Top Facts About Tree Climbing Lions in Queen Elizabeth National Park Uganda

Facts about tree climbing lions: The tree climbing lions of Queen Elizabeth National Park rank among Africa’s most captivating wildlife spectacles.

While lions are typically ground-dwelling apex predators, the lions in the Ishasha sector of this Ugandan park have developed a remarkable habit of regularly climbing and resting in trees — a behavior rarely observed elsewhere on the continent.

These tree climbing lions Queen Elizabeth National Park draw thousands of safari enthusiasts each year, offering a unique photo opportunity and a fascinating glimpse into animal adaptation.

Often called the Ishasha tree climbing lions, they represent one of only two main populations in Africa with this habitual behavior (the other being in Lake Manyara National Park, Tanzania).

Why Do Lions Climb Trees? Theories Behind the Behavior

Scientists continue to study exactly why the tree climbing lions of Ishasha behave this way. It is considered a learned behavioral adaptation passed down through generations rather than a genetic trait unique to the species.

Common hypotheses include:

• Escape from the Heat: During the hot midday hours, the savannah ground becomes scorching. Elevated branches in fig and acacia trees offer shade, cooler air, and refreshing breezes.
• Avoiding Insects: Tsetse flies, mosquitoes, and ticks thrive on the ground, especially in wetter periods. Climbing provides relief from relentless biting insects.
• Better Vantage Point: From high perches, lions gain a wide view over the plains to spot prey such as Uganda kob, topi, and buffalo without being easily detected.
• Safe Resting and Socializing: Trees offer a peaceful platform away from ground disturbances, hyenas, or rival prides. Lions often lounge, sleep, or even play in the branches after hunts.

Lions typically hunt on the ground and teach their cubs to climb from a young age. Adult males climb less frequently than females and younger lions, but entire prides can sometimes be spotted sharing a single large tree.

Preferred Trees and Climbing Habits

The tree climbing lions show a clear preference for sturdy species that support their weight. The lions in Queen Elizabeth National Park prefer certain tree species for climbing and these include:

• Sycamore fig trees — Large, with broad branches and comfortable platforms.
• Acacia trees — Provide good structure and are scattered across the Ishasha plains.
• Occasionally other species like candelabra euphorbia.

These trees provide both a good climbing structure and a comfortable perch. Lions climb using powerful claws and muscular forelimbs, often ascending several meters high.

They appear remarkably relaxed, draping themselves over branches in seemingly impossible positions. Sightings are most reliable in the late morning through afternoon when the cats seek shade.

Not All Lions Climb Trees

Important fact: Not every lion in Queen Elizabeth National Park climbs trees. The behavior is most pronounced in specific Ishasha prides and is less common (or absent) in other parts of the park or in most African lion populations.

In typical lion societies, tree climbing is rare and usually limited to cubs or fleeing individuals. The Ishasha lions stand out because whole prides routinely use trees as daytime resting spots, making game drives here highly rewarding.

Comparison with Other Tree-Climbing Lions in Africa

While the Ishasha population is the most famous and reliable in Uganda, similar behavior occurs in Lake Manyara National Park in Tanzania. However, sightings there are less predictable and often harder to locate.

Occasional individual tree-climbing lions have been recorded in the Serengeti National Park Tanzania and Kruger National Park South Africa, but these are exceptional cases rather than habitual group behavior.

Queen Elizabeth’s Ishasha sector remains one of the premier destinations worldwide for guaranteed views of this phenomenon.

Best Time to See Tree Climbing Lions in Queen Elizabeth National Park

The optimal period to witness tree climbing lions aligns with the dry seasons:

• June to September (main dry season)
• December to February (short dry season)

During these months, vegetation is shorter, roads are more accessible, and lions are more visible. Midday heat encourages them to climb for shade, increasing chances of spectacular sightings. Early morning and late afternoon game drives also yield excellent results.

The wet seasons (March–May and October–November) bring greener landscapes and more insects, but roads can become muddy and wildlife may disperse.

Conservation Status and Challenges

The tree climbing lions face serious threats despite their popularity. Uganda’s lion numbers have declined sharply over recent decades due to:

• Habitat loss and fragmentation
• Human-wildlife conflict
• Poaching and poisoning incidents (including a notable 2018 case where 11 lions died in Ishasha)
• Prey depletion

Recent studies indicate Queen Elizabeth National Park now supports roughly 40 lions, with ongoing monitoring and conservation efforts focused on protecting these unique prides. Tourism revenue helps fund anti-poaching and community programs, but sustainable tourism practices are essential to ensure the survival of this rare behavior.

Organizations and the Uganda Wildlife Authority work to safeguard the ecosystem, including research into lion behavior and conflict mitigation with local communities.

Where to Find Tree Climbing Lions in Uganda

Tree climbing lions are almost exclusively found in the southern Ishasha sector of Queen Elizabeth National Park. This remote, savannah-rich area features scattered large trees amid open plains, ideal for the lions’ unusual lifestyle.

Ishasha lies in southwestern Uganda, bordering the Democratic Republic of Congo, and forms part of the park’s diverse ecosystems that include the Kazinga Channel, crater lakes, and Maramagambo Forest. While lions exist elsewhere in Queen Elizabeth National Park and other Ugandan parks like Murchison Falls and Kidepo Valley, the tree-climbing habit is a signature feature of the Ishasha prides.

Queen Elizabeth National Park itself hosts around 40 lions as of recent estimates (down from higher numbers in previous decades), with a significant portion exhibiting this behavior in Ishasha. The park’s overall lion population has faced declines, making sightings of these special cats even more precious.

Planning Your Safari to See Tree Climbing Lions

A visit to the Ishasha sector is easily combined with other highlights of Queen Elizabeth National Park, such as:

• Boat cruises on the Kazinga Channel (excellent for hippos, elephants, and birds)
• Game drives in the Kasenyi plains for classic savannah wildlife
• Chimpanzee tracking in the Kyambura Gorge

Many safari operators offer 3–7 day itineraries that include Ishasha for dedicated tree climbing lions viewing. Private 4×4 vehicles with experienced guides maximize sighting opportunities while maintaining respectful distance.
