Greystoke Mahale stands on a white-sand beach along the eastern shore of Lake Tanganyika, deep inside Mahale Mountains National Park in western Tanzania. Six bandas open to the water while rainforest climbs steeply behind them. That forest is home to habituated wild chimpanzees, and guests go to them the old way, tracking on foot directly from camp with no vehicle between them and the trees.
Lake Tanganyika is the second-deepest lake on earth
No roads reach this place. Guests fly in by light aircraft, then transfer by dhow along the lake, arriving at the foot of forest-clad mountains that rise straight from the water. Lake Tanganyika is the second-deepest lake on earth, and on clear days the mountains of the Congo sit low on the far horizon, a pale line between water and sky.
Roland Purcell was an Irish adventurer who had worked on mountain gorilla conservation in Rwanda when he found this stretch of shore in 1988. With his wife Zoe he built a camp from the timbers of old fishing dhows, naming it after Tarzan’s fictional title, Lord Greystoke. He would later co-found the Tongwe Trust to protect the Ntakata Forest, and his idea of a remote camp built around chimpanzees still defines the place.
That long habituation allows close, unhurried observation of grooming
Japanese researchers have studied the chimpanzee community here, the M-group, since the 1960s. That long habituation allows close, unhurried observation of grooming, foraging and shifting social politics, at a regulated distance and for limited time each visit. A trek might be a gentle walk or several steep hours, depending on where the group has wandered that day.
Mornings usually begin with a trek into the hills, guides and park rangers reading the signs of movement until the chimps are found. Afternoons belong to the lake. Guests swim off the beach, snorkel among the cichlids, kayak the shoreline or drift out on the dhow at sunset. Lake Tanganyika holds more than 250 species of cichlid, so the snorkelling rarely disappoints. Fishing is catch-and-release, and forest walks lead to waterfalls and cool rock pools where the day’s heat falls away.
The forest keeps company beyond the chimps. Red colobus share the canopy with red-tailed and blue monkeys, bushbuck and bushpig move through the undergrowth, birdlife runs thick along the shore, and hippos surface offshore. There is no big-game viewing and no vehicle game drives here, for Greystoke sits inside a national park rather than a private conservancy. The rhythm is built around walking and water, closer to expedition travel than a conventional savannah safari, and it rewards those who come for exactly that.
a genuine lake beach with a mountain rainforest and habituated wild chimpanzees
Each banda is open at the front, closed only by heavy canvas curtains, so the lake breeze, the lap of water and the calls of the forest come straight in. That openness will not suit every guest, particularly those who want a fully enclosed, air-conditioned room, and it adds to the effort of getting here: a long flight, then a dhow transfer, then steep forest terrain on the treks themselves. Only two scheduled flights reach Mahale each week, which in practice makes for stays of three to four nights.
Dining keeps to the same unpolished spirit. Fresh food comes to the table in the thatched beach lodge, dinners are laid out privately on the sand by candlelight, and lake fish is prepared as sashimi during sundowners on the dhow. The sunset bar, built from an old boat on a rocky headland, catches the last light over the water. Few places pair a genuine lake beach with a mountain rainforest and habituated wild chimpanzees on the same stretch of shore, and that combination, together with its history under Roland Purcell, has made Greystoke Mahale one of the most distinctive lodges in Tanzania.
01
accommodation
Six open-fronted bandas rise from the beach, built from reclaimed dhow wood and bamboo and roofed with palm thatch. Each stands two storeys tall, a ground-floor bedroom and en-suite bathroom with an al fresco shower giving way to an upper deck for relaxing above the sand. Only heavy canvas curtains close the fronts, drawn for privacy or weather.
02
activities
Chimpanzee trekking on foot is the focus, led by guides and national park rangers, with time at the group limited under park rules. Beyond it, the days run to forest walks that reach waterfalls, to swimming, snorkelling and kayaking on Lake Tanganyika, to catch-and-release fishing, dhow cruises and birdwatching. No vehicle game drives operate inside the park.
03
conservation
The chimpanzees are protected within Mahale Mountains National Park, managed by TANAPA, with all trekking regulated to limit disturbance. Roland Purcell co-founded the Tongwe Trust, which works to protect the Ntakata Forest. The camp supports the neighbouring Katumbi village, including its school and clinic, and sources produce from a local gardening project.
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.
Mahale is among the most remote lodges in Tanzania, and no roads reach it. You fly by light aircraft to a lakeshore airstrip, usually routing from Arusha or the western circuit, then transfer by boat or dhow along Lake Tanganyika to the camp, which sits at the foot of forest-clad mountains rising straight from the water. We build the flights and the boat transfer into one journey and confirm the timings with your dates.
Because the aircraft run on a small western network, seats are shared and the routing is fixed close to the day, and luggage is soft bags only with a limit of around 15 to 20kg. If the shared schedule does not suit your dates, we can arrange a private charter, typically a Cessna Caravan or Pilatus PC-12, flown to your own timings. Mahale pairs naturally with Katavi's game on the same loop, and we will plan the two together so the connections work.
Yes. Although it is called the Mahale Mountains, the camp and its activities sit on the low, hot lakeshore of Lake Tanganyika, well below 1,800 metres, and current UK guidance from TravelHealthPro treats all of mainland Tanzania below that height as a malaria area. The camp provides nets and repellent, but antimalarial tablets and covering up after dark are the real protection.
Health advice can change from year to year, so we always ask you to confirm the current position with a travel clinic or your doctor before you travel, and to take the usual care against bites after dark.
The lakeshore is hot and humid, and the chimpanzee trek climbs steep, sometimes muddy forest, so you are dressing for heat and effort at once.
Pack light, breathable clothes, swimwear for the lake, and sturdy shoes or trainers with grip for the trek, plus a light long-sleeved layer and long trousers for the forest, insect repellent, a hat, sunglasses and sunscreen. A light waterproof is worth having outside the driest months.
This is the reason to come. A community of wild chimpanzees, studied by Japanese researchers since the 1960s, lives in the forest behind the beach, and you go to them on foot, tracking directly from camp with guides and national park rangers and no vehicle between you and the trees. The long habituation allows close, unhurried watching of grooming, foraging and shifting social politics, at a set distance and for a limited time with the group under park rules. There are no vehicle game drives here; between treks the days run to forest walks, swimming, snorkelling and kayaking on the lake.
Come in the dry season from July to October, when the group moves down to the lower slopes near camp, making sightings shorter to reach, drier and more frequent, with August and September the standout. The green season is lush but the chimps climb higher and the trails grow muddy, and the March to May rains close most camps. Because sightings are never guaranteed on a single trek and the journey in is long, we would suggest at least three nights.
It is a remote camp built around a demanding forest trek to see wild chimpanzees, on steep terrain and with park rules on how the group is approached, so it is not suited to young children. Chimpanzee trekking also carries minimum-age rules that we will confirm for your dates.
Tell us the ages of any older children and how they are on foot, and we will say honestly whether it fits.
Barely, and by design. Mahale is one of the most remote places you can stay in Tanzania, so you should not count on wifi, and mobile signal on this stretch of Lake Tanganyika is very limited to non-existent.
It is as close to genuinely off the grid as a safari gets, which is much of the appeal. If you need to stay reachable, tell us before you travel and we will confirm what is currently possible and set expectations.
