When Is the Best Time

Playa Grande in Costa Rica on the west coast is one of the very view places where leatherback's nesting sites are fully protected by law. The residents and researchers are taking care of for more than 30 years already the reason Playa Grande and Playa Ventanas became one of the biggest nesting sites in the world and protected by law in the Marino Las Baulas National Park. Thanks to their efforts more than a million leatherback hatchlings leave the nests in January.

Turtle Watching Season

Hatchlings are digging out of their nest

The best time to spot leatherbacks or hawksbill sea turtles arriving in the night is from October until March with its peak in January. Some leatherbacks come with a delay to lay their eggs so there is the possibility to spot baby turtles until May.

No light, flashlight is allowed to avoid disturbing a red light only. Taking pictures is almost impossible. If a female turtle gets disturbed she won't lay eggs and crawls back to the sea.

The best chances for a guided tour are within two hours before and after high tide. Why? During high tide, the way to the nesting place is shorter due to the higher sea level. Turtles are not made for crawling on land; they are excellent swimmers. Tide Times Playa Grande

Playa Grande and Playa Ventanas are accessible from 6 am to 6 pm on your own from October to the end of February the main nesting season. Please, don't walk on the upper parts of the beaches you may step on one of the nests. During the evening and night, all lights are switched off nearby the beaches. They really care about the future of the leatherbacks.

Top Tip 

Each night only a limited number of visitors are allowed to observe turtles coming ashore. It's essential to book a guided tour at the Las Baulas ranger station in advance to take part. We asked our accommodation to arrange the booking for us. Tour Fee: $25 - Passport has to be shown before!

We spent a couple of days close to Playa Grande. Both beaches stretch for 6 km almost 4 miles along the sea. It is a fantastic place to be during the day and night. Book your accommodation in advance that you can walk easily to the Minae office at night.

National Park Marino Las Baulas

Costa Rica

The Marino Las Baulas National Park was developed in 1990 to protect the endangered leatherback turtle eggs from poachers. Hundreds of female leatherbacks come ashore each year to lay their eggs and the number is continuously growing. It is one of the most important nesting sites in Costa Rica.

The meeting point

To observe turtles, you need to book a guided tour. The ranger let you know when to come to the turtle protection centre at night. To minimize your impact, you are guided in a small group by a ranger or researcher. We were fortunate and observed an approximately 450 kg heavy and 2 m long leatherback turtle laying eggs. On this night arrived a second turtle as well.

A volunteers digs out all laid turtle eggs

The next morning, we saw a National Park volunteer digging for eggs in the hatchery to protect them from poachers.

The eggs are buried again behind the fence. The nests are guarded by volunteers each night for the entire season.

I enjoy this beautiful scenery - currents occur not safe for swimming.

The white sand beaches are incredibly beautiful. The dry tropical forests are home to are a huge variety of wildlife and more than 170 bird species. Several white-throated magpie-jays observed us while having lunch.
