They call it the Amazonian Caribbean, and when you see those beaches of ultra-fine white sand and the emerald water of the Tapajós River, you get why straight away. But Alter do Chão is not the Caribbean: it is pure Amazon, a quiet little village of fishermen and craftspeople on the bank of a river so wide it looks like the sea, where the water is fresh, clear and warm, and where instead of postcard palm trees there is real rainforest leaning in behind every beach. You are in the heart of Pará, on the land of the Borari people, and you feel it in everything: in the food, in the crafts, in the stories the locals tell.
The big secret of Alter do Chão is its river rhythm. During the dry season (roughly August to December) the Tapajós drops several metres and uncovers sandbanks that turn into spectacular beaches: the most famous is the Ilha do Amor, a tongue of sand facing the village that The Guardian once called the loveliest freshwater beach in the world, and that the Corona brand put among the 100 best beaches on the planet. In the high-water season (roughly February to July) the river rises by up to seven metres, the beaches vanish underwater and the landscape changes: up comes the Floresta Encantada, that flooded forest you paddle through by canoe among treetops poking out of the water. No time of year is a bad one, but they are very different experiences.
Beyond the village and its beaches, Alter do Chão is the gateway to a slice of Amazon worth every minute: the Floresta Nacional do Tapajós with its giant trees and rubber-tapper communities, the Lago Verde ringed by rainforest, the meeting of the waters of the Tapajós and the Amazon, viewpoints such as Serra da Piroca, and the riverside and indigenous communities that keep centuries-old knowledge alive. Come with time, with repellent and with a willingness to be on a boat: here you reach almost everything by paddling or sailing, and that journey over the water is often the best part of the outing.
Long before the Portuguese arrived, these banks of the lower Tapajós were already inhabited by the Borari and other peoples of the Tapajós culture, famous for their pottery. The village was formally founded on 6 March 1626 and Jesuit missionaries settled in the region from the mid-17th century, giving it the name Alter do Chão after a town of the same name in Portugal; in 1758 it was raised to the status of a town. In the early 20th century it was on the route of the rubber taken from the region's seringais, and only since the 1990s has it reinvented itself as a tourist destination: the Amazonian Caribbean we know today. The full story is on our history page.

Origins, formation and what the sources say.
There is one detail that surprises anyone arriving for the first time in this little Pará village: a place in the very heart of the Amazon, thousands of kilometres from any coast, carries the name of a town in inland Portugal. And yet the real past of Alter do Chão does not begin with the Portuguese but a great deal earlier, with an indigenous people who left their mark on the pottery, on the landscape and, though hardly anyone setting foot on the Ilha do Amor knows it, on the very phrase çai erê that gave rise to the village's most important festival.
Long before any Portuguese name appeared, the banks of the lower Tapajós River were already inhabited. These lands in the west of what is now Pará were the territory of the Borari people, recognised as one of the original peoples of the Alter do Chão region, with deep ties to the land built up over centuries, above all with the banks of the Tapajós. Historical records describe villages occupying the area long before the district was formally founded.
The region was one of the great centres of what is known as the Tapajós culture, one of the most remarkable in the pre-Columbian Amazon. Its most famous hallmark is the pottery: highly refined pieces, with anthropo-zoomorphic figures (combining human and animal forms) celebrating Amazonian wildlife. That pottery is considered the oldest craft of the Tapajós peoples, and Borari potters keep the tradition alive to this day.
Archaeological evidence of that past (pottery, stone tools) confirms the area's ancient and dense human occupation. When the Europeans arrived, they did not find a void: they found an indigenous world with its own organisation, its knowledge of the river and the forest, and an identity that, for everything that came afterwards, was not erased.
The formal founding of the village is dated 6 March 1626. From the middle of the 17th century, with missionaries active in the region from around 1650, the area went through an intense process of evangelisation and reorganisation of the indigenous population. The Jesuit missions (alongside a Franciscan presence) gathered the Borari and other groups around a mission settlement tied to Catholic worship, and Catholicism became interwoven with local life in a way that persists to this day.
The name Alter do Chão is a direct tribute to a Portuguese town of the same name, Alter do Chão, in the Alentejo region of Portugal. It is a typical case from the colonial period: the Portuguese christened new overseas settlements with the names of towns back home, transplanting a piece of Portuguese geography into the deep Amazon. That is why a little village on the banks of the Tapajós carries a name that sounds so Portuguese.
Administrative growth came in the 18th century: on 6 March 1758, Francisco Xavier de Mendonça Furtado, governor of the State of Grão-Pará e Maranhão in colonial Brazil, raised the village to the status of a town. It was part of the Pombaline reforms that reorganised the administration of the Amazon and turned former missions into civil towns.
In the early 20th century, Alter do Chão was one of the transport routes for the latex tapped from the region's seringueiras (rubber trees), at the height of the Amazonian rubber economy that linked it to nearby hubs such as Belterra and Fordlândia (Henry Ford's projects on the Tapajós). It was, however, a short-lived economic period: when the rubber cycle declined, the region fell off the main routes and entered a long stretch of quiet, close to obscurity, sustained by fishing, subsistence farming and riverside life.
That same isolation, paradoxically, helped preserve the place. While much of the Amazon came under pressure of every kind, Alter do Chão remained a little fishing village with beaches that appeared and vanished to the rhythm of the river. The rubber-tapping legacy was not entirely lost: to this day, in Floresta Nacional do Tapajós communities such as Jamaraquá, descendants of those families keep the latex trade alive.
The big turn came only from the 1990s onwards, when the district began betting on tourism as its economic engine. The beauty of its white-sand beaches and emerald-green water gradually made its name, and the place ended up crowned the Amazonian Caribbean, a comparison that became the destination's trademark. International recognition did the rest: the newspaper The Guardian went so far as to rate the beach on the Ilha do Amor the loveliest freshwater beach in the world, and rankings such as the Beach 100 placed it among the best beaches on the planet.
The identity of Alter do Chão is distilled every September into the Sairé (or Çairé) festival, considered the oldest expression of popular culture in the Amazon and celebrated for more than 300 years. It is a living blend: it combines indigenous traditions of the Borari people, the customs of the riverside peoples and the Catholic religiosity inherited from the missions. In 2024 it was recognised by federal law (Law 14.997/2024) as an expression of Brazilian culture. The 2026 edition is scheduled for 17 to 21 September in Alter do Chão.
The original term çairé comes from the words çai erê, used as a greeting by the Borari, and is usually translated as a Salve! Tu o dizes. The festival's central symbol is the Sairé itself: a decorated semicircular standard, around which turn processions, songs, dances and rituals mixing the sacred and the profane.
Since the 1990s, the festival has taken on a component that made it famous across Brazil: the Festival dos Botos. From 1997 it was folded in as a contest between two folklore associations, the Boto Tucuxi and the Boto Cor-de-Rosa, representing the two species of river dolphin in the Amazon basin. The competition, with floats, music and choreography, rests on one of the Amazon's most powerful legends: that of the river dolphin who on full-moon nights turns into a seductive man, elegant and wearing a hat, who wins the hearts of young riverside women. Myth and spectacle merge in a festival that is today a marker of the village's identity.
Since the mid-2010s, and above all after international media such as The Guardian and rankings such as Corona's Beach 100 put the Ilha do Amor on the global map, Alter do Chão went from a secret shared among backpackers and nature photographers to a destination with mass reach. Santarém airport widened its connections, new pousadas and chef-led restaurants appeared, and the village —which for generations lived off the river, fishing and subsistence farming— had to learn, almost from one year to the next, to live alongside thousands of visitors a season.
That growth brought concrete benefits: local jobs, income for the Floresta Nacional do Tapajós communities that offer community-based tourism, and an international shop window for Borari and riverside culture that had gone all but unnoticed outside Pará. But it also brought the tensions typical of any destination that becomes popular overnight: pressure on basic infrastructure (water, sanitation, waste management), rising prices for residents themselves, and the risk, flagged by environmental organisations and local researchers, that mass tourism ends up eroding exactly what made it attractive: the quiet of the fishing village and the health of its beaches and waters.
The response that has taken shape in recent years combines tourism and conservation more deliberately. The Floresta Nacional do Tapajós, with its seven communities licensed for ecotourism, works as a model of how to keep the forest standing while generating genuine income for the people who live in it, rather than displacing them. The Prefeitura de Santarém promotes guided trilhas —such as the Serra da Piroca one— combining nature with environmental education, and the legal recognition of the Sairé festival in 2024 as national cultural heritage sought, among other things, to shield local identity against the purely commercial logic of beach tourism. The challenge ahead, guides and organisations in the region agree, is holding that balance: going on being the Amazonian Caribbean without ceasing to be, above all, a Tapajós village.
