Tortuguero which means ‘Region of Turtles’ in Spanish is nesting ground for sea turtles every year from March to mid-October. This nesting period known as the arribadas occurs when the moon is fading. Therefore, if you wish to see these turtles nest, it will be after 6:00 pm with a guide, as no one is allowed to explore the beach unaccompanied after this time. A great way to see the turtles nest is from a boat, canoe, or kayak off shore, so as not to disturb the turtles during their nesting or mating period.
