Costa Rica is a land of incredible biodiversity, and few natural events are as awe-inspiring as the arribadas – the mass nesting of sea turtles – at Ostional Wildlife Refuge. This unique phenomenon, where thousands of sea turtles come ashore to lay their eggs, is a truly unforgettable experience. If you’re planning a trip to Costa Rica, especially between July and December, witnessing this natural spectacle should be at the top of your list.
What is an Arribada?
Arribada is a Spanish word meaning “arrival.” It refers to the synchronized mass nesting of sea turtles, primarily Olive Ridleys, on the shores of Ostional. These events occur several times a year, typically during the rainy season, and can involve hundreds of thousands of turtles arriving over a period of several nights.
Why Ostional?
Ostional is one of the few places in the world where arribadas occur regularly. The unique combination of beach conditions, including the black sand and specific wave patterns, makes it an ideal nesting site for Olive Ridley turtles. The refuge was established in 1984 to protect this vital nesting ground and ensure the survival of these magnificent creatures.
When to Go:
The best time to witness an arribada is during the rainy season, which runs from July to December. The peak nesting months are typically September and October. However, smaller nestings can occur throughout the year. It’s important to note that the exact timing of the arribadas is unpredictable, as they are influenced by lunar cycles, tides, and weather patterns.
What to Expect:
Witnessing an arribada is a truly humbling experience. Imagine thousands of sea turtles emerging from the ocean under the cover of darkness, slowly making their way up the beach to dig their nests and lay their eggs. The sheer number of turtles, the sound of the waves, and the quiet determination of these ancient creatures create a truly magical atmosphere.
Important Guidelines for Visitors:
- Respect the turtles: Maintain a safe distance from the turtles and avoid disturbing them. Do not use flash photography or bright lights, as this can disorient them.
- Follow the instructions of your guide: It’s essential to visit Ostional with a certified guide who understands the regulations and can ensure the turtles are protected.
- Minimize your impact: Avoid littering and stay on designated paths.
- Be patient: The timing of the arribadas is unpredictable, so be prepared to wait.

While the arribada is the main attraction, Ostional and the surrounding area offer other activities, including:
- Wildlife watching: Keep an eye out for other wildlife, such as birds, monkeys, and iguanas.
- Beach walks: Enjoy the beautiful black sand beach and the surrounding natural scenery.
