Moukalaba-Doudou National Park

Moukalaba-Doudou National Park in southwestern Gabon protects 4,500 square kilometres of equatorial forest and savanna mosaic approximately 700 kilometres southwest of Libreville, holding an estimated 4,700 western lowland gorillas — one of the highest densities of great apes recorded anywhere in Africa — with gorilla trekking tours costing approximately $500 to $1,500 per person for a three-day guided package including transport from Gamba, accommodation at bush camps, and permits. The park is accessed primarily from the coastal town of Gamba and the Doussala research station near the park’s southern boundary, where a gorilla habituation programme run in accordance with IUCN guidelines enables visitors to observe a semi-habituated gorilla family from a distance of seven metres for up to one hour. Moukalaba-Doudou forms part of the network of thirteen national parks created by Gabon in 2002 and is managed by the Agence Nationale des Parcs Nationaux of Gabon.

The park’s landscape combines dense equatorial rainforest with open savanna clearings and a riverine system that includes the Moukalaba and Doudou rivers from which the park takes its name. The forest-savanna mosaic creates an unusually diverse habitat for a central African park, supporting great apes in the forest sections alongside savanna-edge species in the more open areas. The dry season from May to September is considered the best period for gorilla trekking, when forest access is easier and gorilla movements are more predictable as fruiting patterns concentrate animals in particular areas.

Western Lowland Gorilla Trekking at Doussala

The Doussala research and visitor station near the park’s southern boundary is the main access point for gorilla trekking in Moukalaba-Doudou. A gorilla habituation programme has been operating at Doussala for several years, and a resident gorilla family has been habituated to human presence to the point where guided visits can be conducted without causing significant behavioural disruption. IUCN guidelines require visitors to maintain a minimum distance of seven metres from the gorillas, wear face masks to reduce the risk of disease transmission, and limit group sizes to a maximum of six people per visit.

Gorilla trekking in the dense forest around Doussala requires a physically active approach, with walks of one to four hours through forest terrain to locate the habituated group on any given day. Trackers with deep knowledge of the gorilla family’s range and daily patterns lead the search, and once the family is located, the one-hour permitted observation period begins. The western lowland gorilla is the subspecies present in this part of Gabon, distinguishable from the mountain gorilla by its slightly smaller size, shorter hair, and broader skull. Males can weigh over 200 kilograms and the silver saddle of an adult silverback male is visible even in dense forest conditions.

Other Primates and Forest Mammals

Central chimpanzees are present throughout the forest sections of Moukalaba-Doudou and are heard calling frequently in the early morning hours, though sightings of this shy species require patience and guided searching in productive areas. Mandrills, the world’s largest monkey species and among the most visually distinctive primates in Africa, use the forest edge and savanna transition zones, and groups of several hundred animals have been recorded in the park’s more open sections. Mandrill encounters in the wild are relatively rare given the species’ wariness, but the open areas near the Doussala station have produced sightings for visitors spending multiple days in the park.

Forest elephants inhabit the park’s rainforest zones and are present throughout the year, feeding in the forest interior and occasionally emerging to the savanna clearings in the early morning. Forest elephants are smaller and darker than their savanna-dwelling relatives and are highly cryptic in dense forest; evidence of their presence in the form of trails, dung, and uprooted vegetation is typically more readily found than the animals themselves. Hippos inhabit the rivers and larger water bodies within the park, and the riverbank sections near Doussala can produce hippo sightings from guided walks along the water’s edge.

Forest Buffalo and Savanna Wildlife

The savanna sections of Moukalaba-Doudou provide habitat for forest buffalo, the smaller, reddish-brown subspecies of African buffalo adapted to the forest edge environment of central and west Africa. Herd sizes in the savanna clearings typically range from five to thirty animals, and the animals are most visible in the early morning when they graze in the open areas before retreating to forest cover during the heat of the day. Sitatunga antelope inhabit the swampy margins of the park’s waterways, and their long hooves and semi-aquatic habits make them one of the most distinctive antelope species of the Gabonese forests.

Warthog is present in the more open savanna sections and provides some of the most reliable large mammal sightings for visitors at Doussala. Bushbuck uses the forest edge habitat adjacent to the river systems, and is typically seen in the evening at forest clearings. The leopard is present throughout the park but is rarely seen, and its presence is primarily documented through tracks and camera trap data from the Doussala research programme. Common grey mongoose and African civet are among the smaller carnivores recorded in the park’s forest and forest-edge zones.

Birdwatching in Moukalaba-Doudou

The forest and savanna mosaic of Moukalaba-Doudou National Park supports an exceptionally rich bird community, with the Gabon lowland forest zone holding numerous endemic and near-endemic species of high interest to birdwatchers visiting central Africa. African grey parrot is common in the forest and savanna edge zones, and flocks of dozens of birds are sometimes visible in flight over the park. African pied hornbill and black-and-white-casqued hornbill are conspicuous in the forest canopy, and their loud wing beats and calling make them easy to locate.

Hartlaub’s duck inhabits the rivers and forest streams. African finfoot uses the quieter river sections with overhanging vegetation. In the savanna sections, yellow-throated longclaw is a characteristic grassland species, and various sunbird species are active in the flowering vegetation. Long-tailed hawk and African harrier-hawk hunt the forest edge habitats. The bird list for the broader Moukalaba-Doudou area is extensive and has been augmented by research from the Doussala station over many years, making this one of the better-documented birding sites in Gabon despite its remoteness.

The Moukalaba and Doudou Rivers

The Moukalaba River and the Doudou River and their associated gallery forest provide the primary water-based habitats within the park. Boat excursions on the Moukalaba from the Doussala area give access to river sections where hippopotamus pods are resident, waterbirds concentrate along the banks, and the forested river margins can be explored at close range. The rivers also serve as natural corridors for wildlife movement through the park, and their banks are productive for tracking signs of forest elephant, sitatunga, and other riparian species.

The river systems within the park flow through largely undisturbed forest and carry clear, tannin-stained water typical of lowland central African forest rivers. Nile crocodile is present in the larger river sections. Freshwater fish diversity in the Moukalaba basin is high, reflecting the broader ichthyological richness of the Congo basin drainage system to which these rivers connect. Fishing is not permitted within the national park boundaries, helping to maintain the river ecosystem in its natural state.

Getting to Moukalaba-Doudou National Park

The main access route to Moukalaba-Doudou starts with a domestic flight from Libreville to Gamba, a coastal town in the Ogooué-Maritime Province approximately 700 kilometres southwest of the capital. Afrijet and Trans Air Gabon operate scheduled domestic services to Gamba, with flight times of approximately one hour from Libreville. From Gamba, the Doussala research station near the park’s southern boundary is reached by 4WD vehicle in approximately 1.5 to 2 hours on laterite tracks that require a high-clearance vehicle, particularly after rain. The Savannah Camp and Nyanga River Lodge near Doussala can arrange transfers from Gamba airport for guests.

Gabon requires a visa for most nationalities, obtainable in advance from Gabonese embassies or through the e-visa system. The Central African CFA franc (XAF) is the currency. Booking gorilla trekking visits through a Gabon-based tour operator such as Gabon Travel and Tours or through the Agence Nationale des Parcs Nationaux is strongly recommended rather than attempting to organise independently, as logistics, permits, and guide arrangements at Doussala require advance coordination. Most visitors combine Moukalaba-Doudou with Loango National Park, Gabon’s coastal safari park, on a multi-park Gabon itinerary.
