Koroi opened in July 2025 on Mount Meru’s forested lower slopes, inside Arusha National Park. Colobus monkeys rattle out territorial calls at first light. They leap through the fig and cedar crowns as the mist lifts, while Sykes’ monkeys work the branches beneath them. Nine rooms look onto a seasonally flooded glade where giraffes move through the trees below.
Colobus monkeys rattle out territorial calls at first light.
Walks go out with an armed ranger, the route set each morning by what the forest offers: an hour among the fig trees, or the descent into Ngurdoto Crater, a caldera no vehicle can reach, where buffaloes and elephants graze the floor. Higher up, the Meru Crater hike crosses waterfalls and a dormant ash cone, and the slower hours go to birding, silvery-cheeked hornbills by day, wood owls calling after dark.
Eight tented chalets stand on raised timber platforms above the glade, joined by a single treehouse suite lifted into the canopy. At this altitude the nights turn cold and the forest presses close. Each room has polished wood floors, an en-suite bathroom, mosquito nets, and canvas walls whose sliding flaps open straight onto the trees.

Meals come out of a timber-and-canvas mess pavilion facing the glade, with a lounge and bar behind it and a fire circle outside for the hour before dinner. Dinner sometimes moves to a clearing in the forest, breakfast to a table along the walking routes. Kilimanjaro International Airport is an hour’s drive away, which makes Koroi a workable first or last night in the forest rather than in Arusha town.
The black-and-white colobus monkey, the species that gives the camp its name, remains its most visible resident. Sykes’ monkeys work the canopy below them. The air at this altitude runs cool and damp, with mist sitting in the trees until mid-morning, and the montane forest is dense with mosses, ferns, orchids and strangler figs. Bushbuck and Harvey’s red duiker cross the glade in front of the chalets, and there is no open savanna within sight of camp, only trees in every direction.
Game drives cover ground the walks cannot: the Momella Lakes, the open glades lower on the mountain, zebra and buffalo along the park’s grassland edges. After dark the drives run with spotlights inside the national park, turning up African civets, bush pigs and bushy-tailed mongooses along the forest edge. The cough of a leopard carries in from the trees, more often heard than seen. Canoes go out on the alkaline Momella crater lakes, drifting close to flamingos, a gentler outing that suits families.

Walks follow the conditions of the day rather than a fixed route, with the guiding weighted toward tracking, botany and birds. Back in the chalets hang illustrations of the park’s fungi, insects and plants, commissioned from the artist Sarah Markes. Children are welcome, and interleading chalets and triple-bed configurations can be arranged for families, though guided walks inside the national park carry a minimum age, so younger families tend toward the game drives, the canoes and time spent watching the glade from camp. Visits to nearby Maasai communities fill an afternoon.
Access runs through the Ngongongare or Momella gates and then along a forest track off the main park road. Kilimanjaro International Airport is roughly an hour away by road, Arusha Airport about ninety minutes. Most guests take Koroi at one end of a longer Tanzania trip, a first night in the trees within an hour of landing, or a last night held back before a morning flight. Coffee on the deck at dawn, mist lifting off Meru’s ridges, hornbills crossing overhead: a quiet start to a safari, and a quieter finish.
accommodation
Nine rooms: eight tented chalets on raised timber platforms and one treehouse suite set high in the canopy. Each has polished wood floors, an en-suite bathroom, mosquito nets, a fireplace and a private veranda facing the glade or the forest. Interleading chalets and triple-bed configurations can be arranged for families.
activities
Guided forest walks with an armed national park ranger, ranging from an hour among the fig trees to the Ngurdoto Crater descent and the Meru Crater hike. Day and night game drives run inside Arusha National Park, with canoeing on the Momella Lakes, birding, and visits to nearby Maasai communities.
conservation
Entara, which operates Koroi, hosts a field mentorship for young African wildlife filmmakers and photographers in partnership with the African School of Storytelling, a Tanzanian organisation that trains emerging film-makers to document conservation work and community life. Entara also runs the Entara Mentorship Programme, a one-year internship and on-the-job training scheme set up to put women and members of indigenous communities into skilled positions in an industry that has rarely offered them. Koroi was the first lodge to open in Arusha National Park, and the park and concession fees it pays go to Tanzania National Parks.
Get in touch and let’s start the conversation. An initial consultation helps us understand what you’re looking for, whether that’s specific experiences, luxury touches, or marking a special occasion, and from there we’ll guide you through what’s possible so you can decide if we’re the right fit.
Most guests come from Kilimanjaro International, about an hour away by road, or from Arusha Airport, roughly an hour and a half. A private charter can use Dolly airstrip instead, around forty five minutes from camp.
Because it sits inside Arusha National Park on Mount Meru's lower slopes, the last part of the drive is already in forest. We arrange the transfer with the booking and time it to your international arrival.
Treat it as lower risk, not malaria-free. The camp sits in montane forest on Meru's slopes where the nights are cold, but both the CDC and TravelHealthPro, the UK's official travel health service, draw the Tanzanian line at 1,800 metres, and much of this park lies below it. Tablets are usually recommended.
We are travel planners rather than medical people, so take the decision with a travel clinic or your doctor and check it close to departure. Cover up at dusk in the forest and use repellent regardless.
Yes, all ages are taken and children under five stay free. The treehouse suite is usually the thing children remember.
The catch is that days here are walked rather than driven, and the forest walks go out with an armed national park ranger under park rules that set their own minimum ages. Shorter walks among the fig trees suit most children; the Ngurdoto Crater descent and the Meru crater hike do not. Give us the ages and we will plan the days around what they can actually do.
Cool and often damp, because this is montane forest rather than open plains. Mornings and evenings are genuinely cold, and cloud can sit on the mountain for hours. The long rains come around March to May and the short rains near November.
Bring proper walking boots with grip, a waterproof jacket, and warm layers for the evenings. Neutral colours for the walking, a hat and sun protection for when the cloud lifts, and a torch for the paths between the chalets.
There is complimentary wifi in the mess area only, not in the chalets or the treehouse.
That is deliberate and most guests come to like it. If you need to be reachable, the mess is the place, and a local data package on your phone is a sensible backstop given how close the camp is to Arusha.
