Into the Congo Basin: it starts with gorillas

If you asked a room full of travellers where they'd go to see gorillas, chances are the answer would be almost unanimous. Rwanda. Perhaps Uganda.

For good reason, too. Both have become synonymous with gorilla trekking, offering remarkable opportunities to spend time with endangered mountain gorillas in the wild. They've earned their place on countless bucket lists and remain two of Africa's greatest wildlife experiences.

But hidden away in Central Africa is another gorilla destination that doesn't get the same attention. The Republic of the Congo's Odzala-Kokoua National Park is one of Africa's least-visited wildernesses, and Kamba Africa's seven-night Odzala Discovery offers one of the most immersive ways to experience it.

It doesn't have the same profile as Rwanda or Uganda. Instead, it offers something that's becoming increasingly rare: a safari where the rainforest, rather than tourism, sets the pace.

The Congo Basin is the second-largest tropical rainforest on Earth after the Amazon, stretching across six countries and covering more than two million square kilometres. It's one of the last truly intact ecosystems left on the planet, where rivers still serve as highways, forest elephants wander beneath the canopy and western lowland gorillas move almost unnoticed through dense vegetation.

Unlike the open savannahs that many people associate with an African safari, this is a place where the forest decides what you'll see, and when. Towering trees disappear into an endless canopy overhead, while tangled vines twist between their trunks and butterflies drift lazily through the air. The humidity clings to your skin and the forest is never quiet.

Birds call somewhere high above, monkeys crash through the branches and every so often something unseen rustles through the undergrowth. In a place like this, every sound makes you wonder what's just beyond the trees.

The gorillas may be the headline. The Congo Basin is the story.

Odzala-Kokoua National Park

By now, you might be wondering why more people don't visit. Part of the reason is simply perception. The Republic of the Congo is often confused with its much larger neighbour, the Democratic Republic of the Congo, despite the two being separate countries with very different political landscapes.

In reality, reaching Odzala is surprisingly straightforward. Kamba Africa flies guests directly from Brazzaville into the heart of the national park. There are no busy park gates, queues of safari vehicles or dozens of lodges competing for space. Instead, visitor numbers are intentionally limited, allowing the rainforest to remain exactly as it should.

That same philosophy extends to the gorilla trekking itself. Kamba operates just three intimate lodges across Odzala-Kokoua National Park, with Ngaga Lodge the only one dedicated to gorilla trekking. Hidden amongst the trees, its six rooms are tucked discreetly into the forest, where birds and monkeys provide a constant soundtrack from first light until well after dark. It's the perfect base for your first few days in the Congo Basin.

Rwanda and Uganda are home to more than 35 habituated mountain gorilla families between them, allowing thousands of visitors to trek each year. Odzala takes a very different approach. Just three western lowland gorilla groups have been habituated to human presence, and only two are typically visited by guests. The result is an experience where it's entirely possible to spend your morning in the forest without encountering another trekking group.

The mornings begin before sunrise, when experienced trackers head into the forest, reading signs that most visitors would never notice. Fresh nests, broken branches and discarded fruit gradually reveal where the gorillas spent the night, and once they've been located, your guide leads you into the rainforest.

The anticipation builds with every step until, almost without warning, the forest reveals them. A silverback sits calmly watching over his family while youngsters tumble through the undergrowth and mothers quietly feed nearby. For one unforgettable hour, you're simply another observer in their world, sharing a moment with one of our closest relatives before the forest quietly closes in around them once again.

For many travellers, that's where the story ends. In Odzala, it's really just the beginning.

After three nights at Ngaga, the journey continues to Lango Lodge, and it feels like you've arrived somewhere completely different. Hidden amongst the trees and connected by raised wooden walkways, the lodge overlooks Lango Baï, a vast natural forest clearing where wildlife drifts in and out throughout the day. Forest buffalo graze quietly below the deck, African grey parrots chatter overhead and, if you're lucky, forest elephants emerge from the trees to feed before disappearing back into the forest just as quietly as they arrived.

Lango is where you leave vehicles behind. Guided walks take you through the baï itself, wading through shallow water and marshland, often following the same well-worn paths used by elephants. Fresh footprints pressed into the mud, broken branches and tracks weaving through the clearing reveal who's passed through before you, while the feeling that something could emerge from the forest never really leaves.

From Lango, the journey continues to Mboko Lodge, where the Lekoli River takes over. Exploring it by kayak offers yet another perspective on the rainforest. Without the hum of an engine, it's the smaller moments that stay with you. Kingfishers dart low across the water, monkeys move through the canopy overhead and the occasional ripple along the riverbank hints at wildlife coming down to drink.

Most people come to Odzala for the gorillas, and with good reason. Standing just metres away from a family in the wild is every bit as extraordinary as you'd imagine. But after a week here, it's often the rainforest itself that lingers longest in your memory.

The walks through Lango Baï, the silence of the Lekoli River, the sheer scale of the Congo Basin and the feeling of spending seven days in a place that still operates entirely on nature's terms become just as memorable as the gorilla trek itself.

There are easier places to see gorillas, and there are certainly more famous ones. But very few journeys offer such a complete immersion into the world they inhabit. That's what makes Odzala different.
