Tortuguero National Park, National park in Limón Province, Costa Rica

Tortuguero National Park is a protected area on the Caribbean coast of Costa Rica that includes rainforest, wetlands, and a network of navigable canals. The park covers both terrestrial and marine zones, with waterways winding through dense jungle and providing access to remote habitats.

Tortuguero was declared a national park on 24 September 1970, and its boundaries were modified three times, in 1980, 1995 and 1998, to take in more territory. Its area grew from 64,701.45 to 76,937 hectares, of which 50,284 are marine and 26,653 terrestrial. Within the land area, 99% is reserved for absolute protection of resources and 1% serves as a visitor site.

The village of Tortuguero, beside the park, keeps the boat-and-bicycle transport of the Caribbean coast, and the Dr. Archie Carr Wildlife Refuge runs a turtle tagging programme there. At the Cuatro Esquinas ranger station, architect and sculptor Ibo Bonilla designed the visitor centre, whose helical stairways and the sculpture "Tortuguero Pura Vida" have become a stop on the route.

The park can only be reached by boat, as no roads lead into the area. Boat trips through the canals usually depart from the port town of Moín or from smaller docks along the waterways.

The area hosts eleven different habitats that together support more than two thousand plant species and four hundred tree varieties. The beaches serve as the most important nesting site for green sea turtles in the entire Western Hemisphere.
