The Northern Plains span an extensive territory that includes Poás Volcano National Park on the Caribbean slope and sidling over to Juan Castro Blanco National Park near Zarcero. To the north, the region’s boundaries cross the Tilarán Volcanic Mountain Range and to the south slide over the Guanacaste Mountain Range and the area surrounding Tenorio Volcano. The plains pass between the ancient volcanic cone and end at the towering Miravalles Volcano.

The Northern Plains area is such that it also covers the area north of Miravalles Volcano and Rincón de la Vieja Volcano, jutting out north towards Costa Rica’s plains bordering Nicaragua. The region borders the towns of Upala, Caño Negro, and Los Chiles to the north and also includes the road that connects Los Chiles with the canton (similar to a county) of San Carlos. Finally, it stretches down toward the Infiernito River, where it turns east toward the San Carlos River.

From the San Carlos River mouth, the Northern Plains venture south to the Cuarto de Grecia River, where the region continues toward the canton of Sarapiquí, which borders both the road between La Virgen and Horquetas as well as the Sarapiquí River, Here, it continues to the northern section of Braulio Carrillo National Park and the Central Volcanic Mountain Range at its eastern limit between Poás National Park and Juan Castro Blanco National Park.

Dominion over Nature

In the Northern Plains region of Costa Rica, tourists may choose between a wide range of activities. For example, horseback rides, hikes along trails or paths, ATV tours, boat trips, bird and wildlife watching, waterfall visits, river rafting, and picnics by lagoons, as well as visit to national parks, protected areas, and volcanoes are all popular.

The Northern Plains are known for consistent rainfall, and the region’s habitats include tropical wet forests, which are home to year-round warm weather. Fertile plains cover the area and serve as true sanctuaries for all kinds of animal life, including aquatic birds, reptiles and mammals. Among these, the prehistoric gaspar fish stands out as one of the region’s most unique inhabitants.

The gaspar, or crocodile fish as its also known, is a primitive species that lived during prehistoric times. Due to its ancient origins, this fish is an important element in one of the world’s most unique ecosystems. The first record of the gaspar fish’s ancestors correspond to fossils from the Cretaceous Period (between 80 and 90 million years ago), earning this species its nickname as a living fossil. Another distinctive quality of the gaspar fish is that it shares the characteristics of both fish and other reptile species.

These unique tourism opportunities make the Northern Planes a very special destination for wildlife lovers and nature photographers.


Home to natural landscapes including those already described, the Northern Plains are a veritable hotspot for tourists seeking excellent opportunities for nature photography. Capturing the moment in just one small click applies not only to the region’s diverse flora and fauna, but also to the beautiful scenery, the Costa Rican people, regional culture, and this area’s way of life.
Boat Tours
Since the Northern Plains see year-round rainfall, there region’s waterways stay full, creating many options for taking day trips in boat. River tours, lagoon floats, and canal explorations are a popular and exciting way to observe the region’s diverse wildlife and nature offerings.
Observation of Flora and Fauna, Including Birds and Butterflies
One of the region’s main attractions is staying overnight at lodges located in national parks and protected areas. Here, visitors will enjoy a variety of enriching and enjoyable activities. National parks in the region include Arenal, Juan Castro Blanco, Caño Negro Wildlife Refuge, and Bosque Alegre Wildlife Refuge.

Natural Hiking Trails, Hanging Bridges, and Canopy Tours
Throughout the region’s vast territory, several tour operators and companies dedicated to recreational pursuits have developed facilities with the sole purpose of creating new ways to enjoy nature and dive into adventure including hanging bridges, naturalist hiking trails, and zip-line canopy tours.

A handful of tourism companies are scattered throughout the towns of the Northern Plains, specifically La Fortuna (Arenal), La Virgen de Sarapiquí, and Puerto Viejo de Sarapiquí.

Protected Areas

Caño Negro Wildlife Refuge
Caño Negro is a tropical wet habitat that, thanks to its wetlands, is considered of great importance on a global level. The refuge’s wetlands are of vital importance to the environmental stability of Costa Rica’s northern region. Its various habitats are home to a wide variety of flora and fauna, many of which are endemic to the Northern Plains or in danger of extinction. Among these species are aquatic birds like jabirus and species of reptiles including caimans and turtles.

During the dry season (December-April), this refuge is responsible for a vital environmental function: becoming a food supply for thousands of migratory aquatic birds that seek shelter in the reserve’s wetlands. Each year, the plumage of several resident bird species takes on a rosy hue, due to the animals’ ingestion of certain local mollusks.

Given its natural diversity, Caño Negro is home to a host of plant and animal species that are not found in other parts of the country, among them the gaspar fish. Due to its prehistoric origins, this fish is often called a living fossil.

This large and biodiverse region also gives shelter to a wide variety of resident and migratory birds. Some of the bird species found in Caño Negro are very abundant and it is possible to spot hundreds of these birds, especially during the dry season. Commonly spotted bird species include anhingas, wood storks, jabirus, and neo-tropical cormorants.

Additionally, Caño Negro is home to monkeys, iguanas, sloths, caimans and turtles. Along the river it is possible to spot howler monkeys, spider monkeys, and white-faced monkeys, as well as three-toed sloths and several reptile species including basilisk lizards.

Regarding tourism services, the park offers an information area, park ranger station, trails, lodging, restrooms, and potable water.

Bosque Alegre Wildlife Refuge
To get to the refuge, depart from the community of Cariblanco; the secondary road winds for approximately 7 kilometers (about 4 miles).  An all wheel drive or 4WD vehicle is recommended for the journey.

This is a river group of volcanic origin, made up of the Bosque Alegro, Congo, and Hule Lagoons. During November, the waters of the Hule Lagoon turn red.

All of these lagoons are surrounded by tropical wet forest. A local community has assumed responsibility for caring for the wildlife refuge and assuring that its conservation and protection policies are followed.

Regarding services, Bosque Alegre offers trails, restrooms, potable water, lodging, and local naturalist guides.

Arenal Volcano National Park
Arenal Volcano National Park is located in northeastern Costa Rica, sandwiched between the Tilarán Mountain Range and the San Carlos Plains. The park is located 15 kilometers (about 9 miles) from the town of La Fortuna de San Carlos.

Arenal Volcano is one of the most visited destinations in the Northern Plains. The park offers several trails: Heliconias, Coladas (Lava Flows), Tucanes (Toucans), and Miradores (Lookout Points). The trails are ideal for bird and wildlife watching, hiking, and exploring black-rock lava flows. The park spans 12,124 hectares (almost 30,000 acres).

Arenal Volcano National Park offers a full range of services including an information booth, park ranger station, trails, phones, restrooms, and potable water.

Without a doubt, the park’s primary attraction is Arenal Volcano, which ascends to 1,663 meters (5,450 feet) above sea level. After many years of supposed extinction, the volcano roared to life in 1968, when it violently erupted. Arenal Volcano is still active and red-hot lava can be seen on most clear nights.

Juan Castro Blanco National Park
Located east of Ciudad Quesada, this park is surrounded by the districts of Aguas Zarcas, Venecia, Zapote, Laguna, Tapezco, Altamira, Sarchí Norte, Toro Amaraillo, and Río Cuarto, among others.

The area is marked by numerous thermal pools (Fila Chocosuela), active volcanic vents (Platanar Volcano), inactive volcanic vents (Cerro Viejo and Cerro Pelón), volcanic cones and rugged topography. Wildlife is very varied, and includes species such as quetzals, wild turkeys, chachalacas, black guans, monkeys, armadillos, agoutis, and tapirs, among others.

The park’s wetland resources give it a strategic importance in the region, since it is home to many hydrographical watersheds and numerous creeks and rivers. For example, the park is home to the headwaters of approximately 50 rivers including Tapesco, Peje, La Vieja, San Rafael, Aguas Zarcas, and Tres Amigos. Juan Castro Blanco is also the source of the Platanar and Toro River watersheds, which take advantage of the consistently wet surroundings to create hydroelectric power projects. The park is also home to several lagoons such as Pozo Verde and a few of Costa Rica’s largest waterfalls: Toro, Aguas Gatas, Gorrión, and Rio Claro.

Visitor services are offered in the San Jose de la Montaña sector and include an information office, trails, restrooms, and potable water.

La Selva Biological Station
La Selva Biological Station, of great biological value, is located at the junction of two large rivers in Puerto Viejo de Sarapiquí. The biological station spans 1,600 hectares (3,950 acres) of tropical wet forest and other terrain.

Fauna is very diverse. La Selva is home to large mammals including jaguars, pumas and tapirs. Thousands of arthrepod (invertebrate) species are currently registered as living at the biological station, which also protects and additional 400 bird species, both resident and migratory – almost half of the species currently residing in Costa Rica.

Because of its intense and varied biodiversity, the National Science Academy of the United States of America recognized La Selva Biological Station as one of the four most interesting and suitable places in the world for conducting research on tropical forests.

In 1954, Dr. Leslie Holdridge first established La Selva Biological Station, which receives some of the country’s heaviest amounts of precipitation. Dr. Holdridge dedicated the property to research and mixed plant experimentation with the hope of further improving the country’s natural resources management.

In 1968, La Selva was acquired by the Organization of Tropical Studies, which declared it a private biological reserve. Since then, it has become one of the most important sites in the world for research on tropical wet forests.

Children’s Eternal Forest – Poco Sol Biological Station
The Poco Sol Biological Station is located on the Atlantic slope of the Tilarán Mountain Range and sits at 720 meters (1,780 feet) above sea level. The station lies inside the boundaries of the Children’s Eternal Forest.

To get to Poco Sol, take the San Ramón-La Fortuna road approximately 50 kilometers (31 miles) until reaching the Monteverde Conservationist Association at La Tigra de San Carlos. From there, follow the road another 13 kilometers (8 miles) toward San Miguel de la Tigra.

Approximately 10 kilometers (6 miles) of trails surround Poco Sol, wending and winding through primary forest, secondary forest, and pastures in the process of regeneration. The biological station is home to a diversity of habitats including a 3.8-hectare (9.4-acre) lagoon, a waterfall, boiling thermal pools, and natural hot springs.

As at the San Gerardo Biological Station, the region’s forests are categorized as pre-montane wet forest, which is known for being evergreen. However, due to the biological station’s altitude and proximity to a transitional forest, the Poco Sol Biological Station demonstrates certain unique conditions regarding its biological diversity and scenic beauty.


Maleku Indigenous Reserve
Located just six kilometers (almost four miles) from San Rafael de Guatuso, the Maleku Indigenous Reserve offers tours within the Maleku community.
