Do: Visit Manuel Antonio National Park Manuel Antonio National Park is one of the country's most popular parks, and offers excellent wildlife spotting; species that make their homes here include howler monkeys, white-faced capuchin monkeys, toucans, and iguanas. The park also has four stunning white-sand beaches. There is a daily per person entrance fee. Stay: Arenas Del Mar Beach and Nature Resort Arenas Del Mar is within walking distance of the park, and has direct access to the beautiful Playitas Beach and Playa Espadilla. Wildlife spotting is superb right on the property -- Arenas del Mar went to great lengths not to disrupt the surrounding ecosystem during the hotel's construction. Arenas del Mar is proof that staying at an eco-resort doesn't mean roughing it: The resort embodies rustic luxury.
