Kenya & Tanzania parks — the numbers that will blow your mind
Verified park sizes, wildlife census data, conservation milestones and climate facts — all cited from KWS, UNESCO, TAWA, IUCN and Ol Pejeta. This is what the raw data looks like for the greatest wildlife destination on Earth.
Climate & Weather
On the equator — but not what you think
Kenya straddles the equator. Tanzania lies just below it. Most people hear "equatorial Africa" and picture oppressive heat. What they get instead is one of the world's most pleasant safari climates — because the Mara, Amboseli, Nairobi and the Serengeti all sit at altitude.
Nairobi stands at 1,795m above sea level. The Masai Mara is at 1,500m. The Serengeti plateau averages 1,500m. Ngorongoro Crater rim reaches 2,400m. At these elevations, daytime temperatures in the game parks average a pleasant 25–28°C, and nights drop to a cool 12–16°C.
There is no "bad time" to visit East Africa. There is simply a best time for what you want to see.
Dry & Warm
Short dry season. Excellent game viewing — thin vegetation and animals around water. Calving season begins in southern Serengeti. Very good value for accommodation.
Long Rains
Green season. Lush landscapes, newborn wildlife, exceptional birding, fewer tourists. Some roads become challenging — but prices drop significantly and parks are beautifully uncrowded.
★ Peak Season
Best game viewing of the year. The Great Migration is in the Mara (Jul–Oct). Dry weather, cool nights, maximum wildlife concentration at water sources. Book accommodation far in advance.
Short Rains
Brief afternoon showers keep landscapes green. Migration herds return south to Tanzania. Excellent photographic light and significantly fewer tourists than peak season.
🇰🇪 Kenya's National Parks & Reserves
Kenya protects 25% of its total land area as wildlife territory
Kenya Wildlife Service (KWS) manages 22 national parks, 28 national reserves, 5 marine parks and 6 marine reserves — covering approximately 68,000 km² of protected habitat. Sources: kws.go.ke
Masai Mara National Reserve
The most famous wildlife reserve on Earth. Measured, and verified.
+ ~2,000 km² private conservancies = 3,500 km² managed Mara ecosystem
The Masai Mara National Reserve alone covers 1,510 km² — approximately the size of Greater London. Add the surrounding private conservancies (Olare Motorogi, Naboisho, Ol Kinyei, Mara North and others) and the managed Mara ecosystem reaches approximately 3,500 km². The greater Mara-Serengeti trans-boundary ecosystem extends to a staggering 30,000 km² — larger than Belgium.
The Mara has the highest density of resident lion prides in Africa and consistently records all of the Big Five on a single morning game drive during peak season.
Amboseli National Park 🐘

Conservation Success Story
Ol Pejeta Conservancy: How one piece of land brought rhinos back from the brink
Ol Pejeta Conservancy in Laikipia, Kenya, covers 360 km² — and it is the most significant black rhino sanctuary in East Africa, and home to the world's last two northern white rhinos.
When conservation efforts began at Ol Pejeta, the black rhino was listed as Critically Endangered (IUCN Red List). Through rigorous anti-poaching operations, habitat management, and a model that combines conservation with community benefit and tourism, Ol Pejeta has built a black rhino population that is now the largest single population in East Africa — with over 105 black rhinos now thriving on the conservancy.
Their model — proving that conservation and commerce are not in conflict — is now studied and replicated across the continent.
Scale in Context
Kenya's parks vs European countries & regions
Numbers land differently when you compare them to places you know. This is how big Kenya's wildlife areas actually are.
| Kenya Park / Ecosystem | Size (km²) | European Equivalent | What That Means |
|---|---|---|---|
| Greater Mara-Serengeti Ecosystem | ~30,000 | ≈ Belgium (30,528 km²) | The full trans-boundary ecosystem shared by Kenya & Tanzania is the size of an entire country |
| Tsavo East + West (combined) | 22,812 | Larger than Wales (20,779 km²) | Kenya's largest park is bigger than all of Wales — and it shares a border with Amboseli |
| Tsavo East | 13,747 | ≈ Northern Ireland (13,843 km²) | Tsavo East alone is the size of Northern Ireland, and still one of the least-visited parks in Kenya |
| Tsavo West | 9,065 | ≈ Cyprus (9,251 km²) | An entire Mediterranean island's worth of protected wilderness |
| Masai Mara National Reserve | 1,510 | ≈ Greater London (1,572 km²) | The core reserve is modest — but what it contains per km² is unmatched anywhere |
| Masai Mara + All Conservancies | ~3,500 | ≈ Luxembourg (2,586 km²) × 1.35 | Including all private conservancies, the managed Mara landscape is larger than Luxembourg |
| Kenya Total Protected Areas | ~68,000 | ≈ Ireland + Northern Ireland (89,000 km²) | Kenya's entire protected wildlife estate is nearly the size of the island of Ireland |
| Ol Pejeta Conservancy | 360 | Larger than Singapore (728 km²) × 0.5 | Half the size of Singapore — and home to the last 2 northern white rhinos on Earth |
| Amboseli National Park | 392 | ≈ 4.6× the area of Oslo municipality (454 km²) | A relatively compact park that packs extraordinary elephant and big cat sightings per km² |
🇹🇿 Tanzania's National Parks & Conservation Areas
Tanzania has placed 38% of its entire land area under formal wildlife protection
Tanzania's protected wildlife territory covers approximately 364,000 km² — nearly the size of Germany (357,114 km²). It includes 22 national parks, 29 game reserves, 40 game controlled areas, 1 conservation area and numerous forest reserves. Sources: tawa.go.tz · tanzaniaparks.go.tz
Serengeti National Park · UNESCO World Heritage 1981
The Serengeti is bigger than you can comprehend. The data helps.
The Serengeti covers 14,763 km² — larger than Northern Ireland (13,843 km²) and nearly the size of the US state of Connecticut. It was inscribed as a UNESCO World Heritage Site in 1981, making it one of the earliest and most internationally recognised protected areas in Africa.
The name comes from the Maasai word siringet — "the land that goes on forever." When you stand inside it, you understand immediately why.
The park has been continuously researched by the Frankfurt Zoological Society since the 1960s and is home to the world's largest lion population — an estimated 3,000 lions within the ecosystem.

Tanzania in Scale
Tanzania's parks vs countries you know
Tanzania protects a land area roughly the size of Germany. These comparisons make that tangible.
| Tanzania Park / Area | Size (km²) | European Equivalent | Why It Matters |
|---|---|---|---|
| Tanzania Total Protected Areas | ~364,000 | ≈ Germany (357,114 km²) | Tanzania's entire protected wildlife estate is almost exactly the size of Germany. 38% of the whole country. |
| Nyerere / Selous National Park | 54,600 | Larger than Denmark (42,924 km²) | Africa's largest protected area is bigger than Denmark. And fewer than 1% of Tanzania's tourists visit it. |
