🇨🇴 Colombia · Amazon
The department of Amazonas is Colombia at its wildest and most remote: an immense stretch of tropical rainforest at the country's southern tip, where the roads simply stop and everything revolves around the Amazon river and its tributaries. Its capital, Leticia, is the gateway to the region and a unique point on the continent: the triple border where Colombia meets Brazil (Tabatinga) and Peru (Santa Rosa island), separated by little more than the river.
Visiting the Colombian Amazon means stepping into one of the most biodiverse ecosystems on the planet: pink and grey river dolphins, monkeys, sloths, caimans, thousands of bird species, giant trees and the legendary giant water lily. It's also an encounter with the living culture of the Amazonian indigenous peoples —Ticuna, Yagua, Cocama, Huitoto—, holders of a profound knowledge of the forest, and with destinations such as Puerto Nariño, Lake Tarapoto and Amacayacu National Park.
This guide covers the essentials of Amazonas with a practical eye: how Leticia works as a base, what to see and do (jungle hikes, boat trips, wildlife watching, indigenous communities, the triple border), the best season depending on the river level, real prices, how to get there (only by plane or by river), where to sleep and eat, and health and safety advice for enjoying the rainforest with respect.
The department of Amazonas and its capital, Leticia, have been Amazonian indigenous territory since time immemorial, home to peoples such as the Ticuna, Yagua, Cocama and Huitoto. Leticia was founded on 25 April 1867 by the Peruvian captain Benigno Bustamante and passed to Colombia after the Salomón-Lozano Treaty (signed in 1922 and ratified in 1927), which gave the country access to the Amazon river through the Amazon Trapeze. That border triggered the Colombia-Peru conflict of 1932-1933 (the 'Leticia Incident'), when a group of Peruvians from Loreto seized the town on 1 September 1932; resolved through the mediation of the League of Nations, Leticia was placed under international administration in 1933 and returned definitively to Colombia in 1934. Today Amazonas is the country's great region of rainforest and ecotourism, right on the triple border with Brazil and Peru. The full history is on our history page.

Origins, formation and what the sources say.
Long before any border or town existed, the territory of today's department of Amazonas was —and still is— home to numerous indigenous peoples who have inhabited the rainforest since time immemorial. Among them are the Ticuna (the most numerous people in the region), the Yagua, the Cocama and the Huitoto, along with many other groups scattered across the Amazon Trapeze and the basin of the great river.
These peoples developed a deep and sophisticated knowledge of the forest: of its medicinal and edible plants, of the river's cycles, of the wildlife and of the ways of living in one of the most exuberant and demanding ecosystems on the planet. Their life is organized around the Amazon river and its tributaries, sustained by fishing, hunting, gathering and chagra farming (cleared garden plots), and shaped by a rich worldview expressed in myths, dances, crafts and rituals.
The arrival of Europeans in the Amazon from the 16th century onward, and later the successive waves of extraction, brought disease, displacement and violence that struck these populations hard. Despite everything, the indigenous peoples of Amazonas held on to much of their culture and their territory, and today they are central to the life of the region and an essential part of any respectful travel experience in the rainforest.
In the late 19th and early 20th centuries, the Amazon lived through the rubber boom, which violently transformed the region. Global demand for rubber turned the forest into a stage for extractive exploitation, and the Putumayo and Caquetá area —part of the Colombian-Peruvian Amazon— became the setting for one of the darkest episodes in the history of the Americas.
The company of Julio César Arana, the Peruvian Amazon Company (known as 'Casa Arana'), subjected the indigenous peoples of the region —especially the Huitoto and other groups— to a regime of forced labor, debt bondage and extreme cruelty in the extraction of rubber. International denunciations, above all the report by the diplomat Roger Casement, brought to light a genocide that decimated the area's indigenous populations in the early 20th century.
This period left a deep wound in the Amazon and in its peoples, and at the same time tied the region to the economic and territorial disputes between the Amazonian countries. Control of the forest's riches and of the river routes —in particular access to the great Amazon river— became a strategic matter that, a few decades later, would sit at the heart of the border conflict between Colombia and Peru.
Colombia's access to the Amazon river —and with it the existence of today's department as we know it— is the fruit of a diplomatic agreement: the Salomón-Lozano Treaty, signed between Colombia and Peru in 1922 and ratified in 1927. Under this treaty, Peru ceded to Colombia the town of Leticia and a strip of territory known as the Amazon Trapeze, a wedge running down to the Amazon river that guarantees Colombia a sovereign outlet onto the great waterway.
Leticia, founded on 25 April 1867 by the Peruvian captain Benigno Bustamante, had until then been a Peruvian settlement. With the treaty it passed into Colombian hands, completely redrawing the political geography of the country's south: Colombia, which was essentially Andean and Caribbean, also became an Amazonian country with a river port on the Amazon.
The agreement, however, was poorly received by much of the local Peruvian population, who resisted coming under Colombian sovereignty. That discontent, combined with the difficulty of fixing borders in a remote and thinly populated rainforest, sowed the seeds of a conflict that would erupt a few years later and put Leticia at the center of international attention.
On 1 September 1932, a group of Peruvian civilians —traders and residents of the Loreto region, with the indirect backing of local authorities— occupied the town of Leticia without firing a single shot, in protest at the cession of the territory to Colombia. So began the 'Leticia Incident', which triggered the Colombia-Peru war of 1932-1933, the last armed conflict between the two countries.
The war was fought deep in the Amazon rainforest, under extreme conditions: dense vegetation, the climate, tropical diseases and vast distances made river and air logistics the decisive factor. Colombia organized a military expedition upriver to recover the territory, and clashes took place at various points in the Trapeze and neighboring areas, such as Tarapacá. It was an atypical war, defined by geography more than by great battles.
The resolution came through diplomacy. With the mediation of the League of Nations (the forerunner of the UN), an agreement was reached: Leticia was placed under the temporary administration of the international organization while a definitive solution was negotiated. Finally, in May 1934, after months of tension, Leticia was officially returned to Colombia, confirming what the Salomón-Lozano Treaty had established. That episode consolidated Colombia's presence in the Amazon and also had significant domestic effects, such as spurring the country's modernization and industrialization.
Once the conflict was settled, Leticia and the Amazon Trapeze consolidated as Colombian territory and, over time, as the department of Amazonas, the country's largest and most heavily forested. For decades it was a remote and little-known region; in recent ones it has become one of Colombia's great nature and ecotourism destinations.
The singularity of the triple border —where Leticia (Colombia) physically merges with Tabatinga (Brazil) and looks across the river to Santa Rosa island (Peru)— makes the region a unique place of intense cultural and commercial mixing between the three countries. The Amazon river, gigantic and ever-present, is the axis of life: people travel, trade and live along it. The river's own shifting geography keeps the border question alive: between 2024 and 2025, the sovereignty of Santa Rosa island (which Peru administers and considers part of the old Chinería island, assigned in 1929) once again strained relations between Lima and Bogotá, a distant echo of that old conflict of the 1930s.
Today Amazonas combines the conservation of extraordinary biodiversity —with protected areas such as Amacayacu National Park—, the life of the indigenous peoples, and a growing ecotourism industry offering jungle hikes, pink dolphin watching on Lake Tarapoto, community visits, lodges and the experience of Puerto Nariño as a model sustainable village. The great challenge remains balancing tourism development with the protection of the rainforest and respect for its original inhabitants, in one of the most valuable regions on the planet.
