The coast of Santa Cruz, Guanacaste, Costa Rica, stands as a privileged destination to witness one of the most extraordinary and significant events in the country: the arrival of leatherback turtles (Dermochelys coriacia), olive ridley turtles (Lepidochelys olivacea) and green turtles (Chelonia mydas). This phenomenon not only offers an impressive visual spectacle, but also underscores the importance of marine conservation. Two highlights for the observation of this amazing event are Playa Ostional and Las Baulas National Marine Park, in particular Playa Jesus. The preservation of these critical habitats is not only essential for turtle species, but also contributes to the marine ecological balance, making this experience a tangible reminder of the imperative need to protect our coastal biodiversity.
