Queen Elizabeth National Park: tree-climbing lions and the Kazinga Channel explained

Queen Elizabeth National Park is Uganda’s most visited national park and its most ecologically diverse protected area — a landscape where savannah, forest, wetland, and volcanic crater lakes exist within a single park, where the Kazinga Channel’s 40-kilometre waterway between Lake Edward and Lake George supports one of Africa’s densest hippopotamus concentrations, and where the lions of the Ishasha sector in the south have developed the unusual habit of resting in fig trees — a behaviour documented in only a handful of lion populations globally and one that makes QENP a must-visit addition to any Uganda gorilla safari. Queen Elizabeth sits between Kibale Forest and Bwindi on the main western Uganda circuit, making it a natural route inclusion for Uganda safari packages that include Bwindi gorilla trekking.

Queen Elizabeth National Park is Uganda’s most visited national park and the country’s most ecologically diverse protected area, encompassing savannah, forest, wetland, and volcanic crater lake habitats within a single protected landscape. For visitors combining a gorilla trek at Bwindi with a broader Uganda safari, Queen Elizabeth serves as the natural halfway point — geographically positioned between Kampala and Bwindi on the most common road route, and ecologically positioned as a perfect complement to the forest-focused gorilla experience. Its two most celebrated features — tree-climbing lions and the Kazinga Channel boat cruise — are genuinely extraordinary and consistently deliver wildlife encounters that rival anything available at more famous African safari destinations.

Tree-climbing lions: why they do it and where to find them

Lions are generally ground-dwelling predators, and tree-climbing behaviour in lions is rare enough worldwide that it is considered a distinctive and unusual adaptation rather than a normal part of lion ecology. In Uganda’s Queen Elizabeth National Park, however, the lion prides of the Ishasha sector in the south of the park have developed a consistent tree-climbing habit that has been documented for decades and remains one of the most distinctive wildlife viewing experiences in East Africa. Groups of lions are regularly observed resting in the broad horizontal branches of large fig trees, sometimes with multiple individuals distributed through a single tree’s canopy, in a behaviour that is theoretically explained by avoidance of ground-level insects, improved air circulation in the tree, a better vantage point for detecting prey, and social tradition transmitted from adults to cubs within specific family groups.

The Ishasha sector’s tree-climbing lions are most reliably found in the fig tree areas along the Ntungwe River in the southwest of the park. Game drives in this area during the early morning and late afternoon, when lions are most active, produce the highest probability of tree sightings, though lions can be found in trees at any time of day. Sightings are not guaranteed — lions that have been in trees all morning may descend to feed or move before a visitor’s drive reaches them — but the sector’s specific geography and the habituation of its lion prides to vehicle presence make Ishasha one of the most reliably productive tree-climbing lion locations anywhere.

The evolutionary and ecological question of why Ishasha’s lions climb trees while lions in adjacent and similar habitats do not is genuinely unresolved. The most widely cited explanation — insect avoidance, since ground-level flies and other biting insects are more dense in the valley grasslands than in tree canopies — has logical appeal but has not been rigorously tested. The social tradition hypothesis, which proposes that cub observation of adult tree-climbing behaviour produces a learned habit transmitted across generations within specific prides, is consistent with the geographic specificity of the behaviour but requires long-term social data to test properly. For visitors, the mystery of why these lions behave as they do adds intellectual engagement to a visual spectacle that would be compelling regardless of its explanation.

The Kazinga Channel boat cruise

The Kazinga Channel connects Lake George to Lake Edward and runs for approximately 32 kilometres through the heart of Queen Elizabeth National Park. The two- to three-hour afternoon boat cruise on the channel is consistently described by visitors as one of Uganda’s finest wildlife experiences, combining hippo pods, large crocodiles, massive buffalo herds drinking at the bank, and a waterbird diversity that includes more than forty species in a typical cruise. The proximity to animals made possible by the slow boat approach — significantly closer than most game drive encounters permit — and the lateral viewing angle that water level provides produce photographic opportunities that land-based game viewing cannot replicate.

Hippo densities in the Kazinga Channel are among the highest in Africa, with estimates suggesting that the channel and its immediate vicinity support 3,000 to 5,000 hippos. Pods of twenty to fifty individuals are commonly seen from the boat, with the characteristic snorting, head-shaking, and occasional yawning displays that communicate social status and territorial boundaries providing continuous behavioural interest throughout the cruise. The underwater social life of hippo pods, with much of the social interaction occurring below the waterline where boat passengers cannot observe it, adds a layer of hidden complexity to what appears from above as occasional surface activity.

The waterbird diversity along the Kazinga Channel includes the African fish eagle, whose calling is among the most evocative sounds in Africa and is almost always heard during the cruise. Goliath herons stand motionless in the shallows, their enormous size apparent against the shorter vegetation of the bank. Pied kingfishers hover over the water surface, their rapid wing beats holding them stationary against the current before plunging to take small fish. Yellow-billed storks and sacred ibis feed in groups at the water’s edge. The concentration and diversity of waterbirds along the channel makes the Kazinga cruise an essential birding experience as well as a large mammal viewing opportunity, and serious birders often extend their cruise time or arrange additional early morning cruises to maximise their species count.

Other wildlife in Queen Elizabeth National Park

Beyond the tree-climbing lions and Kazinga Channel, Queen Elizabeth National Park offers extensive savannah game viewing that regularly produces elephant, buffalo, Uganda kob, waterbuck, warthog, and various mongoose and small carnivore species. The park’s elephant population, estimated at over 2,500 individuals, is one of Uganda’s largest and most accessible, with bulls and family groups regularly encountered on the main game drive circuits. The interaction between large herbivore populations, the park’s productive grasslands, and the water resources of the two lakes produces ecological dynamics that game drive observation reveals over time in ways that brief visits cannot fully capture.

The Maramagambo Forest, which occupies the eastern portion of Queen Elizabeth National Park, is a separate forest ecosystem from Bwindi but provides habitat for chimpanzees, red-tailed monkeys, and forest birds that complement the open savannah wildlife of the Mweya peninsula game circuits. Day walks into the Maramagambo Forest can be arranged through the park and provide an introduction to tropical forest wildlife that serves as either preparation for or complement to the Bwindi gorilla experience, depending on itinerary sequencing.

Logistics: where Queen Elizabeth fits in a Uganda itinerary

Most standard Uganda gorilla trekking itineraries route visitors through Queen Elizabeth National Park in one direction of the Kampala-Bwindi journey, with visitors spending two to three nights at the park to take a game drive, Kazinga Channel cruise, and, for those visiting the southern Ishasha sector, a tree-climbing lion game drive. The park headquarters and main lodge concentration at Mweya is approximately four to five hours’ drive from Kampala and four to five hours from Bwindi, making it a natural midpoint that absorbs a full day’s driving in each direction within productive wildlife activity.

The Ishasha sector, where tree-climbing lions are found, is approximately two hours south of the Mweya headquarters and is accessed on the road between Kampala and Bwindi via Kihihi. Visitors who route their itinerary through Ishasha rather than through the Mweya headquarters add the tree-climbing lion experience without significantly extending total journey time, though they may sacrifice some of the other Mweya-based activities including the Kazinga Channel cruise. Combining both Mweya and Ishasha in a single Queen Elizabeth visit requires at least two nights at the park, spending the first at Mweya for the cruise and one sector’s game drives, and the second at Ishasha for the tree-climbing lion circuit.

For visitors constrained to a shorter Uganda itinerary, the choice between Mweya/Kazinga Channel and Ishasha/tree-climbing lions is the central Queen Elizabeth planning decision. The Kazinga Channel cruise is almost universally described as outstanding regardless of visitor type, while tree-climbing lion sightings are more variable and depend on lion location on the specific day of the visit. Visitors who are primarily interested in the most reliable wildlife spectacle would typically prioritise the Kazinga cruise; those with specific interest in lion behaviour or photography would prioritise Ishasha. The ideal itinerary includes both, and the extra night this requires is consistently described by visitors as one of the best travel investments they made in Uganda.
