Costa Rica is one of the most important sea Turtle nesting destinations in the world. Every year, thousands of sea turtles return to its protected beaches to lay eggs, creating one of nature’s most powerful wildlife spectacles. From the Caribbean coast of Tortuguero to the Pacific beaches of Ostional and Playa Grande, Costa Rica offers multiple opportunities to witness nesting turtles in their natural habitat. This premium 4,000-word guide explains when to go, where to visit, what species you’ll see, how tours work, and how to book ethical turtle nesting experiences.
Sea Turtle Species That Nest in Costa Rica
Costa Rica hosts five of the world’s seven sea turtle species: Green Sea Turtle, Olive Ridley, Leatherback, Hawksbill, and Loggerhead (rare). Each species nests in different regions and months. Green sea turtles dominate Tortuguero’s Caribbean beaches, Olive Ridleys create mass arribadas in Ostional, and Leatherbacks nest in Playa Grande and Gandoca-Manzanillo.
