Northern Circuit

The Northern Circuit is the backbone of Tanzanian safari. From Arusha, a city of 600,000 people nestled at the foot of Mount Meru (4,566 m), our 4x4s head west and connect four protected areas that complement each other: Tarangire, Lake Manyara, Ngorongoro, and the Serengeti. Together, they form an ecological corridor that the Maasai have traversed for centuries with their herds, across the highlands of the Eastern Rift.

Geography dictates everything. The Rift traces here a succession of escarpments and basins: the Manyara cliff drops 600 meters onto the alkaline plain of the lake, the Ngorongoro crater (collapsed caldera of 260 km²) sinks to 1,800 m elevation at its floor, and further west the Serengeti plains unfold 14,750 km² of savanna on volcanic substrate, legacy of eruptions from Ol Doinyo Lengai (still active, last major eruption 2007-2008). This diversity of altitudes, from 950 m at Tarangire to over 2,300 m on the crater's edge, explains why wildlife constantly moves between these zones.

Tarangire, the first park encountered after 2.5 hours of rough tracks from Arusha, is known for its baobab density and elephant concentrations during the dry season (July to October), when the Tarangire River becomes the only permanent water source for 100 km around. Lake Manyara, smaller, offers a swift transition between groundwater forest and acacia savanna, with populations of olive baboons and, some years, tree-climbing lions. Ngorongoro is a conservation area, not a national park: the Maasai still live here with their cattle, around 90,000 people in the NCA, making it one of Tanzania's rare models of coexistence between wildlife and pastoralism.

The Serengeti remains the circuit's pivot. The word comes from Maa siringet, meaning "the land of no boundaries." The great migration follows a tight calendar that our team plans according to your dates: southern zone (Ndutu, Naabi) between January and March for wildebeest calving, roughly 8,000 per day at peak; central corridor (Seronera) in April-May; west (Grumeti corridor) in June; north (Kogatende, Mara crossing) between July and October. Choosing the wrong zone at the wrong season means missing the spectacle. We therefore work with mobile camps that follow the herds rather than fixed lodges for travelers who truly want to see the migration.

On the cultural side, the Northern Circuit is more than a succession of parks. The village of Mto wa Mbu, at the entrance to Manyara, brings together a hundred Tanzanian ethnicities and offers walks through banana plantations and among Makonde artisans. The Hadzabe, one of East Africa's last hunter-gatherer peoples, live around Lake Eyasi about 1.5 hours from Ngorongoro: we organize short morning visits with an interpreter fluent in their click language. For dining, expect nyama choma (grilled meat), Arusha pilau fragrant with clove, and mandazi at breakfast.

Nights are spent between 1,500 and 2,300 m altitude. On the Ngorongoro rim, the thermometer drops to 8-10 °C before dawn, fleece and hat recommended. On the Serengeti plains, cool mornings quickly give way to 28-30 °C during the day. This thermal range surprises travelers who imagine Africa uniformly hot.

Must-see

Descent into Ngorongoro Crater. A half-day game drive at 1,800 m on the caldera floor, where black rhinos, dark-maned lions, and pink flamingos on Lake Magadi live permanently. The descent track leaves from Seneto Pass and drops 600 m in switchbacks.

Mobile camp on the Mara, August-September. Bivouac at Kogatende, in the Serengeti's north, to observe wildebeest crossings over the Mara River. Passages concentrate at specific fords that our guides pinpoint by radio that morning.

Tarangire baobabs in the dry season. Between July and October, elephant herds gather by 200 or 300 individuals along the river. The baobabs, some millennia old, serve as a pantry: their bark bears tusk marks.

Morning with the Hadzabe of Lake Eyasi. Departure before dawn to follow a bow hunt with a small Hadzabe group. No staging: you walk 2 to 3 hours through the bush, you return with or without game. One of East Africa's rare active hunter-gatherer cultures.

Hot air balloon flight over the Serengeti. Takeoff at sunrise from Seronera or Ndutu depending on the season, one silent hour of low-altitude flight above the herds, followed by breakfast served in the savanna. Book 3 to 4 months in advance during high season.

When to go

Two windows stand out. The dry season, from late June to October, offers the best game-drive conditions: short grass, wildlife concentrated around water sources, clear skies, temperatures of 12 °C at night to 26-28 °C during the day. This is also the period of Mara crossings in the northern Serengeti. Drawback: it's high season, lodges fill 6 to 8 months ahead and prices rise 30 to 40%. The short dry season of January-February is our preferred period for the Serengeti's southern zone: massive wildebeest calving at Ndutu, golden morning light, more moderate crowds.

Two periods to avoid or approach cautiously. The long rains, mid-March to mid-May, turn some tracks into mudfields, notably in central and western Serengeti; some mobile camps close. You can travel in April if you accept days with 2 to 3-hour downpours and seek solitude (parks nearly empty, lower rates). The short rains from November to mid-December are briefer, often late afternoon, and don't prevent safaris; this is an interesting window. On the Ngorongoro highlands, bring a fleece year-round: at 2,300 m, mornings regularly drop below 10 °C, even in warm season.

Practical tips

Allow 6 to 8 days minimum to chain Tarangire, Ngorongoro, and Serengeti without rushing. Below that, you cut the Serengeti, which is a shame given the distance covered (Arusha-Seronera is 8 hours of rough track). A 9 to 10-day plan lets you add Lake Manyara, a morning with the Hadzabe, and take time to observe rather than check boxes. Logistics entry point: Kilimanjaro International Airport (JRO), 45 min from Arusha, served direct from Amsterdam, Doha, Addis Ababa. Transfers between parks are by private 4x4 with English-speaking or Francophone driver-guide as available; domestic flights (Coastal Aviation, Auric Air) usefully shorten the return from the Serengeti, 1.5 hours versus 8 hours of track.

The most classic combination remains Northern Circuit then Zanzibar and the Swahili coast: 1 hour 15 minutes flying to shift from safari to beach, a balance appreciated by families and couples. For travelers wanting safari and nothing but safari, we propose extending into the Wild South (Ruaha, Nyerere) which offers a very different face, more solitary and less traveled. Walkers can combine with Kilimanjaro or Meru upstream of the circuit. Comfort levels are high: the North's lodges and mobile camps rank among East Africa's finest, with a genuine range of budgets, from €250 to €1,500 per person per night in full board. This is a region suitable for families with children from 6-7 years old, for contemplatives and photographers; serious hikers will find their footing rather on Meru or Kilimanjaro.
