Turtles in Costa Rica are among the most beloved animals from the country and many tourists from all over the world rush to Costa Rican beaches to catch the spectacular hatching show.
Costa Rica turtles hatching season lasts for the whole year because there are more species that come to these beaches to lay their eggs and the nesting season is different from one species to another.
It is quite hard to predict the exact date and time when the nesting season starts for each species as this is a natural phenomenon that is influenced by many natural factors like the phases of the moon, the ocean’s temperature, and so on.
This article will tell you which species of tortoise you can see laying eggs on Costa Rica beaches when the turtles hatching in Costa Rica and where to go to witness this unique spectacle.
The most amazing spectacle is the arribada which refers to the moment when thousands of turtles arrive on the beaches with the same goal, that of laying their eggs under the new moon.
If you are a wildlife lover and you are seeking unique natural shows, then this moment should be on your bucket list.
Now that you know which is the most spectacular moment of turtles hatching Costa Rica, let’s discover together which are the main species that come to Costa Rican beaches, when is the best time to see them, and where to go.

The 4 species of turtles in Costa Rica
The Pacific Coast, as well as the Caribbean coasts, are visited by the following Costa Rica sea turtles species:
- Olive ridley sea turtles
- Green sea turtles
- Leatherback sea turtles, the world’s largest sea turtle
- Hawksbill turtles
Arribadas is most spectacular at olive ridley when thousands of creatures come to the nesting beaches to lay their eggs and contribute to the perpetuation of their species.
The other three species of turtles that use the beaches for nesting and or hatching are endangered species, so the arribadas are not that spectacular as the number of individuals that come to lay their eggs is lower.
Like I said earlier, it is quite hard to predict the arribada moment and you should not plan your trip just for this event, but once you arrive at your hotel we strongly recommend you to check with the hotel reception if the arribada is taking place.
You cannot enter by yourself on a nesting and or hatching beach, you always have to be accompanied by a professional guide, so if the arribada happens when you are around, book a tour to see the show.
When is the best time to see sea turtles
As you cannot just rely on luck when seeing the impressive arribada show, knowing where to be in each month makes the difference between seeing or missing the moment when the turtles come.
Grab a pen and a piece of paper and write down this useful information to have with you when you travel to spot all types of sea turtles in Costa Rica.
Olive Ridley turtles
This beautiful turtle species offers the most impressive arribada show because of their impressive number of individuals that come to the nesting beaches from Costa Rica.
The nesting season is all year round, but the most impressive events happen in September and October and sometimes even in late November, depending on the year.
A few nights before the full moon turtles start to come to the beach and the event reaches its peak when there is a full moon.
Leatherback sea turtles
If you want to see these incredible creatures laying their eggs you need to head to the eastern coast of Costa Rica in the first part of the year, from February to June.
The peak season for leatherback turtles hatching in Costa Rica is in March and April, depending on the year.
If you plan your trip for the second part of the year, you might see these creatures on the western coast of Costa Rica anytime between October and February, but the arribada show is not that spectacular as the Olive Ridley arribada.
Unfortunately, hawksbill sea turtles are an endangered species and their numbers decreased fast in the last years so you really need to consider yourself lucky if you will see these sea turtles nesting on your trip to Costa Rica.
You will not see any arribada show as their numbers are really low and they generally nest alone especially in September and October.
Green Sea Turtles
These gentle creatures usually lay their eggs from July to early November with peak season August and September on the Pacific and Caribbean coast.
