June to November – Sea Turtle Season

Sea turtles are commonly seen year around in the waters of our Golfo Dulce (“sweet gulf”). However, the main nesting season on the peninsula is from June until December. We have 4 species that nest on our beaches: olive ridleys, green turtles, hawksbill turtles, and leatherbacks. Olive ridley turtles are the most common species found nesting on beaches around the Osa. A small population of the more endangered hawksbill sea turtles live in the Golfo Dulce.
