Why visit Rubondo Island National Park?
Rubondo Island rises from the southwestern waters of Lake Victoria as one of Africa's most unexpected wildlife destinations. Cloaked in equatorial rainforest across roughly 80% of its surface, this remote island national park feels closer to Central Africa than to the open plains most travellers associate with Tanzania. Chimpanzees move through the high canopy, forest elephants leave tracks along shaded forest paths, and giraffe step into sunlit clearings in the island's south, a striking mix owing as much to deliberate conservation decisions made decades ago as to nature itself.
What makes Rubondo genuinely rare is its exclusivity: a single camp operates within the park, and beyond a handful of rangers and researchers, visitors effectively have the entire island to themselves. Days unfold between quiet forest walks beneath towering canopy, boat cruises along undisturbed shoreline, and the chance to track chimpanzees on foot through dense undergrowth. Evenings often bring hippos grazing on camp lawns and fish eagles calling out across calm water.
Africa's largest island national park rewards travellers seeking something beyond the conventional safari circuit: an intimate, atmospheric wilderness where forest and freshwater lake meet in a setting found nowhere else on the continent.
5 Reasons We Love Rubondo Island
Chimpanzee tracking: Follow expert guides through dense rainforest for an intimate encounter with chimpanzees found nowhere else on Lake Victoria.
Total exclusivity: Explore Africa's largest island national park almost alone, sharing this wilderness with only a few rangers and researchers.
Lake cruises: Glide along undisturbed shoreline spotting hippo, elephant, crocodile, otter and vivid kingfishers from the calm water's edge.
Untouched rainforest: Walk beneath dense canopy covering 80% of the island, where chimpanzee, elephant and giraffe share one compact wilderness.
Bush & Beach combo because of convenient logistics for getting to and from your Serengeti safari via direct flights between the respective airstrips.
All You Need to Know About Rubondo Island
Things to Do on Rubondo Island

What Wildlife Can I See on Rubondo Island?
Chimpanzees: Two troops totalling more than 60 individuals live within the forest, the descendants of animals released onto the island decades ago.
Forest elephants: Push through dense undergrowth on tusks evolved smaller than mainland relatives, less likely to snag on vegetation.
Giraffe: Herds graze the open plains in the island's south, stepping from savannah habitat into sunlight beyond the tree line.
Sitatunga: This shy, swamp-dwelling antelope favours the water's edge and shallows, distinct from the more familiar bushbuck.
Hippos and crocodiles: Hippos graze camp lawns after dark, while neighbouring islets host resting crocodile populations sunning on rocks.
Vervet and colobus monkeys: Vervet monkeys and black-and-white colobus chatter and chase through the upper canopy throughout the day.
Where to Stay on Rubondo Island
Rubondo Island Camp is the only accommodation within the national park, making it one of Tanzania's most exclusive safari settings. Besides a handful of park wardens and researchers, guests staying here effectively have the entire island to themselves, a rare privilege by any East African safari standard.
The camp sits in a sheltered cove on the island's eastern shore, where a sandy beach opens onto a grass lawn before giving way to towering equatorial rainforest. Eight thatch-roofed cottages line the treeline, each with a sheltered private veranda facing out across the water. Hippos are known to graze the lawns outside cottages after dark, and nights at camp combine the gentle lapping of Lake Victoria against the shore with the settling sounds of the forest closing in behind.
From Rubondo Island Camp, guests can join guided chimpanzee tracking through dense forest undergrowth, take open-vehicle game drives across hilltops and open southern plains, walk forested trails with an expert guide, or head onto Lake Victoria for boating excursions. The island's grass airstrip receives scheduled flights connecting to Serengeti airstrips, a journey of around 75 minutes delivering guests from dry, dusty savannah into lush rainforest within a single flight, a contrast so complete it can be difficult to believe you remain in the same country.
Rubondo Island Camp closes each year during April and May, when the long rains make conditions across the island impassable.
Wildlife Reintroduction: An Island Rebuilt
Rubondo's forests and plains today are not entirely the product of nature alone. Gazetted first as a game reserve in 1965, the island was established as a sanctuary for wildlife at a time when several species across the region faced mounting pressure from habitat loss. Between 1966 and 1969, conservationist Bernhard Grzimek and the Frankfurt Zoological Society oversaw the release of animals onto the then-uninhabited island, transforming it into a refuge unlike anywhere else in Tanzania.
Seven species were introduced during this period: African bush elephant, giraffe, suni, mantled guereza colobus, and grey parrots confiscated from illegal trade, alongside roan antelope and black rhinoceros, both of which have since become extinct on the island. Elephants, giraffe and colobus monkeys have thrived, becoming defining sights of a Rubondo safari today.
The most remarkable introduction, however, involved chimpanzees, a species with no natural history on the island. Over four cohorts between 1966 and 1969, 17 wild-born chimpanzees arrived from European zoos and circuses, having spent anywhere from three-and-a-half months to nine years in captivity before their release, with no rehabilitation or pre-release training. Genetic research into their descendants has since revealed a striking detail: their ancestry traces to both the West African chimpanzee subspecies (Pan troglodytes verus) and the Central African subspecies (Pan troglodytes troglodytes), with hybrids between the two also present among them. This matters because Tanzania's only native chimpanzees in Gombe Stream and Mahale Mountains National Parks belong to the eastern subspecies, Pan troglodytes schweinfurthii. The Rubondo population is therefore not simply non-native to the island; it belongs to subspecies that have never naturally occurred anywhere in Tanzania, and includes animals of mixed subspecific ancestry.
Remarkably, within a year of release the chimpanzees had learned to forage for wild food and build nests, reverting to fully wild behaviour. From an original 16 founders, the population has grown to roughly 40 individuals according to nest-count estimates, with more recent troop counts describing two groups totalling over 60 chimpanzees tracked through the forest by guides and researchers. It stands as one of the more unusual chapters in African conservation history: a population thriving in an environment their ancestors never inhabited, now central to Rubondo's identity as a safari destination.
