Lions of the Masai Mara: Famous Prides and Sightings

Entice Africa October 26, 2026Safari, Wildlife & Conservation

The Masai Mara is among Kenya’s most important lion strongholds. In 2025 the Mara Predator Conservation Programme (MPCP) estimated 481 lions over one year old in its 2,713 km² study area, up from 465 in 2024, or about 17.5 lions per 100 km². That area covers the Maasai Mara National Reserve and the conservancies around it.

This guide explains what those figures mean, where lion density is highest, what is on record about the Marsh Pride of Big Cat Diary fame, and what threatens the lions. For everything else about the trip, start with our Masai Mara safari guide.

Masai Mara lions at a glance

These are the 2025 survey figures, with 2024 alongside where the report gives it.

The survey counts lions over one year old, so cubs are not included. If you would like to look for these lions yourself, our 3-Day Maasai Mara Roar & Roam Safari starts from USD 1,420 per person, based on a midrange itinerary in low season for two people sharing. Prices depend on season, group size and lodge choice.

How many lions live in the Masai Mara?

The MPCP has run annual lion surveys since 2014. The 2025 survey was its 12th consecutive year of density estimates, and it uses a statistical method called spatially explicit capture-recapture. The headline result is 481 lions over one year old, against 465 the year before, with density rising from 16.5 to 17.5 lions per 100 km². The report concludes that the Mara remains one of Kenya’s most important lion strongholds and that numbers have stayed stable despite land-use pressure.

What changed between 2024 and 2025

The overall rise hides differences between areas. The Maasai Mara National Reserve unit recorded 183 lions in 2025, down from 195 in 2024. The Mara Triangle was steady, with 72 lions against 71. Because the total went up while the reserve figure went down, the conservancies around the reserve clearly matter to the Mara’s lions. Survey estimates carry some uncertainty, so a change of a dozen lions in one year is best read alongside later surveys.

What the count leaves out

Three limits are worth knowing. The count covers lions over one year old, so it does not include cubs. It covers a 2,713 km² study area, not every lion that uses the wider Greater Mara. And it comes from one survey season, August to October. Treat it as a reliable guide to scale rather than a head count of every lion you might meet.

Where Masai Mara lion density is highest

The report gives lion numbers for the reserve, the Mara Triangle and 15 conservancies. Three conservancies were above 20 lions per 100 km² in 2025. The table shows selected areas, ordered by density.

Source: MPCP survey report. Density tells you how many lions share a space, not how easy they are to see on a given drive, so read it as a guide to where lions are likely to be rather than a promise. Nature Kenya notes that about 70 per cent of the wildlife of the wider ecosystem lives outside the gazetted reserve, which helps explain why the conservancies figure so prominently in the lion counts.

The Marsh Pride and Big Cat Diary

The Marsh Pride is linked to Musiara Marsh and to the BBC series Big Cat Diary, which National Geographic describes as long-running and hugely popular.

The poisoning of December 2015

National Geographic reported on 7 December 2015 that five Marsh Pride lions had eaten a poisoned cow carcass on the Saturday night before. Two died, including the lioness Bibi, and three were treated. Six vultures that probably fed on a dead lion also died, and necropsies found traces of the pesticide carbofuran. At least two people were arrested and arraigned in Narok on 8 December. The zoologist Jonathan Scott, coauthor of a book about the pride, was among those quoted.

The article does not give the size of the pride, and we could not confirm its current size or membership. Prides change over the years, so the lions you meet may not match the ones you remember from television. Your guide will know which prides are active in the area you are visiting.

Where and how to see lions in the Masai Mara

In the reserve and the Mara Triangle

The reserve unit held 183 lions in 2025 and the Mara Triangle held 72, the two largest counts of any area in the survey. Lions are one of the Big Five, and all five can be seen in the Mara. Our guide to the Big Five in the Masai Mara shows where and when to find the others.

In the conservancies

Ol Kinyei, Naboisho and Olare-Motorogi had the highest densities in 2025, at 28.56, 25.01 and 21.98 lions per 100 km². Naboisho also held 52 lions, the largest number among those three. If lions are your priority, say so when you ask for a quote so the planner can build the itinerary around them. For the other big cats, see our guide to cheetahs and leopards in the Masai Mara.

Practical tips for lion sightings

• Ask your guide what has been seen recently and where.
• Early morning and late afternoon drives are usually the most productive for big cats, because lions tend to rest through the heat of the day.
• Bring binoculars or a camera with a zoom lens, so you can watch from where your guide parks without asking the vehicle to move closer.
• Stay in the vehicle, keep your voice low and follow your guide on how close to go.
• Allow several game drives. No survey figure guarantees a sighting on a particular day.

Cubs, the sex ratio and threats to the lions

A shortage of adult males

The finding to watch in the 2025 survey is the sex ratio. The report estimates about 3.3 females for every male in 2025, compared with about 1.7 in 2024, and says this points to a much lower share of adult males. It lists possible causes: conflict between people and wildlife, retaliatory killing, competition for territory and the risks lions face when they disperse.

The report links a shortage of males to unstable prides, takeovers by new males, infanticide and lower cub survival. For visitors, that is a reminder that cub sightings are never guaranteed.

Poisoning and conflict

The Marsh Pride poisoning shows how a single carcass laced with pesticide can kill lions and vultures together. Human-wildlife conflict and retaliatory killing are among the possible causes the report names for the shortage of males, although it does not claim to have found a single cause.

Land-use pressure

The report says lion numbers have stayed stable despite land-use pressure. Much of the Mara’s wildlife lives outside the reserve boundary, so how the land around it is used affects the lions directly. The same survey shows how fragile small populations can be. It counted only 16 resident independent adult cheetahs in the study area in 2025, up from 12 in 2024, and describes that resident population as worryingly small.

Frequently asked questions

How many lions are there in the Masai Mara?

The MPCP’s 2025 survey estimated 481 lions over one year old in a 2,713 km² study area covering the reserve and the surrounding conservancies, up from 465 in 2024. Cubs are not in that figure, and it does not cover the whole Greater Mara.

What is the Marsh Pride?

The Marsh Pride is a lion pride linked to Musiara Marsh and to the BBC series Big Cat Diary. It was in the news in December 2015, when five of its lions ate a poisoned carcass and two died. We could not confirm the pride’s current size, so ask your guide about the prides active in your area.

Where is the best place to see lions in the Masai Mara?

The highest densities in 2025 were in the Ol Kinyei, Naboisho and Olare-Motorogi conservancies. The reserve and the Mara Triangle hold the largest numbers overall, at 183 and 72 lions. Density is a guide, not a guarantee, so give yourself several game drives.

Can you see lions in the Masai Mara all year?

Lions are resident cats rather than migrants, so there is no month in which they leave the Mara. How easy they are to find on a particular drive still varies, and more days give you better odds. Tell us your dates and the planner will advise on what to expect.

Are Masai Mara lions under threat?

The survey shows stable numbers, but it also flags a sharp rise in the ratio of females to males, which it links to possible causes such as human-wildlife conflict and retaliatory killing. Poisoning, as in the 2015 Marsh Pride case, remains a risk to lions and scavengers.

Will I see lion cubs on safari?

Possibly, but nobody can promise it. The survey leaves cubs out of its count, and the report warns that a shortage of adult males can mean takeovers, infanticide and lower cub survival. Ask your guide where cubs have been seen recently.

How much does a lion safari in Kenya cost?

Our 3-day Maasai Mara safari starts from USD 1,420 per person and our 9-day Big Cat Safari from USD 4,197 per person, based on a midrange itinerary in low season for two people sharing. Prices depend on season, group size and lodge choice. For a tailor-made quote, send us your dates and we reply within 6 hours.
