Lake Chamo is one of those gems that take you by surprise in southern Ethiopia. It lies on the floor of the Rift Valley, next to the pleasant town of Arba Minch: a greenish lake ringed by mountains, savannah and Nechisar National Park. But its big draw has a name of its own, and a slightly unsettling one: the 'Crocodile Market', a stretch of shore where some of Africa's largest Nile crocodiles gather to bask on the sandbanks, a scene that seems to belong to another age.
Sailing on Chamo is a small water safari. In a few hours you see giant crocodiles several metres long, groups of hippos snorting and surfacing, and an impressive range of birds: pelicans, cormorants, kingfishers, herons and the majestic African fish eagle. The backdrop is the Rift mountains and, between Chamo and its sister lake Abaya, the green strip of high ground that Ethiopians poetically call the 'Bridge of God'.
This guide takes a practical look at Lake Chamo: how to arrange the boat trip to the Crocodile Market from Arba Minch, what to see in Nechisar National Park, where to find the viewpoint over the two lakes, and how to use Arba Minch as a base and a gateway to the Omo Valley. It includes real prices in Ethiopian birr verified in July 2026, plus tips for enjoying this spectacular wildlife safely and respectfully.
Lake Chamo belongs to the great lake system of the Ethiopian Rift Valley, a fracture in the Earth's crust that runs through the country from north to south and has created a chain of lakes rich in wildlife. Together with neighbouring Lake Abaya and Nechisar National Park, Chamo lies in a region of huge biological and cultural diversity, home to peoples such as the Gamo. Its modern fame comes from its exceptional concentration of Nile crocodiles and from being close to Arba Minch, one of the gateway towns to Ethiopia's deep south. The region's natural and human history is on our history page.

Origins, formation and what the sources say.
To understand Lake Chamo, you have to look at geology on a grand scale. Ethiopia is split by one of the most impressive fractures on the Earth's surface: the Great Rift Valley, the enormous crack where the planet's crust is slowly pulling apart, a process that over millions of years will eventually open a new ocean and tear the Horn of Africa away from the rest of the continent. The Rift crosses Ethiopia from northeast to southwest, and along its course it has created a chain of lakes that dot the valley floor like a necklace of mirrors.
Lake Chamo is one of these Ethiopian Rift lakes, in the southern stretch of the valley. Together with its sister lake, Abaya — its waters reddish from the sediment carried by the rivers — it forms a pair of large lakes separated only by a strip of higher ground. Both lie on the floor of the tectonic depression, flanked by the escarpments and mountains that mark the edges of the Rift, a landscape of wide horizons, volcanoes and faults.
This geology is no minor detail: the Ethiopian Rift is also one of the key regions for the study of human origins — not far away, in the same fracture system, some of the most important hominin fossils in the world were found — and its nutrient-rich lakes became hubs of life and biodiversity. Chamo, with its spectacular wildlife, is a direct child of that great crack, which is still opening today beneath the feet of those who visit it.
Lake Chamo and Lake Abaya are inseparable in the imagination of southern Ethiopia. Lying side by side on the floor of the Rift, they are separated by a strip of raised, vegetation-covered land that local tradition calls, with lovely poetry, the 'Bridge of God': a tongue of land that keeps the two lakes from joining, as if a hand had wanted to keep them apart. From the heights of Arba Minch, the town that looks out between them, the view of the two lakes — greenish Chamo, reddish Abaya — divided by this natural bridge is one of the most celebrated panoramas in the country.
The surroundings are shaped by an abundance of water. The very name Arba Minch means 'forty springs' in Amharic, a reference to the many springs that rise from the ground and feed a lush lowland forest, a rare jungle-like ecosystem of crystal-clear springs right in the middle of the Rift. This wealth of water, together with the warm climate, makes the region an oasis of biodiversity, very different from the arid lowlands or the cold moorlands found elsewhere in Ethiopia.
Since ancient times the lakes have been a source of livelihood for the local people: fishing, water, fertile land along their shores. But Chamo in particular has always lived alongside a fearsome neighbour that made it famous: Nile crocodiles, which found an ideal habitat in its fish-rich waters and multiplied until they formed one of the largest populations in Africa.
If Lake Chamo is famous today throughout Ethiopia and beyond, it is because of its crocodiles. Its warm, fish-rich waters support an exceptional population of Nile crocodiles, including some of the largest specimens in the country, true giants several metres long. A stretch of shoreline where these reptiles gather to bask on the sandbanks was given, with humour and imagination, the name 'Crocodile Market', as if they met there to trade; the name stuck and became the lake's tourist trademark.
But Chamo is much more than crocodiles. Its waters are home to large groups of hippos — another of the lake's big animals — and its shores and shallows are a birdwatcher's paradise: pelicans, cormorants, marabou storks, herons, kingfishers, jacanas and African fish eagles find food and shelter here. The lake is also an important fishing resource for local communities, who catch tilapia, Nile perch and other species, in a sometimes tense balance with the crocodiles that share the same waters.
This wealth of wildlife, combined with the beauty of the Rift landscape, is what turned Chamo into a top natural destination in southern Ethiopia, and what led to part of its surroundings being protected within Nechisar National Park, created to safeguard both the lakes and the savannah wildlife on the strip of land around them.
The Lake Chamo and Arba Minch region is home to several peoples of southern Ethiopia, notably the Gamo, farmers from the neighbouring highlands, traditionally organised into a multitude of small communities and known for their culture of cotton and enset (the 'false banana', a staple food plant of the south, whose trunk and root are used to make a fermented bread called kocho). Among the Gamo, the Dorze subgroup became famous for their extraordinary elongated, curved houses, woven from bamboo and enset leaves, very tall and movable, and for their fine cotton textiles, which are sold all over Ethiopia.
These societies developed their own social and political systems, with assemblies and traditional authorities, and a close relationship with the land, the highland climate and the region's resources. The Arba Minch area, on the border between the Gamo highlands and the Rift floor, was for a long time a crossroads between those worlds: that of the mountain farmers and that of the fishers and herders of the lowlands.
Nechisar National Park, established on the strip between lakes Chamo and Abaya, set out to protect a unique ecosystem: the 'white plains' (nechisar means 'white grass') with their zebras and gazelles, the riverine forest, the hot springs and the lakes themselves. Like many protected areas in Ethiopia, its history has been marked by tension between conservation and human pressure — settlements, livestock, use of resources — a complex conflict between the needs of local communities and the preservation of nature that is still ongoing today.
Today Lake Chamo and Arba Minch hold a prominent place on the tourist map of southern Ethiopia. The town, pleasant and well connected by air to the capital, serves as a base for the lake's wildlife and Nechisar Park, and above all as one of the main gateways to the Omo Valley and the country's deep south. Many travellers heading to meet the peoples of the Omo stop in Arba Minch, taking the chance to go out on a boat on Chamo, see the crocodiles and hippos, take in the viewpoint over the two lakes and visit Dorze before setting off along the southern route.
The nature tourism built around the 'Crocodile Market' has become an important source of income for the area, with boatmen, guides and rangers who make a living showing visitors the lake's wildlife. This sustainable use of a natural attraction — watching the animals without harming them, at a distance and with respect — is potentially an ally of conservation, as it gives economic value to living wildlife.
Like all the lakes of the Ethiopian Rift, however, Chamo faces environmental challenges: fishing pressure, changes in land use across its basin, deforestation, sedimentation and threats to water quality and levels. The conservation of its crocodiles, hippos and birds, and of the Nechisar Park ecosystem, depends on balancing the region's development and the needs of its communities with the protection of an exceptional natural heritage. Lake Chamo remains, on the floor of the great Rift, a powerful reminder of the force of nature in this land where the planet itself is splitting in two.
