Caño Negro Wildlife Refuge

Northern Lowlands region of Costa Rica

Caño Negro Wildlife Refuge is located in the northern part of Costa Rica, near the border with Nicaragua. It encompasses a vast area of wetlands, including a network of rivers, lagoons, and marshes. The refuge is situated in the Alajuela Province, within the larger Northern Lowlands region of Costa Rica. Here are some key aspects of Caño Negro:

Geography and Hydrology:

The wetlands of Caño Negro are primarily formed by the Frio River and its tributaries. The region experiences a tropical climate, characterized by distinct wet and dry seasons.

During the rainy season, the water levels rise, flooding the plains and creating an intricate system of waterways. This flooding is essential for maintaining the health of the wetlands and supporting the diverse array of life that depends on it.


Caño Negro is celebrated for its exceptional biodiversity, which includes a wide variety of flora and fauna. The wetlands provide a habitat for numerous bird species, amphibians, reptiles, mammals, and fish.

The area is especially renowned as a birdwatcher’s paradise, with over 350 species of birds recorded. Notable bird species include herons, egrets, ibises, anhingas, and the rare and endangered Jabiru stork.

The refuge is also home to various mammals, such as howler monkeys, white-faced capuchin monkeys, jaguars, ocelots, and river otters.

Migratory Stopover:

Caño Negro serves as a crucial migratory stopover for birds traveling between North and South America. The wetlands provide a resting place and a reliable source of food for these birds during their long journeys.

The timing of the migration season varies, but generally, it peaks during the North American winter, attracting a diverse range of migratory species.

Conservation Status:

The Caño Negro Wildlife Refuge was established in 1984 to protect the unique ecosystems and biodiversity of the region. The refuge covers an area of about 25,100 acres (10,170 hectares).

Conservation efforts in the area focus on preserving the delicate balance of the wetlands, minimizing the impact of human activities, and promoting sustainable tourism practices.

Tourism and Access:

Caño Negro has become a popular destination for eco-tourism and birdwatching. Visitors can explore the wetlands through guided boat tours, providing an opportunity to observe wildlife in its natural habitat.

The proximity of Caño Negro to other popular tourist destinations in Costa Rica, such as La Fortuna and Arenal, makes it accessible to travelers seeking diverse natural experiences.

Challenges and Conservation Efforts:

Like many ecologically sensitive areas, Caño Negro faces threats from human activities, including agriculture and development. Conservation organizations and local authorities work to balance the needs of the local communities with the imperative to protect the unique biodiversity of the region.

In essence, Caño Negro stands out as a prime example of the delicate interplay between geography, hydrology, and biodiversity. Its designation as a wildlife refuge underscores its importance in the ongoing efforts to conserve and appreciate Costa Rica’s natural heritage.
