This morning, head to Tortuguero National Park for a boat tour of the canals. This park, established in 1970, is now home to 13 of Costa Rica’s 16 endangered mammals, including manatees, ocelots and jaguars. This is also the nesting ground of the green turtle, which comes ashore between July and October to lay its eggs on the beach. The hawksbill turtle, loggerhead turtle and giant leatherback turtles also nest within the park, but at different times of the year. This afternoon, maybe wander around some of the park’s walking trails or just kick back and relax at your lodge. Tonight, you might want to head out on a turtle-watching tour – part of the cost of this optional activity will support a program to patrol the beach for poachers, keeping the turtles and their eggs safe.
