Manuel Antonio National Park, on Costa Rica’s central Pacific coast, encompasses rugged rainforest, white-sand beaches, and coral reefs. It’s renowned for its vast diversity of tropical plants and wildlife, from three-toed sloths and endangered white-faced capuchin monkeys to hundreds of bird species. The park’s roughly 680 hectares are crossed with hiking trails, which meander from the coast up into the mountains. We highly recommend taking an early morning guided tour of the park with a professional naturalist guide to avoid the crowds and increase your odds of seeing more wildlife. Naturalist guides have an eye and an ear for locating wildlife that most people miss.
