Playas del Coco Costa Rica – Complete Travel Guide

The word arribada means “arrival,” and in Costa Rica it describes the mass nesting of olive ridley turtles on selected Pacific beaches. Instead of arriving one by one, hundreds or even thousands of turtles come to shore during the same period, usually over several nights. This makes arribada one of the most impressive wildlife spectacles in the country.

The best-known place to see arribada in Costa Rica is Ostional Wildlife Refuge in Guanacaste. This beach is world famous for its turtle nesting activity and attracts travelers, photographers, and nature lovers from around the globe. Another important nesting area is Naranjo Beach in Santa Rosa National Park, although Ostional is the most accessible and popular location for guided visits.

The best months to experience turtle nesting in Costa Rica are usually September, October, and November. Arribada events often happen around the full moon and may last several days. Activity is typically strongest at night, which is why most turtle tours are organized in the evening or after dark. Timing can vary depending on ocean and moon conditions, so flexibility is important when planning your trip.

Ostional Beach is one of the few places in the world where massive arribadas occur on a regular basis. Watching olive ridley turtles emerge from the ocean, cross the dark sand, and begin nesting is an unforgettable moment. This is not just a tourist attraction — it is also a vital conservation area where access is controlled in order to protect the turtles and their habitat.

If you want to see turtles in Ostional, the best choice is to visit with an authorized guide. Guided visits help protect the nesting area, support local conservation efforts, and ensure that visitors follow the correct rules. Responsible tourism is essential: no flash photography, no loud noise, no touching the turtles, and no disturbing nests or hatchlings.

For travelers interested in wildlife tours in Guanacaste, arribada is one of the most memorable natural events in Costa Rica. It is ideal for families, photographers, and nature lovers who want to experience something truly special beyond beaches and volcanoes. If your trip takes place during turtle nesting season, adding Ostional arribada to your itinerary can become one of the highlights of your vacation.
