Playa Ostional is one of few beaches in the world where you can witness an Olive Ridley Sea Turtle ‘arribada’ (meaning ‘arrival’). The Refuge protects 15km of beach where, under cover of the new moon, turtles ride the high tide waves to shore and crawl up the beach to dig massive nests where they will each deposit up to 100 eggs! This amazing phenomenon is one of the most spectacular natural events you can witness. The eggs take between 45 to 65 days to hatch, at which point the baby turtles start to break from their shells and make their way to the ocean.

While Mother Nature keeps her own schedule, turtles generally nest just before the new moon when the skies are the darkest and hatch the largest arrivals (called an ‘arribada’ in Spanish), which happen between July and December. We’ll meet up with our certified guide and walk the beach to observe these massive turtles making their way from the ocean to the beach and back. Afterward, we’ll enjoy a traditional breakfast before heading back to your vacation rental.
