Ostional Wildlife Refuge, Costa Rica: Best Turtles, Solitude & Community Conservation (2026)
While crowds jostle for space at Tortuguero National Park, Ostional Wildlife Refuge, Costa Rica delivers one of the planet’s most profound wildlife spectacles in raw, unfiltered silence. Here, during an *arribada* (mass nesting event), over 100,000 olive ridley sea turtles can emerge in a single night, transforming three kilometers of black sand into a living, breathing tapestry of ancient instinct. This isn’t a staged show with bleachers; it’s a front-row seat to a primal ritual that has shaped this community for generations.

- Historic Architecture: The simple, functional ASADA community water tower, built in the 1980s, symbolizes the local cooperative management that saved the turtles and transformed the village’s destiny.
- Cultural Scene: The annual *Fiesta de la Tortuga* (Turtle Festival) in November celebrates the arribada with local food, music, and community-led educational tours about their unique conservation model.
- Local Specialties: Don’t miss *Gallo Pinto con Huevos y Plátano* at a local *soda*—the classic Costa Rican breakfast is the perfect fuel for a sunrise beach walk.
Pro Tip: To witness an arribada, plan your visit around the new moon or last quarter moon from July to December, with peak months being August through October. Always check with the local biological station or a registered guide the evening before, as arribadas are predicted by weather patterns, not guaranteed schedules.

Planning Your Trip: Practical Essentials
Getting There and Around
- By Air: Fly into Liberia International Airport (LIR) or Juan Santamaría International Airport (SJO) in San José. From Liberia, it’s a 2.5-3 hour drive; from San José, it’s 4.5-5 hours. Book flights at Skyscanner for best deals.
- By Train: No direct train service is available to this remote Pacific coast region.
- By Car: A 4×4 vehicle is highly recommended, especially in the rainy season. The final 10km from the town of Santa Cruz to Ostional is a rugged, unpaved road. Compare car rentals at RentalCars.com.
- Local Transport: Public buses run from San José and Liberia to Santa Cruz, where you can take a local taxi (often a 4×4) for the final leg to Ostional. Schedules are infrequent, so renting a car offers crucial flexibility.
Best Time to Visit
The best time to visit is dictated by turtle activity. The dry season (December to April) offers easier road access and sunny weather, but the major arribadas occur in the rainy season (July to December). This is a trade-off between accessibility and the chance to witness the refuge’s main event.
| Season | Weather | Highlights |
|---|---|---|
| Rainy / Arribada Season (Jul–Dec) | Warm, humid, with afternoon showers (75-90°F). Roads can be challenging. | Peak chance to witness mass nesting arribadas. Lush green scenery. Fewer general tourists. |
| Dry Season (Dec–Apr) | Hot, sunny, and dry (80-95°F). Perfect beach weather. | Reliable road access. Great for seeing solitary nesters and hatchlings. Ideal for general beach relaxation. |
| Shoulder (May–Jun) | Transitional, with increasing humidity and sporadic rain. | Very few visitors. Lower accommodation rates. You may catch the tail end of sporadic arribadas or early solitary nesters. |

3-Day Itinerary: Ostional Wildlife Refuge, Costa Rica’s Highlights & Hidden Gems
Day 1: Arrival & Immersion in Turtle Culture
- Morning (7-9 AM): Arrive early from Liberia or San José. After checking into your cabina, head straight to the Ostional Biological Station. Check the arribada forecast and arrange your mandatory guide for the evening. The staff are incredibly knowledgeable.
- Afternoon (12-3 PM): Enjoy a casual lunch at Soda La Plaza in the village center for a massive *Casado* (rice, beans, plantains, salad, and choice of protein). Then, take a solo walk along the southern end of Ostional Beach (daytime access is free) to scout the landscape.
- Evening (6-8 PM): If an arribada is predicted, meet your guide at the designated time (often around 8 PM). If not, take a guided night walk ($25) to look for solitary nesting turtles, a more intimate and equally magical experience.
Day 2: Arribada Dawn & Coastal Exploration
- Morning (5-7 AM): Dawn is the best time to see the scale of a major arribada. Return to the beach with your guide (often included if you did a night tour) to see turtles finishing nests and the first hatchlings potentially making a dash for the sea. The light is sublime for photography.
- Afternoon (12-3 PM): Recover with a late breakfast at your lodge. Then, drive 15 minutes north to Playa San Juanillo. The twin coves here, with their calm, clear water and rock formations, are perfect for a swim. Have a fresh ceviche lunch at Rancho San Juanillo, right on the sand.
- Evening (6-8 PM): Enjoy a relaxed dinner at your accommodation. Spend time chatting with local guides or owners about the community’s conservation journey, a story more compelling than any documentary.
Day 3: Community Connection & Departure
- Morning (7-9 AM): If it’s a market day (ask locally), visit the small community stalls. Consider a surf lesson ($40) on the consistent beach breaks of Ostional—the water is warm and the crowd is non-existent.
- Afternoon (12-3 PM): For your final meal, grab a *batido* (fruit smoothie) and a tasty empanada from a roadside stand. Make one last visit to the beach to reflect. Ensure you’ve left a donation at the Biological Station—it directly funds patrols and research.
- Evening (6-8 PM): Begin your journey out, or if staying, consider a night kayaking tour in nearby mangroves (bookable through lodges) to see bioluminescence and a different ecosystem.
Cultural Insights & Etiquette
- Language: Spanish is key. Learn: “*Buenas*” (hello), “*Gracias*” (thank you), “*¿Hay arribada?*” (Is there an arribada?). Locals appreciate the effort immensely.
- Customs: This is a tight-knit community that depends on turtle conservation. Respect is paramount. Always follow your guide’s instructions to the letter on the beach—your actions can impact nesting success.
- Tipping: Not mandatory but highly appreciated for guides. A 10-15% tip on a tour fee is a great way to support the local economy directly.
- Dress Code: On the beach at night: dark clothing (black or navy), no white. No flashlights or camera flashes unless explicitly approved by your guide. During the day, standard beachwear is fine.
- Business Hours: Everything runs on “tico time”—relaxed and flexible. Small sodas may close early. The Biological Station keeps fairly standard hours, but guides are available based on turtle activity, not a 9-to-5 schedule.
Where to Eat: Ostional Wildlife Refuge, Costa Rica’s Best Bites
Dining in Ostional is about simplicity and freshness. You won’t find gourmet restaurants, but you will find hearty, home-cooked Costa Rican fare, often with seafood caught just offshore. Most meals are served at your lodge or in the village’s few sodas.
Must-Try Local Specialties
- Fresh Ceviche: Made with local corvina or dorado, lime, cilantro, and onions. Best enjoyed at a beachfront *rancho* like the one in San Juanillo.
- Arroz con Mariscos: A flavorful rice dish packed with whatever seafood was fresh that day. Your lodge kitchen often makes the best version.
- Patacones: Twice-fried green plantains, smashed and served as a side with almost every meal, often topped with black beans or guacamole.

Where to Stay

Best Neighborhoods for Accommodation
- The Village Center: You’re steps from the Biological Station, sodas, and the beach access point. Perfect for total immersion, though accommodations are more basic. Ideal for budget travelers and serious turtle enthusiasts.

FAQs: Your Ostional Wildlife Refuge, Costa Rica Questions Answered
1. Is Ostional Wildlife Refuge, Costa Rica safe at night?

2. What currency is used and are credit cards accepted?
The currency is the Costa Rican Colón (CRC). US dollars are sometimes accepted at lodges. Carry ample cash (colones) as credit cards are rarely accepted in the village sodas, for guide fees, or donations. The nearest reliable ATM is in Santa Cruz or Nicoya.
3. How do I get from the airport to Ostional?
From Liberia Airport (LIR), rent a 4×4 for the 2.5-3 hour drive via Nicoya and Santa Cruz. Private shuttle services can be booked but are expensive ($150+). Public bus involves a transfer in Santa Cruz and can take 4+ hours. Book airport transfers at GetYourGuide for convenience, but confirm the vehicle can handle the final unpaved road.

5. What’s the appropriate dress code?
For turtle watching: dark, long pants and sleeves to protect from bugs, closed-toe shoes you don’t mind getting sandy. For daytime: standard beachwear, a hat, and strong sunscreen. Always have a rain jacket handy in the green season.
