The Arribada: Witness Costa Rica's Marvelous Sea Turtle Migration

Embark on a journey to Costa Rica's pristine shores, where the sands come alive with thousands of Olive Ridley sea turtles in a breath-taking natural spectacle known as the "arribada."

A Natural Phenomenon Like No Other

Imagine standing on a moonlit beach, the sound of gentle waves caressing the shore, when suddenly, the horizon fills with the silhouettes of countless sea turtles emerging from the ocean. This is the arribada, a mass nesting event unique to Olive Ridley sea turtles. Costa Rica is one of the few places on Earth where you can witness this awe-inspiring occurrence.

‍

The Olive Ridley Sea Turtle

Named for the olive hue of their heart-shaped shells, Olive Ridley sea turtles are among the smallest of their kind, yet they embark on one of the most extraordinary journeys in the animal kingdom. After traversing vast ocean distances, they return to the very beaches where they were born to lay their eggs, continuing the cycle of life.

‍

Ostional National Wildlife Refuge: The Epicentre of the Arribada

Located on the Nicoya Peninsula, the Ostional National Wildlife Refuge is the premier destination to experience the arribada. Established in 1984, the refuge protects critical nesting grounds and supports sustainable local practices that benefit both the community and the turtles.

‍

When to Visit

The arribada occurs year-round but is most frequent during the rainy season, from July to December, often aligning with the last quarter of the moon. Peak events can see up to 300,000 turtles nesting over a few days.

‍

An Unforgettable Experience

Visitors can join guided night tours led by certified local guides, ensuring minimal disturbance to the turtles while providing insightful information about their behaviour and conservation status. Walking among these gentle creatures as they laboriously dig nests and lay eggs is a humbling experience that connects you deeply with nature.

Beyond Ostional: Other Turtle Nesting Sites

While Ostional is the most renowned spot for the Olive Ridley arribada, Costa Rica offers several other exceptional locations to witness sea turtle nesting:

Tortuguero National Park

Known as the "Land of Turtles," Tortuguero National Park on the Caribbean coast is one of the most important nesting sites for the Green Sea Turtle. From July to October, thousands of these magnificent creatures come ashore. The park is also a nesting ground for Leatherback, Hawksbill, and Loggerhead turtles.

Gandoca Manzanillo Wildlife Refuge

Located near the Panamanian border, the Gandoca Manzanillo Wildlife Refuge is a critical nesting site for the Leatherback Sea Turtle, the largest of all sea turtles. Nesting season runs from March to July, offering a unique opportunity to see these giants up close.

Corcovado National Park

On the remote Osa Peninsula, Corcovado National Park features secluded beaches where Olive Ridley and Hawksbill turtles nest. The park is a biodiversity hotspot, making it an excellent destination for wildlife enthusiasts.

Manuel Antonio National Park

While less frequented by nesting turtles, Manuel Antonio National Park occasionally hosts sea turtles on its picturesque beaches. Combined with its lush rainforest and abundant wildlife, it offers a well-rounded natural experience.
