Costa Rica is one of the world’s top wildlife destinations, but knowing when to look is just as important as knowing where. Different animals follow distinct daily and seasonal patterns, meaning the best time to spot sloths, monkeys, birds, sea turtles, whales, or frogs can vary by hour, month, and region.

From early-morning birding in cloud forests to night walks for nocturnal species, and from turtle nesting seasons on the Caribbean and Pacific coasts to whale-watching windows, timing makes all the difference.
