There are wildlife encounters that leave a gentle mark, and then there is the Congo Basin.

This isn’t a safari in any conventional sense. You won't find vehicle traffic jams, radios crackling with coordinates, or predictable, staged sightings. Instead, this is a journey deep into the world’s second-largest rainforest—an ancient, living ecosystem where forest elephants slip like shadows through misty clearings, western lowland gorillas move through high canopy, and wide, glassy rivers feel almost untouched by time.

The Republic of Congo remains one of Africa's last truly wild frontiers. Remote, ancient, and deeply immersive, it offers a kind of travel that has become extraordinarily rare. For those willing to embrace the unpredictability of the rainforest, the rewards are unlike anywhere else on the continent.

"Congo changes the way you think about wilderness. It feels ancient, untouched, and immersive in a way very few places still do." -  Brett Horley, BHS Safaris

Odzala-Kokoua: The Heartbeat of the Rainforest

At the centre of this experience lies Odzala-Kokoua National Park, one of Africa's oldest protected reserves and one of Central Africa's most important strongholds for biodiversity.

Located in the remote north-western Republic of Congo, Odzala forms part of the vast Congo Basin rainforest. Unlike the open savannahs of East and Southern Africa, this is an intimate landscape where the forest closes around you, sunlight filters through towering trees, and wildlife reveals itself slowly and quietly. Every sighting feels earned.

Although internationally recognised for its population of critically endangered western lowland gorillas, Odzala offers far more than primates. Forest elephants emerge cautiously into mineral-rich clearings, while bongos, sitatungas and forest buffalo move silently through the dense undergrowth.

Lowland Gorillas vs Mountain Gorillas: What’s the Difference?

Western lowland gorilla trekking in Congo is very different from mountain gorilla trekking in Rwanda or Uganda, largely because the species and landscapes are so distinct.

In Odzala-Kokoua National Park, western lowland gorillas live in humid rainforest, forest swamps and baïs. They are slightly smaller and more agile than mountain gorillas, with lighter coats and a distinctive reddish-brown crown. Treks are usually flatter, but can be muddy, warm and densely forested.

Mountain gorillas are found in Rwanda, Uganda and the DRC, mainly in cooler, high-altitude forests on volcanic slopes. They are larger and more muscular, with thick black coats, and trekking often involves steeper hiking through bamboo and montane forest.

Neither experience is better; Congo simply offers a rarer, quieter rainforest encounter with one of Africa’s great apes.

The Ngaga Camp Experience

The habituated gorilla families monitored around Ngaga Camp offer one of the most intimate primate encounters anywhere on Earth.

Mornings begin before sunrise as you step into cool rainforest air filled with birdsong and the sounds of insects waking around you. Expert local trackers lead the way, reading the smallest clues: a freshly snapped branch, discarded fruit, or faint footprints in the mud.

Then, almost without warning, you find them. A dominant silverback resting quietly beneath the canopy. Young gorillas tumbling effortlessly through vines. Mothers watch their families while feeding nearby.

You spend one unforgettable hour with the gorilla family, in line with strict conservation guidelines designed to protect both the animals and their habitat. It is a deeply humbling encounter that passes far too quickly.

Beyond the Gorillas: Deep Rainforest Immersion

A single wildlife encounter does not define an expedition to the Congo Basin. It is about complete immersion in one of Africa's most extraordinary ecosystems.

A single wildlife encounter does not define an expedition to the Congo Basin. It is about complete immersion in one of Africa’s most extraordinary ecosystems, where forest elephants, buffalo, antelope, primates and remarkable birdlife all form part of the experience.

Where You'll Stay

Your journey through Odzala-Kokoua National Park unfolds across three intimate camps, each offering a different perspective on one of Africa's most extraordinary rainforest ecosystems.

Ngaga Camp is the heart of the gorilla trekking experience, nestled deep within the rainforest where habituated western lowland gorilla families are monitored by expert trackers. It is here that most guests spend their mornings searching for gorillas before returning to camp surrounded by nothing but forest.

Further south, Lango Camp offers a completely different perspective. Elevated walkways, baï explorations, forest elephant encounters and guided walks immerse you in the rhythms of the Congo Basin, revealing a side of Africa few travellers ever experience.

Mboko Camp, set beside the Lekoli River, provides a relaxed base for kayaking, birdwatching, forest walks and exploring the waterways that weave through Odzala.

Together, the three camps create a journey that goes far beyond gorilla trekking, showcasing the remarkable diversity of this ancient rainforest.

Gateway & Practical Logistics

Most expeditions begin in Brazzaville, the vibrant capital of the Republic of Congo. Situated on the banks of the mighty Congo River opposite Kinshasa, the city blends French influence, colourful markets and lively river culture.

Recommended Route

Arrive in Brazzaville

Fly into Maya-Maya International Airport (BZV) before overnighting at the Radisson Blu M'Bamou Palace Hotel overlooking the Congo River.

Charter Flight to Odzala

The following morning, board a private scheduled charter flight directly into Odzala-Kokoua National Park, a journey of approximately two hours.

Safety & Peace of Mind

It is important to distinguish the Republic of Congo (Congo-Brazzaville) from its eastern neighbour, the Democratic Republic of Congo (DRC).

Congo-Brazzaville is a peaceful and stable country. Odzala-Kokoua National Park is managed in partnership with African Parks, ensuring exceptional conservation standards, carefully managed logistics and a seamless experience from arrival to departure.

Who Is This Journey For?

This expedition is designed for travellers who value authenticity, conservation and genuine wilderness over conventional safari experiences.

It is best suited to those who enjoy moving at the pace of nature, appreciate wildlife in its purest form, and are willing to trade predictability for discovery. While a reasonable level of fitness is recommended for humid rainforest trekking, the greatest requirements are patience, curiosity, and an adventurous spirit.
