Kenya or Tanzania – which to choose for a safari?

Many tourists want to know the differences between Kenya and Tanzania when planning their safari vacation in Africa. The glib advice is “choose both countries” but if time or cost constraints force you to choose between these two countries, this post describes some of their key safari-related differences, based on our experience.

To get lost is to learn the way – African proverb

There are many reasons to choose one country over the other, such as infrastructure (roads, airports, accommodation, access), relative cost, number of parks, tourist congestion and wildlife density, and these are summarized below.

TIP: The Serengeti-Mara migration is the holy grail of safaris in East Africa, and this takes place at certain times of year within the ecosystem that covers both counties. Therefore, to witness the migration you need to plan around the dates and locations of the migration.

Hint: Tanzania always has some massive wildebeest herds, but Kenya does not.

Kenya’s Maasai Mara vs Tanzania’s Serengeti

In Tanzania you have many choices for dates and locations to see the migrating herds as they munch their way around the Serengeti (see details below). However, in Kenya, depending on when the rainy season starts, the migrating herds are only there from about August to November and only in a small section of Kenya called the Maasai Mara National Reserve (or just ‘the Mara’).

The Mara is a National Reserve (not a National Park) and is home year round to resident lions, cheetahs, elephants, zebras, hippos, but during migration it sees countless wildebeest and zebras and of course thousands of tourists.

During migration, some of the herds (but not all of them) cross from Tanzania’s massive Serengeti park into the Mara. As shown on the map below, the Mara is contiguous with the Serengeti National Park therefore the Serengeti-Mara migration area is one big ecosystem. The Mara is Kenya’s portion and is relatively small (1600 km²), which is about the size of London, England; it is one of the smallest reserves or parks in all of Africa. By comparison, the Tanzania portion (Serengeti Park) is about 10 times bigger (15,000 km²).

The contrast in land size is is one of the big differences between these two countries: most of the migration activity occurs in Tanzania.

However, the Serengeti is such a vast area that you may not see any of the migrating mega-herds during your stay, depending on when and where you go, and on luck.

If your interested mainly in witnessing the migration, here is the comparison of approximate dates for migration events in each country, which can change from year to year depending on the rains or drought conditions in each region:

Tanzania’s migration herds can be seen year around (but avoid rainy April and May), because the migration starts and stops in Tanzania, and some herds do remain in Tanzania without ever moving into Kenya at all.

Kenya’s migration activity typically begins from August to early September when herds start to enter the Mara Triangle (see below), and the herds head south back to Tanzania around October to November, whenever the onset of the short rains is felt.

TIP: Some websites suggest the migration never stops, but actually it does pause on the short grass plains of the southern Serengeti, where the wildebeest would actually prefer to stay year round if they didn’t exhaust their food source there. They don’t walk cross-country for the exercise.


Kenya’s Mara Triangle vs Tanzania’s Lamai Wedge

The Mara Triangle in Kenya (indicated on maps above and below) is more remote than the rest of the Maasai Mara and one of the best places within the Mara to view the migration, because any migrating herds that do cross from Tanzania into Kenya usually pass within this triangle. The triangle is formed by the Mara river, the Oldoinyio Escarpment and the Tanzania border. When we were there, we stayed at the Serena Lodge in the Mara Triangle, and our game drives were noticeably less crowded than other areas of the Mara (click here for our post on that trip).

The Lamai Wedge, shown on map above, is on the Tanzania side, and is the area north of the Mara River, with the Kogatende airstrip as a reference point. Compared to the Mara Triangle, the Lamai area is less congested with tourists and more crowded with wildlife. The Masai Mara overall has many lodges but not that many in the Mara Triangle itself. There are only a dozen safari lodges or camps inside or near the Lamai Wedge. For trip planning, use from July until October, and please don’t tell anyone…


Migration river crossings: Kenya vs Tanzania

If the wildebeest migration is the holy grail of safaris, then wildebeest river crossings are the holy grail of the migration. The river crossings occur in both Kenya and Tanzania.

In Tanzania, river crossings occur in the northern Serengeti, first on the on the Grumeti River around June or July as the herds eat their way north west into and beyond the so called Western Corridor. Other crossings in Tanzania occur August through October as some herds which remain in the Lamai Wedge criss-cross the Mara River.

In Kenya, any herds that cross over into the Kenya will crisscross the Mara river many times during the months they are there before they begin their journey back into Tanzania around November. They can stand at a river 5 minutes or 1 hour before crossing, or decide not to cross at all. Or they can start to cross and then some can just reverse direction.

Sadly, the river crossings often result in tragedy when there are crocodiles nearby, and often there are mass drownings where thousands of wildebeest drown because the river banks are too steep or if the river is flooded.

When comparing river crossings in both countries, there’s a few things to consider. The river crossings in both countries can be spectacular due to the sheer chaos and the number of wildebeest and zebras crossing. But the Kenyan side (Mara river) can offer more spectacular crossings because the river is deeper and doesn’t run dry, as Tanzania’s Grumeti river might do in the dry season. Tanzanian crossings still offers the chaos and crocodiles but usually not on as dramatic a scale as the Mara river on the Kenya side.

River crossings typically occur around August through October in both countries, but are totally unpredictable and we agree with the experts who say that it is futile to plan your trip around river crossings. There’s a more detailed description of the wildebeest migration in our post here.


Calving season: Tanzania’s other great migration highlight

About 500,000 wildebeest calves are born around January and February (give or take a month, depending on the rains), with the mega-herds concentrated on the nutrient rich short-grass plains in the southern Serengeti. The herds can be spread out from Kakesio in the south to the Moru Kopjes in the north, and from the slopes of the western slopes of the Ngorongoro crater (not inside).

With about 8,000 calves born each day, this event attracts numerous predators including cheetahs that normally don’t co-exist with lions. The herds stay in the south until around March, when they begin their migration cycle north west.

Tanzania has more to offer if the massive wildebeest and zebra herds are your targets. It has a longer tourism season, and the Serengeti has more land areas than the Mara and is therefore less congested (except around Seronera). It also has the calving season.

Kenya’s Maasai Mara is a prolific safari destination during the wildebeest migration, it is a relatively small land area especially since the Mara River (which doesn’t run dry in summer) attracts the herds. But it gets very congested. During the height of the migration, no other wildlife area in Kenya will be as impactful as the Mara.

In both countries, outside of migration season, when the migrating herds and predators have moved on to a different area than the one you are visiting, there will still remain some resident wildlife. Resident game remains exceptional along the Mara River and in particular in the Lamai Wedge, with the possibility of finding the Big Five without a lots of other vehicles. However, this is still expansive landscape and diminished wildlife can lead to possible long drives between game sightings.


Beyond Kenya’s Maasai Mara and Tanzania’s Serengeti

Both countries are worth visiting even if you miss the great migration, not only for the landscape but also for the wildife.

Tanzania has two main safari ‘circuits’, a northern circuit and a southern one. In its southern circuit, Tanzania has the largest designated wildlife area in all of Africa: the Selous Game Reserve (over 50,000 km²). The southern circuit is where you go to avoid crowds. The northern circuit includes Lake Manyara, Tarangire, Arusha and Kilimanjaro parks, as well as the the 2nd most famous and very congested destination: the Ngorongoro Crater (click here for our post on the crater).

Kenya is tremendously diverse, with about 50+ parks. Northern Kenya has Lake Turkana (known for migratory birds and crocodiles) and Marsabit National Park, but in both cases, it seems the landscape is as much a draw as the wildlife, not unlike Namibia.

Central Kenya straddles the equator and contains most of the parks, including the Rift Valley with Hell’s Gate, Kenya’s most congested park.

Southern Kenya (south of Nairobi) has the 2nd top safari destination after the Maasai Mara: Amboseli National Park. There is good choice of lodging and a 10 month wildlife season, but because of its proximity to Nairobi, it gets crowded (click here for our post on Kenya and Amboseli). Southern Kenya also contains the largest park in Kenya: Tsavo East National Park known for its elephant and lion populations. The Tsavo region is famous due to the many films and books relating to the pair of man-eating lions from 1900. Chyulu Hills which is part of the Tsavo park area has green hilly landscape and fewer crowds than nearby Amboseli.

FACT: Of all the areas mentioned above, none are more famous for wildlife than the Maasai Mara or the Serengeti.

OPINION: Amboseli boasts about the elephant populations in its marshes and swamps, but the elephant population is much more impressive in Chobe, Botswana which we recently visited. (see our post here about different types of safaris throughout Africa).


Conclusions

Kenya and Tanzania both offer similar tourism experiences, including safaris and sea-sun-sand, but there are obviously some differences between them. One of the key differences for safari goers is congestion. The table below, which measures congestion as number of visitors per square meter, shows that Tanzania’s top safari destination (Serengeti) is far less crowded than Kenya’s top destinations: Maasai Mara, Amboseli, Lake Nakuru and Hell’s Gate. (Note that Aberdare is listed as ‘Other’ (in blue) but it is a park in central Kenya, and Ngorongoro Crater is not listed, but it is a very congested park in Tanzania.)

Both Kenya and Tanzania offer a wide choice of lodging: from luxury to basic and mobile camps to permanent lodges and every combination thereof. Tanzania tries to attract tourists willing to pay for a so called ‘premium wildlife’ experience, the so called high-value low-desnity market. As evidence, during the 2008–09 recession, tourist numbers plummeted across the globe, yet number of premium wildlife seeking tourists in Tanzania were not significantly affected, while Kenya is more willing to compete within the low-value high-volume tourist market (Worldbank report, 2016).

Some other countries we visited, like Botswana and Bhutan also focus more on the high-value low-density (HVLD) tourist market, by restricting supply and targeting the high-end segment of tourism. Others (Kenya, Bali) seem to compete in the low-value high volume (LVHV) market, where thin margins and intense price competition is offset by maximizing the number of tourists. The tradeoff is obvious: low visitor numbers minimizes congestion at popular sites and therefore provides more ‘authentic’ wilderness and cultural experiences.

Disease and other safety issues

Malaria is a problem in both countries and Tanzania has the third largest population at risk of malaria in Africa. Malaria maps show less infection with altitude and worse infection further west near Lake Victoria. Travelers to both Tanzania and Kenya typically vaccinations for hepatitis A, typhoid fever, yellow fever, and polio.

Tsetse flies are a problem in both Kenya and Tanzania. Tsetse flies are vectors for the potentially deadly human sleeping sickness which no vaccine or drug can prevent, only avoidance. In Tanzania the only parks not infested with tsetse flies are Mahale (south west), Udzungwa (south east), and 3 parks in the north: Kilimanjaro, Arusha and Manyara (source: Open Journal of Ecology, 2015, 5, 306-314).

Historically, travel advisories about terror related security problems have affected Kenya, as early as the deadly 1975 bombings in Nairobi to the 2019 killing of 20 people at a Nairobi hotel by islamic militants. Tanzania’s last known terrorist event was in 1998 in Dar es Salaam. However, there are currently advisories against travel in certain areas near Tanzania’s western borders with Mozambique, Burundi and the Democratic Republic of Congo due armed groups, traffickers, kidnappings militant attacks… Click here for our Kenya post, and our post on travel planning for Africa is here.


Mondisti’s Seven Trip Tips: Tanzania vs Kenya for safari destination

1 Tanzania’s main safari destination (Serengeti) is less congested the Kenya’s Maasai Mara, and Tanzania attracts travellers who pay more for less congestion.

2 Kenya’s popular safari destinations are more congested, diminishing the sense of authenticity and quality, and few experienced wildlife enthusiasts visit Kenya’s most popular sites. However Kenya’s central and north areas offer good eco-system diversity.

3 In both countries, there are unexceptional parks that are best avoided because they offer a mediocre safari experience due to congestion and limited range of observable wildlife.

4 Tanzania is the country with the largest concentration of animals per square kilometer in the world, while Kenya’s Olare Motorogi Conservancy is said to have one of the highest wildlife densities in Africa.

5 Timing is everything but you should plan your trip only around the river crossings, unless you have lots of time.

6 Please consider  taking supplies for schools or medical clinics on your next African trip:  http://www.packforapurpose.org/

7 As mentioned above, both Kenya and Tanzania should be at the top of your list if you want an fun African safari experience, so visit both. If we had to choose just one, it would be Tanzania, during migration in the north (September/October) or during calving in the south (January/February).
