Tortuguero National Park is the best place in Costa Rica to encounter wildlife. It consists of a large system of waterways irrigating the majority of the Northern Caribbean area of the country. Because of its remote location and difficult access this pristine rainforest remains virtually untouched and it is home to many animals like sloths, monkeys, crocodiles, toucans, trogons, water birds, colorful frogs and butterflies. This National Park is also the prime nesting site for the green and leatherback sea turtles from July to October, during which months an optional turtle nesting night tour will be available.
