Ostional National Wildlife Refuge is an essential nesting site for olive ridley sea turtles, offering visitors the unique opportunity to witness mass turtle nesting events.
Located on the Pacific coast of Costa Rica, Ostional National Wildlife Refuge is best known for its role in protecting the olive ridley sea turtles that nest on its beaches. Established in 1984, the refuge encompasses 85 hectares of riverine and coastline habitat that supports a range of flora and fauna.

The refuge also includes mangroves and tropical dry forests, which are vital for the ecological diversity of the area. In addition to turtle watching, visitors can enjoy pristine beaches and explore rich biodiversity. The local community collaborates closely with conservation efforts, offering tours that educate about marine life and conservation.
