When is the best time?
Peak: 15 Dec – 28 Feb. Mid December to February (dry) and June–August: gorilla families visit the bai on most days to feed on aquatic plants; elephants come mainly at night
Active from 1 Dec to 31 Aug (December to August) in a typical year.
Time of day
The Mbeli platform is manned from first light to dusk; gorillas typically arrive mid-morning to early afternoon; elephants and the bai's night chorus after dark
- Platform hours: sunrise → sunset
- Gorilla visits (typical): 10:00 → 15:00
- Elephants at night: last light → sunrise
What will you hear?
A silverback's chest-beats and a family's contented feeding grunts in the open, from a platform 20 m above one of the Congo Basin's most-watched clearings; elephants splashing at night, sitatunga barking, parrots at dawn, and a rainforest with no engine within a day's walk.
Binoculars?
Binoculars essential. The platform is 20 m up and the gorillas feed 100–300 m out in the bai; binoculars needed, a scope is the norm.
Where to go
- Mbeli Bai – observation platform and Mbeli camp — The research platform on the bai edge; simple stilted huts nearby for visitors, run with the park. Map
- Mondika – research camp — Habituated gorilla groups on the CAR border; very basic tented research base, visits by arrangement. Map
- Bomassa – park headquarters — WCS/park base on the Sangha river; boat and vehicle access from Ouesso. Map
How to go on your own, and what it costs
Eco-guides and park booking are compulsory (park rule). Cheapest legal way: contact the park/WCS office in Brazzaville (+242 05 747 21 21) or Bomassa directly, travel overland to Ouesso by bus and by public pirogue up the Sangha to Bomassa, and stay in the park's own huts rather than booking a fly-in package.
Cost: Park entry, eco-guide and hut fees per day, plus boat transfers; check current prices with the park.
Free or no-guide alternative: No free way to the bai. The Sangha river at Ouesso and the villages along it are public: hornbills, parrots and the river dawn cost nothing from the bank.
Who runs access
- Nouabalé-Ndoki National Park (WCS Congo) – eco-guides, Mbeli and Mondika camps (park authority) — Park-run
Field-recording notes
The park is run by the Government of Congo and WCS through the Nouabalé-Ndoki Foundation, and all visits are booked through the park with eco-guides (rule). The Mbeli platform is a research site: silence on the platform, no playback, and the researchers' distance rules for gorillas apply. Getting there — Brazzaville to Ouesso by road or air, then the Sangha by boat to Bomassa, then a walk — takes days and is the cost. Humidity total, no power at the bai, sweat bees by day. The CAR border is a few kilometres away; check current travel advice.
