Turtles nest at Ostional Wildlife Refuge all year long, but it is much more accelerated during the arribadas. During these fantastic events turtles can come in by the tens of thousands, literally covering the beaches!
Visitors are encouraged to seek the services of guides and tours, as they are the best way to see the nesting turtles and hatching areas. Turtles nest in the evening, so it is recommended to go to the park after 6pm. Admission to the refuge during arribadas is 10USD and includes a local guide.
