Timing is Everything for the Arribada

The main draw is the 'arribada,' a mass nesting of Olive Ridley sea turtles. This happens most reliably during the new moon phase, typically from September to November, but can occur year-round. Book a guided tour to witness this incredible natural phenomenon.

Respect the Turtles and Their Habitat

Ostional is a protected wildlife refuge. Always go with a certified local guide, use only red lights (no flashlights or camera flashes), and wear dark clothing to minimize disturbance. Your visit directly supports conservation efforts.

Reviews Summary

Visitors consistently describe Ostional Wildlife Refuge as an 'incredible' and 'magical' experience, particularly for witnessing the mass nesting of Olive Ridley sea turtles. The dedication of local guides and the raw beauty of the beach are highly praised. Some note that the refuge can feel understaffed and that facilities are basic, but the overwhelming sentiment is one of awe and appreciation for this natural wonder.

"Such an incredible experience! For $20 cash you can join the turtle tour (only possible with a guide, just go to the little restaurant at the beach). We went in the evening around new moon and saw hundreds of turtles coming up to lay their eggs — definitely one of the best things we did in Costa Rica."

Garcel von Mannikus

"A Massacre on the Sand…
I recently visited the stretch of beach near the Cemetery, and what I witnessed was not conservation, but a massacre. The path the tiny hatchlings must navigate to the ocean is neglected and hazardous:
• Environmental Debris: The sand is littered with hazards, including glass, plastic, and large, broken tree trunks that create impassable barriers for the emerging young.
• Uncontrolled Predation (Domestic Dogs): The most devastating threat comes from domestic dogs, which are permitted to roam freely. I saw multiple instances of dogs digging up nests, leaving behind hundreds of opened, empty eggshells. This is not natural predation; it is a direct consequence of lax security and community negligence.
• Scavenging Birds: Compounding the dog problem, scavenging birds are easily accessing the exposed nests, further contributing to the slaughter.
The result is heartbreaking. We are talking about hundreds of nests being destroyed before the hatchlings even have a chance to emerge. The sight of these dug-out, empty nests—a testament to a complete breakdown in security—is incredibly sad."

Monica Rodriguez

"stunning place to witness the beauty of sea turtles returning to the ocean. Sunset and early sunrise are the best times to visit for this incredible experience.

The workers here are kind and clearly passionate about protecting the turtles and the refuge. While it’s evident they’re understaffed and stretched thin, their dedication shines through. Supporting this amazing location, whether through donations or mindful visits, can go a long way in helping preserve its natural beauty and aiding the hardworking team."
