FAQ

Questions about wildlife in Costa Rica

All year. December to April is dry and easier to travel; May to November is green, with more frogs, nesting turtles and fewer people. Pick the month by the animal: quetzals nest February to May, turtles July to November, and humpbacks visit July to October and December to March.

It depends on the animal. Manuel Antonio for sloths and monkeys on a short visit, Monteverde for cloud-forest birds, Tortuguero for turtles, and the Osa for the longest list. Each animal tile above shows its best place.

Very rarely. Even guides in Corcovado go years between sightings. Pumas there are a small chance; camera trap tours show what passed at night.

Seven days covers two regions well. Ten to fourteen lets you add the cloud forest or the Osa without spending most days on the road.

In Corcovado, yes: entry requires a guide certified by the ICT. Elsewhere it is optional, but a guide's eye and scope find animals most visitors walk past.
