🇨🇷 Costa Rica · Northern Lowlands
Sarapiquí is one of the great doors into Costa Rica's humid tropical forest, a land of lowlands, powerful rivers and lush woods in the Northern Lowlands, where the Central Valley drops toward the plains that stretch out to the Caribbean. Crossed by the Sarapiquí and Puerto Viejo rivers, this region is a byword for biodiversity, river adventure and, above all, a long tradition of biological research that made it famous in the world of science.
Here you find some of the most important biological stations in the tropics, such as La Selva (run by the Organization for Tropical Studies) and the Tirimbina reserve, where generations of scientists have studied the rainforest and where travelers can walk among some of the richest flora and fauna on the planet: frogs, snakes, monkeys, sloths, poison dart frogs and an astonishing variety of birds and butterflies.
This guide covers Sarapiquí in practical terms: how to travel the river watching wildlife, where to walk in the forest and visit biological stations, how to take on the adventure of rafting or tubing, and how to make the most of the chocolate and pineapple tours that show the productive life of the area. Because of its position between the Central Valley, the northern volcanoes and the Caribbean, Sarapiquí is a perfect stop for immersing yourself in genuine Costa Rican rainforest.
For centuries, the Sarapiquí region was a land of dense forest and navigable rivers that served as a link between the interior of Costa Rica and the Caribbean coast, by way of the Sarapiquí river and the San Juan river, on the border with Nicaragua. In colonial times and in the 19th century, this river route was strategically important for trade and transport: before the Atlantic railway was built, part of Costa Rica's coffee left for international markets along these rivers. The region was also the scene of episodes of the Campaña Nacional of 1856-1857 against William Walker's filibusters, with fighting tied to the defense of the San Juan river route. Through the 20th century, Sarapiquí was settled as farming and cattle ranching expanded, and the forest gave way to crops, especially bananas and, later, pineapple. Even so, an important part of its nature was preserved thanks to the creation of reserves and biological stations. In 1968 the La Selva Biological Station was established, run by the Organization for Tropical Studies (OET/OTS), which became one of the most important rainforest research centers in the world. With the rise of ecotourism, Sarapiquí established itself as a destination for nature, adventure and scientific tourism, combining conservation with activities such as rafting, chocolate tours and wildlife watching.

Origins, formation and what the sources say.
Long before Sarapiquí was famous for its red-eyed tree frogs and its world-renowned biological stations, its rivers were a highway. Down these powerful waters, boxed in between walls of forest, went the coffee that made Costa Rica rich, bound for the ships of the Caribbean, and along them a war was also fought against an American adventurer who dreamed of conquering Central America. Sarapiquí's story is that of a forest that was at once a strategic trade route, a battlefield, an agricultural frontier and, finally, one of the most important rainforest laboratories on the planet.
The Sarapiquí region, in Costa Rica's Northern Lowlands, was for centuries a territory of dense, warm and humid tropical forest, cut through by powerful rivers such as the Sarapiquí and the Puerto Viejo. These rivers, which eventually flow into the San Juan river —the great waterway of the border with Nicaragua— were far more than geographical features: they made up a route for communication and trade between the country's mountainous interior and the Caribbean coast.
In a colonial and 19th-century Costa Rica with difficult land routes and steep terrain, the Sarapiquí–San Juan water route was strategically important. Before the Atlantic railway existed, part of the country's output —especially the valuable coffee of the Central Valley— could go down these rivers to reach the Caribbean and, from there, international markets. The Sarapiquí forest was thus a corridor between the center of the country and the wider world.
That status as a strategic waterway also explains why the region had military weight. Control of the rivers connecting to the San Juan was key to defending the territory, something that would be dramatically demonstrated in the mid-19th century, during the struggle against the filibusters.
Sarapiquí was the scene of one of the most important episodes in Costa Rican history: the Campaña Nacional of 1856-1857 against the filibusters of the American adventurer William Walker. Walker, leading a group of mercenaries, had seized power in Nicaragua and was threatening to extend his rule over all of Central America, while also seeking control of the interoceanic transit route that ran along the San Juan river.
Precisely because of its strategic value, the region of the San Juan and Sarapiquí rivers became a theater of operations in the war. Costa Rican forces fought to secure control of this waterway and cut the filibusters' supply lines. Command of the river was key to stopping Walker's advance and to the Central American strategy of driving him out for good.
The victory of Costa Rica and the other Central American countries over Walker became a founding milestone of Costa Rican national identity, with heroic figures such as the soldier Juan Santamaría. For Sarapiquí, this story left the mark of having been, for a moment, a nerve center in the defense of national sovereignty, thanks to those rivers connecting the interior of the country with the northern border.
Through the 20th century, the Northern Lowlands and Sarapiquí went through an intense process of agricultural settlement. Road building, the arrival of settlers looking for land and the expansion of the farming frontier transformed the landscape: large areas of tropical forest were felled and turned into pasture for cattle and into plantations of commercial crops.
Bananas played a prominent part in the economy of the northern and Caribbean zone, within the great banana industry that shaped the history of Costa Rica and Central America. Later, in the closing decades of the 20th century and the start of the 21st, pineapple became Sarapiquí's star crop: Costa Rica came to be one of the world's largest pineapple exporters, and the region filled with extensive plantations of the fruit.
This agricultural development brought prosperity and jobs, but also heavy pressure on the ecosystems: deforestation, fragmentation of the forest and environmental challenges linked to monoculture and the use of agrochemicals. The tension between productive use of the land and conservation of nature became a central issue for the region, which, in spite of everything, still holds important pockets of forest thanks to the reserves and biological stations.
Amid the agricultural advance, a significant part of the Sarapiquí forest was saved by science and conservation. The key milestone was the creation, in 1968, of the La Selva Biological Station, which came to be run by the Organization for Tropical Studies (OET in Spanish, OTS in English), an international consortium of universities and institutions devoted to the study of the tropics.
Over time, La Selva became one of the most important and productive rainforest research centers in the world. Its location —in the transition between the lowlands and the foothills of the mountain range, in one of the country's most biodiverse regions— and its long-term protection made it possible to build up decades of scientific data on tropical ecology. Thousands of researchers and students from all over the planet passed through its trails and laboratories, and countless studies on flora, fauna and the workings of the forest came out of it.
La Selva was also the pioneer of a model that would multiply across Sarapiquí: combining conservation, research and, later, ecotourism. Other reserves and centers grew up around it, such as Tirimbina, which added environmental education and nature tourism to the scientific vocation, establishing the region as a benchmark for studying and enjoying Costa Rican tropical forest.
With the rise of nature tourism that turned Costa Rica into a global ecotourism destination, Sarapiquí found a new calling that speaks to its history of forest, science and farming. The region began offering travelers a rich mix of experiences: boat rides on its rivers to watch wildlife, guided walks at biological stations and reserves, rafting and tubing on the Sarapiquí river, and tours showing its productive life, such as the chocolate (cacao) or the pineapple tour.
This tourism development rests largely on the area's natural and scientific heritage. Biological stations like La Selva and reserves like Tirimbina do not only conserve the forest and carry out research; they also teach and receive visitors, tying conservation to a sustainable source of income. Ecotourism thus joined farming as an economic pillar of the region.
Today, Sarapiquí is a destination that brings together several faces of Costa Rica: lush, biodiverse tropical forest, a world-class tradition of scientific research, the reality of a productive farming region and a model of nature tourism that tries to balance use with protection. For travelers, it is one of the best gateways for understanding and experiencing the tropical rainforest, a short distance from the Central Valley, the northern volcanoes and the Caribbean.
