Tanzania safari planning guide: Best Places to Visit in Africa in May
May is an excellent shoulder-season month for Tanzania safaris, as the long rains taper off and the Grumeti River crossing season begins. Western Corridor camps position guests for early migration crossings, while central Serengeti delivers lush green landscapes, exceptional birding, and significantly lower rates than the approaching peak season.

Western Serengeti & Grumeti — Herds Mass Before Crossings
By late May the migration edges toward the western corridor. Herds stack along the Grumeti River, big crocs wake up, and Singita/Grumeti reserves feel wonderfully uncrowded. Expect verdant plains, dramatic skies and the first hints of river drama if rains ease early.
What
- Herds staging near Grumeti River, predator pressure building
- Storm-lit plains with pockets of sunshine
Why
- Pre-crossing excitement without peak July crowds
- Access to walking safaris, riding & hot air balloons in quiet season
When to book
- Hold western corridor camps 6–9 months out—inventory is small
- We monitor road conditions; arrange fly-ins if black cotton soil lingers

May Safari Guide
Why May is Exceptional for Adventurous Safari Travelers
May represents the heart of East Africa's long rains—a time when most travelers stay away, creating extraordinary opportunities for adventurous safari enthusiasts seeking authentic wilderness experiences, dramatic landscapes, and exceptional value. While conventional wisdom suggests avoiding the wet season, experienced safari travelers know that May delivers unique wildlife encounters impossible during the crowded dry season.
In Tanzania's Serengeti, the Great Wildebeest Migration reaches the western corridor during May, preparing for the first major river crossings of the year at the Grumeti River. Unlike the predictable southern plains concentration of January-March or the dramatic Mara River crossings of July-October, May offers the thrill of tracking dispersed herds through lush, green landscapes with virtually no other tourists present. The Serengeti reveals its most beautiful face—emerald plains, wildflower meadows, and dramatic storm clouds that create photographer's-dream conditions.
May's advantages extend far beyond reduced crowds and lower prices (often 40-50% less than peak season). The wet season brings baby animals across multiple species—not just wildebeest, but also zebras, gazelles, impalas, and predators with cubs. Birdlife reaches its absolute zenith with both resident breeders and Palearctic migrants present simultaneously. Photography opportunities are spectacular, with soft light, dramatic skies, and vibrant landscapes that dry-season travelers never witness.
Ideal travellers
- Photographers loving storm drama, green backdrops, no vehicle crowds
- Birders chasing peak diversity, breeding displays and migrants
- Adventurous guests who don’t mind showers and want big savings
- Primate and rainforest fans willing to embrace mud for intimacy
Where to go
- Western Serengeti / Grumeti for migration staging & early crossings
- Ngorongoro, Tarangire, Manyara for lush Big Five + flamingos
- Ruaha / Nyerere for wild green wilderness (access dependent)
- Zanzibar/Pemba/Mafia for spa-forward finishes between showers
Highlights
- Pre-crossing herd build-up at Grumeti; giant crocs staging
- Baby boom across plains game; predators with cubs
- Outrageous birding: residents breeding + migrants still present
- Soft light, storm clouds, emerald kopjes with near-zero crowds
Tanzania
Migration west, green glory
Western Corridor & Grumeti
May marks the migration's arrival in the Serengeti's western corridor, one of the most beautiful and least-visited regions of the park. As the long rains transform the landscape, massive wildebeest and zebra herds move northwest from the central Serengeti toward Lake Victoria, concentrating along the Grumeti River.
Migration herds arrive in increasing numbers throughout May, with early crossings possible late May (though main crossings typically June). Crocodiles position themselves in anticipation (some individuals exceed 16 feet), and large hippo pods are permanent residents in Grumeti pools.
- Lions following herds from central; western corridor resident prides capitalizing on prey influx
- Leopards in riverine forests and Grumeti woodland; cheetahs on open western plains
- Spotted hyena clans swelling in size; wild dogs occasionally present (rare but possible)
- Virtually no other tourists—you may be completely alone at sightings
- Dramatic landscapes—rolling hills, whistling thorn forests, riverine vegetation
- Some roads may be muddy (4x4 essential, but experienced guides navigate easily)
Stay: Singita Grumeti (ultra-luxury), Kirawira Serena Camp, Mbalageti Serengeti, seasonal migration camps.
Central Serengeti (Seronera)
While migration herds depart westward in May, the central Serengeti's Seronera Valley continues delivering exceptional wildlife viewing thanks to its permanent resident populations. Resident predators remain active with excellent leopard viewing in riverine fig trees along Seronera River.
- Large lion prides (some of the Serengeti's most famous prides are Seronera residents)
- Cheetahs on Seronera plains; elephants, buffalo, giraffes, hippos, crocodiles year-round
- Kopjes hosting hyraxes, klipspringers, and occasional leopards
- Beautiful green landscapes with lush vegetation; exceptional bird photography
- Fewer tourists than dry season; excellent accommodation availability and rates
Stay: One Nature Nyaruswiga (eco-luxury), Taasa Lodge (boutique), Dunia Camp, Serengeti Serena Safari Lodge.
Ngorongoro Crater
The Ngorongoro Crater's unique ecosystem and permanent wildlife populations ensure exceptional viewing regardless of season. May delivers the crater at its most beautiful—lush, green, and uncrowded.
- Black rhinos (approximately 30 individuals)—East Africa's most reliable rhino viewing
- Large elephant bulls with impressive tusks; lion prides (60-70 individuals)
- Massive buffalo herds (sometimes exceeding 1,000 animals); hippo pools at Ngoitoktok Springs
- Flamingo flocks on Lake Magadi; spotted hyenas, golden jackals, serval cats
- Crater floor lush and vibrant green; wildflowers blooming prolifically
- Morning mist creates atmospheric photography; significantly fewer vehicles than dry season
Stay: Entara Olmara Camp, Ngorongoro Crater Lodge (ultra-luxury), Lemala Ngorongoro, The Highlands (geodesic domes).
Tarangire & Manyara
May Tarangire offers a completely different character than the famous dry season concentrations (June-October), but delivers its own unique beauty and wildlife experiences. Large elephant herds are dispersed throughout the park, with lions, leopards, and cheetahs present (though harder to locate in thick vegetation).
- Over 550 recorded bird species with peak breeding activity; Palearctic migrants still present
- Massive baobab trees against green grass create iconic African scenes
- Lush green landscapes—absolutely spectacular photography; very few tourists
- Beautiful swamps full of water; Tarangire River flowing strongly
- Baby animals of multiple species; tree-climbing lions and flamingos at Manyara
Southern circuit (Ruaha, Nyerere)
Wild, remote, great value: elephants, lions, leopards, wild dogs, sable, kudu. Rufiji boats shine; some tracks tough—fly-ins or route changes as needed.
Rainforest & lakes add-ons
Udzungwa waterfalls, Mahale chimps (weather-permitting), Eyasi culture, Karatu coffee. Lush, butterfly-rich, superb birding if you embrace rain.
Beyond Tanzania
Kenya, Uganda & Rwanda in May
Kenya long rains
Masai Mara green, quiet, low rates; resident big cats and newborn plains game. Amboseli offers elephants with Kili on clear mornings; Samburu stays drier with the Special Five; Tsavo vast and emerald.
Uganda & Rwanda
Wettest month but gorilla/chimp treks run year-round; fewer trekkers, easier permits, discounted lodges. Expect mud, mist and intimate encounters. Boat safaris on Kazinga/Nile still superb; Akagera remains accessible.
Wildlife & nature
Why May feels electric
Migration lines stretch toward Grumeti; bulls still rutting; predators trail dispersed herds; baby animals everywhere. Storm-cleared air, emerald hills and wildflowers create rare photographic moods.
Migration dynamics
- Early May: herds leaving central; dispersed tracking
- Late May: concentrate western corridor; early Grumeti crossings possible
- Rutting continues; predators shadow columns
Predators
- Lions/prides follow herds west; cubs visible
- Leopards along Seronera/Grumeti riverine forests; tree kills
- Cheetahs on central/western plains between showers
- Hyena dens active; wild dogs in Ruaha/Nyerere
Birding peak
May represents absolute peak birding with both Palearctic migrants and resident breeders present simultaneously. Nest building widespread, courtship displays active, chicks fledging, territorial behavior intense.
- Secretary birds nesting; kori bustards displaying; ostriches in breeding plumage
- Fischer's lovebirds (Tanzania endemic); yellow-collared lovebirds (Tarangire)
- African fish eagles breeding; crowned cranes with chicks; six vulture species
- Flamingos on alkaline lakes; storks, herons, egrets breeding; kingfishers active
- Raptors: bateleur, martial, tawny eagles; augur buzzards breeding
Photo conditions
Soft, diffused light; storm clouds; rainbows; green backgrounds; few vehicles to block shots. Protect gear with covers/dry bags and keep cloths handy.
Activities & experiences
What to do in May
Game drives
May game drives offer unique character: Morning drives typically feature dry weather, good wildlife activity, beautiful light, and cool comfortable temperatures. Afternoon drives may encounter rain (usually brief), dramatic lighting between storms, and wildlife active before/after rain providing storm photography opportunities.
Some roads may be muddy (exciting, adventurous), but 4x4 vehicles handle conditions well with experienced guides navigating skillfully. More tracking and exploration is required as dispersed wildlife means longer searches, but it's rewarding when you find animals with no crowds. Radio networks help locate wildlife, and flexibility in timing is appreciated.
Walking safaris
Ngorongoro highlands, Nyerere, Ruaha, Kenyan conservancies—lush, scented, track-rich; bring waterproofs and good boots.
Hot air balloons
Fly Seronera or (weather allowing) western corridor; green vistas and migration lines. Weather-dependent; keep flexible.
Boat safaris
Rufiji (Nyerere), Kazinga Channel, Victoria Nile, Lake Ihema—peak flows, hippos, crocs, prolific waterbirds; run even in rain.
Primate trekking
May primate trekking requires preparation but delivers: Easy permit availability, lower accommodation costs, fewer trekkers (intimate experiences), lush forest beauty, and active primates (babies playing). Quality waterproof gear mandatory, good fitness required for muddy slippery trails, porters strongly recommended, gaiters protect from nettles. Gorillas unaffected by weather—one hour with gorillas magical regardless of rain.
Culture & coast
Lake Eyasi Hadzabe/Datoga, Karatu coffee, spice tours, Stone Town rooftops. Islands are quieter; expect warm seas with some cloudiness.

Booking timeline
1–3 months advance: Accommodation (excellent availability), gorilla permits (good availability), internal flights. Last-minute deals possible.
Crowd levels: Very low throughout, excellent availability, flexibility appreciated by camps.
Where to Stay in May
Western Corridor camps (Singita Grumeti, Kirawira Serena, seasonal migration mobiles) position guests for the early Grumeti crossing season and should be confirmed for May opening dates annually. Central Serengeti permanent properties (Seronera lodges) continue or take a short break during the shower. The rain transforms the landscape: dust settles, air clears, grass begins greening, and dramatic storm clouds produce the kind of photography conditions that photojournalists specifically travel to capture. May's short rains are a feature, not a bug. Browse all accommodations.
Packing essentials
Critical items: Quality waterproof rain jacket, waterproof day pack, waterproof hiking boots (gorilla trekking), dry bags for electronics, lens cleaning cloths, zip-lock bags for cameras, quick-dry clothing, warm fleece (cool mornings/evenings).
Photography gear: Rain covers for camera/lenses, moisture-absorbing packets, backup equipment, lots of memory cards.
