What to know first
Yes, you can see sea turtle nesting near Nosara at the Ostional National Wildlife Refuge.

Because timing and access change with natural conditions, plan flexibly, confirm current activity, and visit only with an authorized or accredited local guide who follows refuge rules.
Key takeaways
- Olive ridley turtles can nest at Ostional throughout the year, but the largest arribadas are generally associated with the rainy season, especially July through November.
- An arribada is a natural event, not a scheduled attraction, so no specific date can be guaranteed.
- Visitors should arrange the experience through an authorized or accredited local guide and follow current refuge instructions.
- Distance, low voices, no flash, permitted lighting, and staying with the guide help protect turtles, hatchlings, eggs, and nesting paths.
Can you see sea turtles near Nosara?
Yes. One of the most significant nature experiences near Nosara happens at Ostional, a coastal community north of town within the Ostional National Wildlife Refuge.
Ostional, Costa Rica, is known for the arribada, a mass-nesting event in which large numbers of olive ridley sea turtles come ashore to lay eggs. It can become one of the most meaningful parts of a villa stay, but the experience requires careful timing, local guidance, and respect for an active wildlife refuge.
The right way to visit is to stay flexible and put conservation rules ahead of the itinerary.
What is the Ostional arribada?
An arribada is a synchronized mass-nesting event. Instead of one turtle arriving at a time, many olive ridley turtles come ashore over a concentrated period to lay their eggs. The Spanish word arribada means arrival, and it describes the scale of what happens on the beach.
These events are connected to natural cycles, tides, moon phases, weather, and seasonal conditions. Nature does not follow a hotel itinerary, so visitors should avoid treating an arribada like a fixed attraction with a guaranteed showtime.
The strongest approach is to follow current local updates, work with an authorized guide, and treat access as a privilege rather than a spectacle.
When is the best time to see turtles in Ostional?
Turtle season in Costa Rica includes olive ridley nesting throughout the year, but official Costa Rica tourism guidance identifies July through November as the strongest period for seeing the large arribadas most travelers have in mind. Local conservation guidance notes that September and October often bring the largest events.
That makes Ostional especially relevant during Nosara’s green season, when the landscape is lush and wildlife activity can be particularly rich. Smaller or solitary nesting activity may happen outside the main rainy-season window.
No guide, hotel, or villa manager can responsibly guarantee an arribada on a specific date. If turtle nesting is a priority, leave room in the itinerary and coordinate close to the visit using current refuge and guide updates.
How far is Ostional from Nosara?
Ostional is north of Nosara and close enough for a guided half-day, sunrise, sunset, or evening outing. Visit Costa Rica places the refuge about 13 kilometers from Playa Guiones, although the practical travel time varies with the exact starting point, route, season, and road conditions.
For villa guests, coordinating transportation in advance is usually the most relaxed option, especially when access is early, late, or after dark. During the rainy season, road conditions deserve extra attention.
Do you need a guide to visit Ostional?
Yes. Turtle-nesting visits should be booked with authorized or accredited local guides following current refuge procedures. Official Costa Rica tourism guidance states that visitors can only enter the refuge for nesting observation with an accredited guide so the turtles are not disturbed.
Guides help manage visitor movement, explain the nesting process, confirm when access is possible, and adapt the visit to the conditions on the beach. Their role protects the turtles and usually makes the experience more understandable.
- Where visitors may stand and when they should move.
- How much distance to keep from nesting turtles.
- Which lights are permitted under current rules.
- How to avoid blocking a turtle’s path to or from the ocean.
- Why some areas may be restricted during active nesting.
How to visit Ostional responsibly
A turtle-nesting tour should be quiet, careful, and directed by the guide and refuge authorities. Current instructions always take priority over a general travel article.
Keep your distance
Turtles need clear space to move, nest, and return to the ocean. Follow the distance and positioning instructions given by your guide.
Avoid bright lights
Bright light can disturb nesting turtles and hatchlings. At night, use only the lighting explicitly permitted by your guide or refuge staff.
Do not use flash photography
Flash can interfere with wildlife and the nesting atmosphere. If photography is allowed, keep it discreet and follow the guide’s rules.
Stay with your guide
Do not wander across an active nesting beach. Restricted movement protects turtles, eggs, and routes between the sand and ocean.
Keep your voice low
Quiet behavior reduces disturbance and makes the experience more powerful for everyone present.
Never touch turtles or eggs
Observe without interfering. Do not touch, handle, block, or attempt to redirect wildlife.
Follow current local instructions
Access and viewing procedures can change with turtle activity and conservation needs. The guide and refuge authorities have the final word.
Why Ostional belongs on a Nosara itinerary

For families, the visit can be educational and unforgettable. Couples may experience it as a quiet, intimate outing, while groups often remember it as a shared story. For wellness travelers, it offers a broader sense of natural scale and place.
