Imagine walking along a Costa Rican beach beneath the night sky while learning about one of nature's most remarkable events: sea turtle nesting.

Ostional is internationally known for its arribadas — events when large numbers of turtles come ashore to nest over a short period. If your visit coincides with nesting activity, you may have the opportunity to observe turtles on the beach while learning about their life cycle and the conservation efforts that protect them — witness one of Costa Rica's most extraordinary wildlife events.
Learn about the olive ridley sea turtles that nest along this stretch of Costa Rica's Pacific coast. Depending on the conditions and activity that evening, you may have the chance to observe turtles coming ashore or nesting.
Discover what makes an arribada so remarkable, why large numbers of turtles may nest together, and how this natural event differs from an ordinary nesting night.
Experience the coastal environment in the evening with a guide who can explain the local wildlife and the importance of protecting the nesting beach.
Ostional is known for its community-based sea turtle conservation efforts. Learn how local conservation practices and wildlife management help protect nesting habitat and support the long-term survival of sea turtles.

Ostional, on Costa Rica's Pacific coast, is renowned for the mass nesting events of olive ridley sea turtles known as arribadas. During these events, many turtles arrive on the beach over a relatively short period to lay their eggs. The timing and size of an arribada vary — visiting during a period of nesting activity can create an extraordinary wildlife experience, but even during the broader nesting season, a large arribada may not be underway.
An evening in Ostional offers a chance to learn about Costa Rica's sea turtles and the conservation efforts protecting their nesting grounds. If the timing is right, you may witness a remarkable natural event that few travelers ever experience. Plan your visit responsibly, respect the wildlife, and let nature set the pace.
