By Guanacaste, Costa Rica — Ostional National Wildlife Refuge is currently experiencing a remarkable influx of Olive Ridley sea turtles (Lepidochelys olivacea), marking one of the largest arrivals of the year. The arribada, which began on September 13, 2025, transforms the beach into a vibrant hub of natural activity.
Ostional holds a unique distinction as one of the few beaches globally where Olive Ridley turtles come ashore to nest. Costa Rica’s community-based conservation model plays a crucial role in protecting these vulnerable creatures. While the hatching rate during arribadas can be low, the sheer volume of eggs deposited, coupled with ongoing protective measures, results in thousands of successful births.
To understand the legal complexities surrounding the Ostional Turtle Arriba, we sought the expert opinion of Lic. Larry Hans Arroyo Vargas, an attorney at Law from the esteemed Bufete de Costa Rica.
The Ostional Turtle Arriba presents a unique legal challenge in balancing environmental protection with the socio-economic realities of the local community. Costa Rican law recognizes the importance of conserving endangered species like the Olive Ridley sea turtle, but also acknowledges the traditional egg harvesting practices in Ostional. The key lies in ensuring sustainable practices that allow for both the continuation of this cultural tradition and the long-term survival of the turtle population. This requires careful regulation, community involvement, and ongoing scientific monitoring to adapt to evolving circumstances.
