Species expert program
Lyferr certifies guides one species at a time. A Crocodile Expert has the strongest proven record on Lyferr for finding and photographing crocodiles safely, which makes them your best odds for a good sighting and a good shot.
At launch, we award Founding Expert badges to guides with several years of premium tours focused on this species. Each one is confirmed or removed once the guide has logged 20 trips on Lyferr. After that, the badge is earned with logged trips and score.
No guide can promise a sighting. The badge shows the strongest track record for this species, not a guarantee.

When to go
All year. Sunny mornings in the dry season, December to April, are best, when crocs haul out on the sandbanks to warm up and the rivers are low.
Why a guide matters
From the bridge you'll see crocs. A good boat guide gets you more by:

Ask Lyferr a questionBest light is the first two hours after sunrise, when crocs bask with their mouths open.
Ethical wildlife watching
Yes, on most beaches. Attacks are rare, and almost all happen at or near river mouths, often at dawn, dusk or after heavy rain. Ask locals and lifeguards, and look for warning signs.
Never swim in rivers or estuaries, and keep kids and pets away from the water's edge.
No, and it is dangerous. Fed crocodiles learn to approach people and boats. Choose tours whose guides never feed them.
Never pay to hold or pose with a baby crocodile. Real rescue centres don't offer it.

Find a no-touch guideMyths and edge cases
There are no alligators in Costa Rica. The American crocodile does swim in the sea and moves between river mouths along the coast, which is why it sometimes turns up on beaches.
The Tárcoles bridge is free and safe. Crocs gather on the sandbanks below. Watch from the walkway, never from the riverbank.
Males bellow and slap the water in the dry season.

FAQ
No. Costa Rica has the American crocodile and the spectacled caiman. Many locals call crocodiles "lagartos", which adds to the confusion.
No. Lyferr is a marketplace. Licensed local guides and tour operators list their tours here, and we rank them by sighting success, reviews and client experience (and photography expertise for photo tours). You book and pay the deposit through Lyferr, and the operator you choose runs the tour.
Sometimes, near river mouths. Crocs swim along the coast between rivers. Most beaches are fine; avoid swimming near estuaries, especially at dawn and dusk.
Generally yes, away from the river mouths. Ask local surf schools which breaks have had croc sightings this season.
They bask in the morning sun and hunt at dusk and at night.
Group river tours cost about $35 to $65 per person and last about two hours. Every tour on Lyferr shows its price before you book.
Yes, almost every day. The bridge is on Route 34, about 1.5 hours from San José. Watch from the walkway and mind the traffic.
Large males on the Tárcoles River reach about 4 to 5 m. Most crocs you see are 2 to 3 m.
No. Feeding wildlife is illegal in Costa Rica, and fed crocs learn to approach people.
Cocodrilo, though many Ticos say lagarto. The caiman is the caimán or babilla.
