The Lésio-Louna Gorilla Nature Reserve is one of the most exciting and accessible experiences the Republic of the Congo has to offer: a sanctuary in the heart of the Batéké Plateaux, north of Brazzaville, where western lowland gorillas orphaned or rescued from the illegal trade in infant apes are rehabilitated. Run by the Aspinall Foundation, a British conservation organisation, the sanctuary raises the young gorillas, cares for them for years and gradually returns them to the wild, in pioneering work to protect this threatened species.
The landscape surprises anyone expecting dense jungle: here, the Batéké Plateaux are a world of rolling savannah, dry forest and gallery forest following the rivers, with the stunning, crystal-clear Lac Bleu as one of their gems. Getting to the gorillas is part of the appeal: you travel by boat along the river, cross the plateaux and arrive at Iboubikro camp, home to the baby gorilla nursery. It's also the only trip that lets you get close to gorillas without heading into the remote parks of the north.
This guide explains how to arrange the visit from Brazzaville: how to get there, what you'll see at the sanctuary, how visits to the 'nursery' and the adults work, where to stay and what health precautions to take so you don't put the gorillas at risk. Lésio-Louna combines nature, adventure and a moving conservation story, and it's one of the big reasons to visit this little-known corner of Africa.
The Lésio-Louna Reserve was created in 1999 through a partnership between the Government of the Republic of the Congo and the UK's Aspinall Foundation, with the aim of rehabilitating and reintroducing orphaned western lowland gorillas, mainly infants rescued from the illegal bushmeat trade. The foundation has been working in the Batéké Plateaux region since the late 1980s and has returned dozens of gorillas to the wild. The sanctuary, linked to the neighbouring Léfini reserve, has become a model for conservation in Central Africa. Its story is told on our history page.

Origins, formation and what the sources say.
The Lésio-Louna sanctuary sits on the Batéké Plateaux (Plateaux Batéké), one of the most distinctive natural regions of the Republic of the Congo. Unlike the stereotypical image of equatorial rainforest, the landscape here is one of wide, rolling savannahs on sandy soils, dotted with dry woodland and crossed by rivers lined with dense gallery forest. The plateaux rise to between 550 and 830 metres and stretch north along the Congo River into present-day Gabon, forming a transitional ecosystem between forest and savannah.
These lands are the historical territory of the Téké (Batéké) people, who gave them their name. The Téké, farmers and hunters, lived on these plateaux long before the Europeans arrived, with their own kingdom and their own king, the Makoko. It was with a Téké Makoko that Pierre Savorgnan de Brazza signed the 1880 treaty that led to the founding of Brazzaville. Because they were relatively remote and sparsely populated, the plateaux kept large natural areas intact for a long time.
In more recent times, this landscape of savannah and gallery forest proved ideal for wildlife conservation projects. The mix of rivers, forest and open ground, together with low human pressure in some areas, made the Batéké Plateaux a suitable place to create reserves and sanctuaries to protect and reintroduce threatened species, among them the western lowland gorilla.
Nature protection in this region has deep roots. The neighbouring Léfini Faunal Reserve (Réserve de Faune de la Léfini), created in the colonial era (in the mid-20th century), is one of the oldest protected areas in the country and covers a vast expanse of savannah and gallery forest on the Batéké Plateaux, north of Brazzaville. For decades it was the area's great wildlife refuge, home to buffalo, antelope, hippos, many species of monkey and, at one time, gorilla populations.
The Lésio-Louna Reserve grew out of this conservation tradition and is geographically linked to the Léfini: it takes in the southern part of what was the Léfini faunal reserve, and in a way it continues and renews it. Together the two areas form a single block protecting the biodiversity of the plateaux, recognised internationally as a key area for conservation.
On this historical foundation, a specific and pioneering project was launched at the end of the 20th century: a sanctuary devoted to rehabilitating western lowland gorillas and returning them to the wild. The western lowland gorilla is one of the most iconic and threatened species in Central Africa, and this project is what would make Lésio-Louna internationally known.
The modern history of the sanctuary is tied to The Aspinall Foundation, a British conservation organisation that has worked in the region since the late 1980s. Faced with the illegal trade in baby gorillas, a result of adults being poached for the bushmeat trade and their young left orphaned, the foundation set up a programme to rescue and raise these animals and reintroduce them to the wild, both in the Congo and in neighbouring Gabon.
In 1999, The Aspinall Foundation and the Government of the Republic of the Congo formally established the Lésio-Louna Gorilla Reserve, covering some 173.000 hectares and jointly managed by the foundation and the Ministry of Forest Economy. The sanctuary became the heart of the 'Gorilla Protection Project'. Orphaned infants are raised here in the 'nursery' and socialised, then prepared in successive stages to live in the wild again. These stages include river islands where they gain independence.
Over the years, the project has reintroduced dozens of gorillas to the wild, a remarkable achievement in a field as difficult as great ape reintroduction. The work combines veterinary care and hand-rearing with habitat protection and anti-poaching efforts, and it has made Lésio-Louna a benchmark for gorilla conservation in Central Africa.
The star of the sanctuary is the western lowland gorilla (Gorilla gorilla gorilla). It is the most numerous gorilla subspecies, yet it is still classed as critically endangered. It lives in the forests of Central Africa (Congo, Gabon, Cameroon, Equatorial Guinea and the Central African Republic) and its main threats are poaching, the bushmeat trade, habitat loss and diseases such as Ebola, which has wiped out entire populations. The Republic of the Congo is home to some of the largest remaining populations of this subspecies.
Gorillas are social, intelligent animals with complex behaviour. They live in family groups led by an adult 'silverback' male. Their close genetic similarity to humans (they share more than 98 % of our DNA) makes them fascinating, but it also leaves them extremely vulnerable to human diseases. That is why visits are subject to strict health rules.
Lésio-Louna's work is part of the international effort to save this species. Every infant rescued and reintroduced, every gorilla that goes back to living in the forest, is a small victory in a hard battle. The sanctuary also helps raise visitors' awareness of the threat facing great apes and of why it matters to protect the forests and savannahs of Central Africa.
Today the Lésio-Louna Reserve combines its conservation mission with careful, small-scale tourism. It is one of the most popular excursions among the few travellers who make it to the Republic of the Congo. Above all, it is the best chance to get close to gorillas without heading into the remote parks of the north. Visits are limited and organised, and the income they bring in helps fund the protection of the sanctuary and benefits local communities, who are involved in conservation.
Iboubikro camp, reached by road and dirt track, is the base for visitors: it is home to the infants' 'nursery' and the accommodation. From there, boat trips are organised on the Louna and Lésio rivers, along with sightings of the reintroduced gorillas and visits to spots such as Lac Bleu. Everything follows strict health and behaviour rules to protect the animals.
So Lésio-Louna is much more than a tourist attraction. It is a living conservation project in the heart of the Batéké Plateaux, where the story of orphaned infants returning to the wild is woven into the quiet beauty of the savannah, the rivers and the lakes. For the traveller, it is a moving and meaningful experience; for the gorillas, a second chance.
