Ishasha Tree Climbing Lions

There is a moment that every visitor to Uganda’s Ishasha sector describes the same way. You are scanning the open savannah — watching Uganda kob graze in the golden morning light, following the slow drift of elephants across the far horizon — when your guide quietly tells you to stop looking at the ground and look up. And there, sprawled across the broad, sun-warmed branches of a giant sycamore fig tree, are lions. Not one or two, but an entire pride. Tails dangling lazily in the breeze. Eyes half closed. Kings and queens of the jungle, resting in the canopy like enormous, amber-eyed cats in a dream.

This is the Ishasha sector of Queen Elizabeth National Park, and what you are witnessing is one of the rarest wildlife behaviours on the face of the earth. Uganda is one of only two places in the world where lions regularly, consistently, and habitually climb trees — a phenomenon so unusual, so visually arresting, and so completely unexpected that it draws wildlife photographers, safari enthusiasts, and curious travelers from across the globe year after year.

This is everything you need to know about the Ishasha tree climbing lions — and why no Uganda safari is truly complete without them.

Where Is Ishasha and What Makes It Unique?

The Ishasha sector occupies the remote southern portion of Queen Elizabeth National Park, sitting in the extreme southwest of Uganda close to the border with the Democratic Republic of Congo. It is a place of remarkable wildness — vast open grassland plains dotted with enormous sycamore fig trees, riverine forest corridors tracing the course of the Ntungwe River, and a sense of space and solitude that feels entirely different from the busier northern sections of the park around Mweya and the Kazinga Channel.

Queen Elizabeth National Park itself is Uganda’s most visited national park and one of the most biodiverse protected areas in Africa. Covering 1,978 square kilometres, the park supports over 95 mammal species, 600 bird species, and a rich variety of reptiles, amphibians, and plant life. It lies within the greater Albertine Rift ecosystem — one of the most biologically important regions on the African continent — and shares a wildlife corridor with Virunga National Park in the DRC to the west.

While the park’s northern Kasenyi plains, the Kazinga Channel boat cruise, and the chimpanzee tracking in Kyambura Gorge draw the majority of visitors, it is the Ishasha sector in the south that holds the park’s most extraordinary secret. The drive from the main park area to Ishasha takes approximately two to three hours through scenic countryside, and the sense of arriving at something genuinely remote and wild grows with every kilometre.

For travelers planning to combine Ishasha with a gorilla trekking experience — which is the most popular itinerary in southwest Uganda — our 3 Days Bwindi Gorilla Trekking Safari sits just a short drive from the Ishasha sector and pairs perfectly for a multi-day adventure. The 8 Days Uganda Big Five Safari Adventure also includes time in Queen Elizabeth National Park and can be tailored to include the Ishasha sector.

Why Do the Ishasha Lions Climb Trees?

It is one of Africa’s great wildlife mysteries, and the honest answer is that scientists still do not fully agree. What is certain is that the lions of Ishasha are not a unique subspecies — they are the same African lion as their ground-dwelling cousins across the continent. And yet they have developed this extraordinary arboreal habit with a consistency and regularity seen nowhere else in East Africa.

Several compelling theories have been proposed. The most widely accepted is thermal comfort: the open savannah floor in Ishasha becomes intensely hot during the middle of the day, and the boughs of the tall fig trees offer access to cooling breezes that are simply not available on the ground. Climbing is a natural, energy-efficient way for the prides to regulate their body temperature without expending energy moving to shade elsewhere.

A closely related theory involves insect avoidance. The lower grasslands of Ishasha are dense with tsetse flies and other biting insects that plague ground-level animals during the heat of the day. From the elevation of a fig tree branch — three, four, even six metres above the ground — the lion is largely above the worst of the insect activity, able to rest undisturbed.

A third theory points to strategy: from an elevated perch, a lion enjoys a commanding view of the surrounding plains, able to monitor the movements of Uganda kob, buffalo, and topi herds across a wide area while remaining concealed within the canopy. The fig tree becomes both a resting place and a natural watchtower.

Perhaps most fascinatingly, researchers believe that cultural transmission plays a central role in perpetuating this behaviour. Cubs learn to climb from their mothers — who learned from their own mothers before them — meaning that this is not simply an instinctive response to the environment but a learned tradition passed down through generations of Ishasha lion prides. It is, in a meaningful sense, a lion culture unique to this part of the world.

The Lion Prides of Ishasha — What You Will See

The Ishasha sector is home to several lion prides, with an estimated 20 to 35 individuals currently living within the area. The game drives in Ishasha focus primarily on the fig tree lines along the Ntungwe River — the southern circuit of the sector — where the prides spend the majority of their daylight hours during the dry seasons in particular.

The best time to observe the tree climbing behaviour is between mid-morning and mid-afternoon — roughly 10 a.m. to 3 p.m. — when the day is at its hottest and the lions seek the comfort and elevation of the fig tree branches. During the cooler hours of early morning and late afternoon, the prides are more likely to be found on the ground, hunting or moving between territories. However, dedicated early morning and late afternoon game drives offer their own extraordinary rewards, with the possibility of witnessing the lions on the move, cubs at play, or — on a truly exceptional morning — a pride returning from a hunt as the sun rises over the savannah.

Because Ishasha receives far fewer visitors than the northern section of Queen Elizabeth National Park, the experience here is deeply personal. There are no convoys of safari vehicles, no competition for viewpoints. When you find a pride stretched across a fig tree, it is often just you, your guide, and the lions — an intimacy that is increasingly rare in East Africa’s most visited wildlife destinations.

The Uganda Wildlife Authority monitors the lion prides daily, and park rangers can direct your guide to the most recent sightings, significantly improving your chances of a successful encounter. Game drives in Ishasha are conducted in 4WD safari vehicles with open roofs, giving photographers and wildlife watchers unobstructed views into the canopy above.

Beyond the lions, Ishasha is home to large breeding herds of elephants, impressive buffalo aggregations, Uganda kob, topi, waterbuck, hyenas, warthogs, and the occasional leopard. The birdlife is outstanding — the sector sits at the edge of the Guinean and Congolian forest zones, giving it a bird list that includes both savannah and forest species. The rare lappet-faced vulture, martial eagle, and numerous species of starling and sunbird are regularly recorded.

Our 7 Days Ultimate Uganda Primate Safari can be designed to include time in the Ishasha sector as part of a broader Queen Elizabeth National Park visit, combining the tree climbing lions with chimpanzee tracking in Kyambura Gorge and the famous Kazinga Channel boat cruise. Frena Adventures also offers superb Uganda safari holidays that cover the full breadth of Queen Elizabeth National Park in expertly guided itineraries.

Combining Ishasha with Bwindi Impenetrable Forest

One of the greatest advantages of the Ishasha sector’s geography is its position along the natural travel route between Queen Elizabeth National Park and Bwindi Impenetrable National Park — Uganda’s premier gorilla trekking destination. Most travelers doing a southwest Uganda circuit will pass through or near Ishasha as they journey between these two iconic parks, making it an ideal and logical addition to any gorilla trekking itinerary.

A typical routing might take you from Kampala southwest to Queen Elizabeth National Park for a Kazinga Channel boat cruise and game drives on the Kasenyi plains, then south through Ishasha for tree climbing lion game drives, before continuing to the Bwindi Forest sector for gorilla trekking. This itinerary covers some of the most spectacular wildlife in Uganda in a beautifully compact and logical sequence.

Our 4 Days Double Gorilla Trekking Escape is an excellent option for those focused primarily on gorillas, and can be prefaced or extended with time in Ishasha. For a more comprehensive experience that weaves together primates, the tree climbing lions, and Uganda’s broader wildlife, our 15 Days Grand East Africa Safari offers the ultimate itinerary across Uganda and Rwanda. Frena Adventures’ range of East Africa safari holidays can also be tailored to build this kind of dream multi-destination itinerary.

When to Visit and How to Get There

The best time to visit the Ishasha sector for tree climbing lion sightings is during the two dry seasons — June to September and December to February. During these months the grass is shorter, the roads are more manageable, and the lions spend more time in the trees seeking shade and relief from the heat. The dry season also makes game drives through the sector’s remote tracks more accessible by 4WD vehicle.

That said, the lions are present and visible year-round, and the wet season brings its own rewards — lush green landscapes, spectacular birdlife, and a dramatically reduced number of visitors that makes every sighting feel completely private.

Ishasha lies approximately 420 kilometres southwest of Kampala, a scenic road journey of eight to ten hours depending on road conditions and stops along the way. The most popular approach for safari travelers is to fly to Kihihi or Kasese airstrip, both of which are within a comfortable drive of the Ishasha sector, cutting the travel time to under an hour from either strip. From Kigali in Rwanda, Ishasha can be reached in approximately three to four hours by road — making it easily accessible for travelers combining Uganda with a Rwanda gorilla or cultural safari.

Our 11 Days Uganda & Rwanda Cultural Safari includes Queen Elizabeth National Park as a key destination and can be designed to incorporate an Ishasha game drive as part of a seamless, expertly managed cross-border itinerary.

Conservation and the Future of the Ishasha Lions

The tree climbing lions of Ishasha are classified as vulnerable by the IUCN, and their population has faced pressure in recent decades from human-wildlife conflict, habitat loss, and retaliatory poisoning by local herdsmen whose livestock has been attacked. In 2018 alone, 11 lion carcases were discovered in the Ishasha area, their bodies containing insecticide poison left in livestock carcasses by herdsmen in retaliation for attacks on their cattle.

The Wildlife Conservation Society has been operating a dedicated lion monitoring programme in Ishasha since 2005, fitting prides with tracking collars to study their movements and feeding ranges across the Uganda-DRC border. The research has revealed that male lions frequently cross between Uganda and the Democratic Republic of Congo, and that the Maramagambo Forest serves as a crucial migratory corridor connecting the central and southern sectors of Queen Elizabeth National Park.

Conservation efforts continue to focus on mitigating human-lion conflict through community outreach, land clearing outside the park to provide grazing land for herdsmen, and active snare removal within the Ishasha sector. Every safari visit to Ishasha contributes directly to these conservation efforts through park fees that support both the Uganda Wildlife Authority and the communities living on the park’s boundaries.

The tree climbing lions of Ishasha are irreplaceable — an extraordinary wildlife phenomenon found in only one other place on earth, residing in one of Uganda’s most remote and beautiful landscapes. To see them is to witness something that cannot be replicated anywhere else, a reminder of how endlessly surprising and extraordinary the natural world continues to be.
