Migration Camp (Asilia Africa, mobile June to October), Serengeti Bushtops, Lemala Kuria Hills. Morning light is best from this side: approaching herds are front-lit before 9:00am.

North bank (Lamai Wedge): Lamai Serengeti (Nomad Tanzania), Singita Mara River Tented Camp. Afternoon light is best here, with warm sidelight on animals emerging from the water.

All of these camps are seasonal, typically June through October, and August dates book out months in advance.

Getting there: two options. Driving from Arusha to the central Serengeti takes six to seven hours on paved road. Then Seronera to Kogatende is another 160 to 170 km on murram and dirt track, five to six hours in dry conditions. Night driving inside the park is not allowed. The drive through the Lobo Hills is a game drive throughout. Flying is the faster option: scheduled bush flights run from Arusha to Kogatende Airstrip (GTZ), roughly 1.5 hours with intermediate stops. Flying removes two long transit days and adds one to two crossing sessions on a 10-day itinerary. Ask about fly-in pricing when you enquire.

Practical note: dawn at Kogatende in July through October runs 8 to 15 degrees Celsius. Bring a fleece for early departures.
