Yes, there are crocodiles in Costa Rica’s ocean, but only in certain places. American crocodiles live in the country’s rivers, estuaries and mangroves, tolerate salt water and sometimes swim into the surf, mostly near river mouths on the Pacific coast. They’re seen at Tamarindo, Playa Grande, Jacó, Playa Hermosa, Boca Barranca and Esterillos, among other beaches. Attacks are rare, and most serious ones have happened in or right beside rivers and estuaries. Swim and surf away from river mouths, stay out of murky water after heavy rain and obey the warning signs, and the risk is very low.
This guide is for beachgoers, surfers and families who want to know where crocodiles turn up, how real the danger is and what to do if you see one. It also covers where to see crocodiles safely.

The basics
Are There Crocodiles in the Ocean in Costa Rica?
The American crocodile is the species you’ll see. Unlike many crocodiles, it tolerates salt water, so it moves between rivers, mangrove estuaries and the sea. Most of the time it stays in rivers and estuaries, where food is easy to find. It shows up in the ocean mainly where a river meets the beach, and it sometimes swims along the coast between river mouths.
That overlap is why surfers notice them. River mouths build the sandbars and points that make good waves, and the same rivers carry fish that crocodiles feed on. Heavy rain pushes more water, and sometimes crocodiles, downstream into the surf zone.
Costa Rica also has the spectacled caiman, a much smaller relative that lives in freshwater rivers, lagoons and wetlands rather than the sea.
Where
Costa Rica Beaches Where Crocodiles Are Seen
| Beach or area | Where to be careful |
|---|---|
| Tamarindo and Playa Grande, Guanacaste | The Tamarindo estuary between the two beaches. Don’t swim across or paddle near the mouth; take the boat across. |
| Jacó, Central Pacific | The Quebrada Bonita estuary at the north end and the quieter south end near Playa Hermosa |
| Playa Hermosa (south of Jacó) | River mouths along the beach; crocodiles have been filmed in the surf lineup |
| Boca Barranca, near Puntarenas | The river mouth beside the long left-hand wave |
| Esterillos, Central Pacific | Stream and river mouths; a sighting once paused an international surf event |
| Nosara, Guanacaste | River mouths, mostly after heavy rain |
| Tambor, Nicoya Peninsula | The shoreline near river outlets |
| Caribbean coast | Rivers, canals and lagoons, including around Tortuguero |
Warning signs (“Peligro: cocodrilos”) mark many of these spots, and the government has been adding more along rivers and beaches. The list isn’t complete: any beach next to a river or mangrove can have a crocodile. See our guides to Tamarindo, Boca Barranca and the Central Pacific surf coast and Nosara.
The risk
How Dangerous Are Crocodiles in Costa Rica?
The risk is real but small. Given how many people swim and surf in Costa Rica, serious attacks are rare. Most have happened in rivers or right at estuary mouths, not on open beaches.
- 2016, Tamarindo: an American surfer near the estuary mouth was attacked and lost part of his leg.
- 2023, Guanacaste: a man was killed after jumping into the Cañas River near Santa Cruz.
Sightings at beaches have become more common in recent years, and phone videos make them spread quickly. Rip currents remain a far bigger danger to swimmers; read our guide to beach safety and rip currents and our tips for staying safe in Costa Rica.
Stay safe
How to Stay Safe from Crocodiles in Costa Rica
Costa Rica’s environment ministry and tourism board give the same core advice:
- Stay away from river mouths, estuaries and stagnant water. Swim and surf on open stretches of beach, well away from where any river or creek meets the sea.
- Obey the signs and don’t swim where swimming isn’t allowed.
- Keep well back from the water’s edge in rivers and mangroves; officials suggest at least 50 meters.
- Never feed crocodiles, and don’t leave fish scraps or food waste near the water. Feeding them is illegal and makes them bolder.
- Watch children and pets closely near rivers and estuaries.
- On boat tours, keep hands and feet inside the boat.
- Avoid flooded rivers and murky water in the rainy season.
Surfers
Tips for Surfing Where There Are Crocodiles
- Paddle out from open sand, not from beside a river mouth, even if the channel looks like an easy route out.
- Don’t cross estuary channels by paddling or wading, especially between Tamarindo and Playa Grande.
- Be extra careful at dawn and dusk, when crocodiles feed and light is low.
- After heavy rain, choose another break. Brown water hides animals and means rivers are pushing into the surf.
- Surf with others and listen to local surfers, lifeguards and surf schools, who usually know about recent sightings.
- Beginners: the shallow inside where lessons happen can be close to river mouths, so ask your instructor where it’s safe.

See them safely
Where to See Crocodiles Safely in Costa Rica
- Tárcoles River bridge (Route 34): the “crocodile bridge” about an hour to an hour and a quarter from the San José airport and about 30 minutes north of Jacó. Large crocodiles bask on the banks below. Park at the shops just north of the bridge, tip the parking attendant (about ₡500) and have someone stay with the car. Watch children; the railings have gaps. See our Carara National Park guide.
- Tárcoles River boat tours: leave from the town of Tárcoles and last about 1.5 hours, with crocodiles and waterbirds up close.
- Tamarindo estuary boat tours: guided trips through the mangroves between Tamarindo and Playa Grande.
- Tortuguero canals: crocodiles and caimans are common on canal tours. Read how to get to Tortuguero.
