Bring your inner nature lover to Tortuguero National Park, a unique protected ecosystem where the freshwater runoff of the rainforest meets seawater along the Caribbean coast. The islands, wetlands, canals, lagoons and beaches are best explored by boat and present exceptional examples of biodiversity. Watch for spider monkeys hanging down over the river, caimans, many species of birds, river otters and the namesake turtles as you cruise through this National Park.
