Key takeaways

• The two areas are halves of one unfenced ecosystem; the international border is the only line between them.
• Wildebeest spend more of the year in Tanzania, including the January to February calving season, and are usually in the Mara from about July to October.
• The Masai Mara works for short trips from Nairobi; the Serengeti rewards five days or more, normally combined with Ngorongoro.
• Published entry fees differ: Narok County charges non-resident adults USD 100 to 200 per day by season, while TANAPA lists USD 60 to 70 plus 18% VAT for the Serengeti.
• A combined Kenya and Tanzania itinerary removes the need to choose.

Serengeti vs Masai Mara: what is the difference?

The main differences are size, country and management, not wildlife. Serengeti National Park in Tanzania and the Masai Mara National Reserve in Kenya share an open border, and animals cross it freely. The question of Serengeti vs Masai Mara is therefore about logistics and season more than about what lives there.

Size and setting

Narok County’s management plan gives the Masai Mara National Reserve an area of roughly 1,500 km². Tanzania National Parks (TANAPA) puts the Serengeti at around 15,000 km². The Mara is compact, with rolling grassland and the Mara and Talek rivers. The Serengeti has several distinct regions: the southern short-grass plains, the central Seronera valley, the western corridor and the northern woodlands along the Mara River.

Who runs them

The Masai Mara is a county reserve run by the Narok County Government, with the Mara Triangle managed by the Mara Conservancy on the county’s behalf. Private and community conservancies border the reserve. The Serengeti is a national park run by TANAPA and is a UNESCO World Heritage Site.

Where is the wildebeest migration, and when?

The herds move in a year-round loop, spending more months in Tanzania than in Kenya. Rainfall drives the timing, so the pattern below is typical and not a timetable.

• December to March: southern Serengeti and the Ndutu area. TANAPA lists January and February as the calving season.
• April to June: the herds drift through the central and western Serengeti.
• About July to October: northern Serengeti and the Masai Mara, with crossings of the Mara River on both sides of the border.
• November: the herds generally head south again with the short rains.

River crossings happen in both countries and cannot be scheduled. Some visitors wait days and see none; others arrive at the right hour. Our wildebeest migration safari page explains how we plan around this.

Outside the migration months, both areas keep strong resident populations of lions, leopards, cheetahs, elephants and plains game.

Is the Masai Mara or Serengeti better for a first safari?

For a first safari of under a week, the Masai Mara is usually the easier choice. It is a half-day drive or a short scheduled flight from Nairobi, and its small size means good game viewing begins soon after you enter.

The Serengeti suits travellers with more time. Most visitors reach it from Arusha as part of the northern circuit, with Tarangire and the Ngorongoro Crater on the way. That makes for a richer journey, and a longer one. Our guide to the Tanzania northern circuit sets out the usual routing.

Choose the Masai Mara if

• you have three or four days
• you are travelling between about July and October and want a chance of migration herds
• you want to add Lake Nakuru, Lake Naivasha or Ol Pejeta by road

Choose the Serengeti if

• you have five days or more
• you are travelling between December and March and want the calving season
• you want to combine it with the Ngorongoro Crater

How do park fees compare?

At the time of writing (November 2026), the published daily entry fee is lower in the Serengeti all year, and the gap is widest from July to December. The two authorities structure their charges differently, so compare whole itineraries and not single fees.

Masai Mara National Reserve

The Narok County Finance Act sets non-resident adult entry at USD 100 per day from January to June and USD 200 per day from July to December. Children aged 9 to 17 are listed at USD 50. A ticket covers 6.00 am to 6.00 pm whatever time you enter. Conservancies beside the reserve set their own fees.

Serengeti National Park

TANAPA’s Serengeti page lists a conservation fee of USD 70 for international adults. A TANAPA tariff document shows a lower low-season rate of USD 60 from mid-March to mid-May and states that all charges exclude 18% VAT. That works out at roughly USD 71 to 83 per adult per day. TANAPA also charges separate per-night concession or camping fees for visitors who sleep inside the park.

Both authorities revise fees from time to time. Confirm the current figures with Narok County and TANAPA, or ask us for an itemised quote.

How do you get to each, and how long do you need?

The Masai Mara is reached from Nairobi, and the Serengeti normally from Arusha. From Nairobi, travellers bound for the Serengeti usually cross the border at Namanga for Arusha, or at Isebania for the northern Serengeti.

Two or three nights give a fair Mara experience. The Serengeti needs three or four nights inside the park, because distances between its regions are long and a day is lost to travel at each end.

Entry rules differ too. Kenya uses an electronic travel authorisation, and Tanzania has its own visa. The East Africa Tourist Visa does not cover Tanzania. Check both countries’ official immigration websites before you book flights.

Can you visit both on a Kenya Tanzania safari?

Yes. A combined Kenya Tanzania safari is the simplest answer for anyone who cannot decide, and it follows the ecosystem as the animals use it. Allow eight days or more so that the border crossing does not eat into game-drive time.

Vehicles generally change at the border, as safari vehicles are licensed in one country. A common order is Masai Mara first, then the Serengeti, Ngorongoro and Tarangire, finishing in Arusha, or the same route in reverse. Our Kenya Tanzania safari page shows how the days fit together.

Frequently asked questions

Is the Serengeti bigger than the Masai Mara?

Yes. Serengeti National Park covers around 15,000 square kilometres according to Tanzania National Parks, while the Masai Mara National Reserve covers roughly 1,500 square kilometres. The two join at the Kenya and Tanzania border and form one ecosystem.

Which is cheaper, the Serengeti or the Masai Mara?

It depends on the month and the trip. At the time of writing, published entry fees for non-resident adults are USD 100 to 200 per day in the Masai Mara by season and USD 60 to 70 plus 18% VAT in the Serengeti. A Serengeti trip usually needs more days and longer transfers, which adds cost.

Do both parks have the Big Five?

Lions, leopards, elephants and buffalo are found in both. Black rhinos are present in small numbers in each ecosystem and are seldom seen. Travellers who want better rhino chances often add Lake Nakuru or Ol Pejeta in Kenya, or the Ngorongoro Crater in Tanzania. No sighting can be guaranteed.

Can I see river crossings in the Serengeti?

Yes. The Mara River flows through the northern Serengeti as well as the Masai Mara, and herds cross it on both sides of the border, usually between about July and October. Crossings depend on the animals and the weather and cannot be predicted.

Do I need separate visas for Kenya and Tanzania?

Yes. Kenya requires most visitors to hold an electronic travel authorisation, and Tanzania issues its own visa. The East Africa Tourist Visa covers Kenya, Uganda and Rwanda only. Check the official immigration websites of both countries for the rules that apply to your passport.
