🇵🇪 Peru · The Amazon (Jungle)
The Parque Nacional del Manu is probably the most biodiverse protected area on the planet and one of Peru's great natural treasures. It covers around 1,716,295 hectares in the regions of Cusco and Madre de Dios, spanning an astonishing gradient that starts in the Andean puna above 4,000 meters, drops through the cloud forests of the eastern Andean slope and ends in Amazonian lowland rainforest. That huge range of ecological zones is what explains its richness, unmatched anywhere in the world.
Its numbers are record-setting: Manu holds thousands of plant species, more than a thousand bird species, hundreds of mammals -including jaguars, pumas, ocelots, giant otters, monkeys and the spectacled bear- and an uncountable number of insects, reptiles and amphibians. It is also the territory of Indigenous peoples such as the Matsigenka, Harakbut and Yine, and of peoples in voluntary isolation such as the Mashco Piro, whose way of life is strictly protected. For all this, UNESCO declared it a Biosphere Reserve in 1977 and a Natural World Heritage Site in 1987.
You don't improvise a visit to Manu: entry to the tourist zones is strictly controlled and only possible with licensed agencies and guides, never on your own. The classic route leaves Cusco by road toward Paucartambo and the ports on the Alto Madre de Dios, then continues by boat along the rivers to the lodges in the reserved zone. Allow several days, bring quick-drying clothes, strong repellent, rain gear, binoculars and a torch, and look into the yellow fever vaccine and prevention of tropical diseases. The park is managed by SERNANP.
The Parque Nacional del Manu was established on 29 May 1973, building on a national reserve declared in 1968, with the aim of conserving exceptional natural and cultural heritage. UNESCO recognized it as a Biosphere Reserve in 1977 and as a Natural World Heritage Site in 1987. Its territory includes a strictly off-limits core zone set aside for peoples in isolation and for conservation alone, a reserved zone where regulated tourism is allowed, and a cultural zone around it.

Origins, formation and what the sources say.
In southeastern Peru, spread across the regions of Cusco and Madre de Dios, Parque Nacional del Manu protects one of the most extraordinary territories on the planet. Its roughly 1,716,295 hectares span an astonishing altitudinal gradient: they start in the Andean puna above 4,000 meters, drop through the cloud forests of the eastern Andean slope and end in lush Amazonian lowland rainforest. That succession of ecological zones within a single space is the key to its unique richness.
Manu's numbers beggar belief. It holds thousands of plant species, more than a thousand bird species -one of the greatest concentrations anywhere in a single place-, hundreds of mammals and an uncountable number of insects, reptiles and amphibians. Jaguars, pumas, ocelots, giant otters, tapirs, spectacled bears and numerous monkey species move through its forests, while flocks of macaws gather at its clay licks at dawn. It is, quite simply, a living laboratory of evolution.
But Manu is not only nature. Its territory is also the ancestral home of Indigenous peoples such as the Matsigenka, Harakbut and Yine, and of peoples in voluntary isolation such as the Mashco Piro, who have chosen to live without contact with mainstream society. For all this natural and cultural heritage, UNESCO recognized it as a Biosphere Reserve in 1977 and as a Natural World Heritage Site in 1987.
Formal protection for Manu has a history going back to the middle of the 20th century. In 1965, at the suggestion of the Peruvian Flavio Bazán and the FAO expert Paul Pierret, a national park was proposed there, and the importance of the place was confirmed by a 1966 report from the British adviser Ian Grimwood. In 1968 the area was declared a national reserve, and finally on 29 May 1973, by supreme decree, Parque Nacional del Manu was officially born.
International recognition came quickly. In 1977 UNESCO declared it a Biosphere Reserve, bringing it into a global network of areas that combine conservation with sustainable development, and in 1987 inscribed it as a Natural World Heritage Site. In 2002 the lower section of the Manu valley, which had temporary reserved-zone status, was annexed permanently, consolidating the park's present extent.
Today Manu is managed by SERNANP and organized into different zones. The core zone is strictly off limits to tourism and research: it is set aside for peoples in voluntary isolation and for conservation alone. The reserved zone, in the lower Manu river basin, is where regulated tourism is allowed through licensed agencies, with its famous cochas and clay licks. And the cultural or buffer zone, around the edges, is home to communities and offers more accessible visiting options.
One of the most delicate and valuable aspects of Manu is the presence of Indigenous peoples in voluntary isolation, such as the Mashco Piro, and in initial contact, such as some Matsigenka groups. These populations have decided to live apart from mainstream society, and their territory inside the core zone is strictly protected. Respecting the restricted areas is not bureaucratic fussiness: it is a matter of survival, since uncontrolled contact can expose them to diseases they have no defenses against and break apart their way of life.
At the same time, communities such as the Matsigenka who live inside the park face the challenge of maintaining their traditional way of life in a changing context. Some take part in ecotourism and forest management initiatives, looking for conservation that is compatible with their wellbeing rather than achieved at their expense.
Despite its maximum protection status, Manu is not free of threats. Pressure from logging, the opening of roads that could bring illegal mining and drug trafficking closer to its borders, and advancing deforestation around it keep conservationists and institutions on alert. That's why visiting the park responsibly, with serious operators and strictly following the rules, is also a way to support the defense of this irreplaceable treasure.
Calling Parque Nacional del Manu the most biodiverse protected area in the world isn't a line from a tourist brochure; it's a conclusion backed by decades of scientific inventories. The key is its geography: within a single continuous territory, the park drops from over 4,000 meters in the Andean puna to around 300 meters in the Amazonian lowlands. That altitudinal gradient of nearly four kilometers creates an unbroken succession of ecosystems -high-altitude grasslands, cloud forests of the eastern Andean slope, montane forest and lowland tropical rainforest- each with its own set of species. Very few places on earth offer such a range of habitats with no barriers between them.
The figures those inventories produce are hard to match. Manu records more than 1,000 bird species -around 10% of all the world's birds in a single park-, more than 200 mammal species, some 130 documented amphibian and reptile species, and a diversity of plants and insects that specialists still haven't finished cataloguing: a single hectare of Manu forest can hold more tree species than an entire temperate country. Add to that thirteen primate species and a community of large vertebrates -jaguar, puma, Amazonian tapir, giant otter, spectacled bear- that few places keep this complete and intact.
That intactness is perhaps the most exceptional thing of all. While across much of the Amazon hunting, deforestation and fragmentation have emptied the forests of their larger wildlife, Manu keeps whole food chains, top predators included. That's why it works as a global scientific benchmark: it's one of the few places where you can still study how a practically unaltered tropical rainforest operates. Grasping that richness also helps explain why the rules for visiting are so strict, and why protecting Manu matters well beyond Peru's borders.
Since 1969, even a year before the park was formally created, the Cocha Cashu Biological Station (EBCC) has been set up in the heart of Manu's core zone to study the tropical rainforest. Over nearly five decades it became one of the most prestigious tropical forest research centers in the world, with more than 750 scientific publications and 36 master's and doctoral theses produced by Peruvian and foreign researchers who studied everything there from monkey behavior to forest regeneration dynamics.
Alongside the science, from the 1980s and more strongly in the decades that followed, Manu became a pioneering ecotourism destination in Peru. Specialist operators developed low-impact lodges inside and around the reserved zone, training local guides -many from Matsigenka communities- and showing that nature tourism could fund conservation without destroying what made it valuable. That model, still in force, requires all tourist entry to be with operators licensed by SERNANP, limiting visitor numbers and the areas that can be reached.
Today Manu combines those two legacies -top-tier scientific research and regulated ecotourism- as the pillars of its long-term conservation, in a balance that remains a reference model for other protected areas in the South American Amazon.
