What happens during turtle nesting season in Costa Rica?

Understanding turtle nesting behavior

• Sea turtles follow a precise natural cycle:
• Adult females return to the beach where they were born
• They dig nests and lay 80–120 eggs
• Eggs incubate for ~45–70 days
• Hatchlings emerge and move toward the ocean

This is why turtle nesting Costa Rica season is strictly regulated—only certified guides can accompany visitors to protect the species.

Key rules to follow

• Only visit with certified local guides
• No flash photography
• Wear dark clothing
• Maintain distance from turtles
• Stay quiet and avoid sudden movements

Costa Rica is one of the world leaders in conservation, and these rules are strictly enforced.

Our Experience with sea turtles in Costa Rica

Turtle watching alone is a powerful experience—but Costa Rica is much more:

• Volcanoes (Arenal)
• Cloud forests (Monteverde)
• Beaches (Pacific & Caribbean)
• Wildlife (sloths, monkeys, birds)

That’s why the smartest travelers don’t just “see turtles”—they build a complete journey around it.
