My Costa Rica Journey – a continuing series dedicated to those who love nature and seek educational, enriching travel experiences – brings us today to Playa Grande and the Tamarindo Estuary, two of the most fascinating natural destinations in northwest Costa Rica. From leatherback turtles to exotic birds, mangroves to pristine beaches, this area of Guanacaste Province offers a true ecological adventure.
Exploring Playa Grande
Playa Grande is located just a few miles north of Tamarindo, along the northwest Pacific coastline. The beach stretches approximately 1 kilometer, featuring brown sand and deep blue waters. Palm trees line portions of the shore, providing pockets of shade, while the waves attract surfers from around the world, especially during high tide when offshore winds create ideal surfing conditions.
Since 1991, Playa Grande has been part of Marino Las Baulas National Park, established to protect the endangered leatherback turtles that nest here. This beach is one of the most important leatherback nesting sites globally, making it a haven for conservationists and wildlife enthusiasts alike.
Encountering the Leatherback Turtles
The leatherback turtles are the stars of Playa Grande. Nesting occurs from October through March, when females crawl ashore under the cover of night to lay their eggs. During my stay at Las Tortugas Hotel, which is grandfathered in due to government regulations requiring new constructions to be set 50 meters from high tide, my friend Renee and I witnessed one of these majestic creatures.
On a moonlit stroll, we saw a very large leatherback depositing her eggs in the sand. Unfortunately, Renee startled her with a small flashlight. A park ranger quickly intervened, reminding us of the strict rules: no flashlights, no cameras, and maintain a respectful distance. He emphasized that Playa Grande is one of the world’s most important leatherback nesting areas, and conservation is crucial for future generations.
For those who want a closer, safe encounter, hiring a naturalist guide is highly recommended. Guides lead tours starting around 9 p.m., patiently waiting for turtles to emerge. It may take hours, but the experience is unforgettable—watching these ancient reptiles return to the ocean is a humbling reminder of nature’s resilience.
Leatherback Turtle Facts
- Endangered species, with populations declining worldwide.
- Size: Can reach up to 6 feet long and weigh over 400 kg.
- Reproduction: Eggs hatch in approximately 60 days.
- Habitat: Ranges from the North Atlantic near the Arctic Circle to the South Pacific near New Zealand.
- Local population: Nesting females at Playa Grande dropped from 1,300 to around 140 per year over eleven years due to poaching and habitat destruction.
Conservation efforts are critical. National park regulations protect the turtles, and visitor compliance ensures their continued survival.
Tamarindo Estuary: A Wildlife Sanctuary
Just a few miles north of Las Tortugas Hotel lies the Tamarindo Estuary, the heart of the Tamarindo Wildlife Sanctuary. This estuary is protected both by the Costa Rican National Park System and the International Wetlands Protection Agency, making it an ecological gem for nature enthusiasts.
We booked a morning tour starting around 6 a.m.—the best time to see wildlife and enjoy cooler weather. Bird binoculars, mosquito repellent, and comfortable clothing are essential for this adventure.
We rented a canoe with a naturalist guide for $30 per person, though paddling it yourself is also an option. The estuary revealed a saltwater forest lined with tea mangroves, providing food and shelter for hundreds of species of birds and animals.
Wildlife Encounters in the Estuary
Our Tamarindo Estuary tour was a feast for the senses:
- Birds: A beautiful white osprey with black-tipped wings, a flock of hooded trogans, and a group of Amazon yellow parrots.
- Monkeys: We spotted a white-faced monkey carrying her baby along the riverbank.
- Reptiles: The American crocodile inhabits the estuary. Males can grow 6–7 feet long, though attacks on humans are extremely rare.
- Crabs: A spectacular sight was a parade of large red crabs marching in perfect formation back to the ocean—a rare natural event.
The Tamarindo Estuary is also home to the Guanacaste tree, a towering giant shaped like a mushroom, and a diverse lowland forest ecosystem. This estuary is a perfect example of Costa Rica’s dedication to wildlife conservation and ecotourism.
Where to Stay in Playa Grande
During our four-day adventure, we stayed at the Rip Jack Inn, a small inn located five minutes from the beach. It offers:
- Clean, tropical grounds
- Yoga classes at 8:30 a.m.
- Reasonable pricing and friendly staff
- Local management by a Canadian owner
Rip Jack Inn is ideal for travelers seeking a peaceful, eco-conscious stay with easy access to the beach, estuary, and surrounding natural attractions. For more information, visit: Rip Jack Inn.
