Manuel Antonio National Park, is a small National Park in the Central Pacific Conservation Area located on the Pacific coast of Costa Rica, just south of the city of Quepos, Puntarenas, and 132 km from the national capital of San José. Established in 1972 with a land area enumerating 1 983 ha (the smallest of any Costa Rican national park), it is the destination of as many as 150,000 visitors annually and well known for its beautiful beaches and hiking trails. In 2011, Manuel Antonio National Park was listed by Forbes Magazine among the world's 12 most beautiful national parks.

Although Manuel Antonio National Park is Costa Rica's smallest national park, the diversity of wildlife in its 6.83 km2 is unequaled with 109 species of mammals and 184 species of birds. Both brown-throated three-toed sloth and Hoffmann's two-toed sloth are a major feature, as are three of Costa Rica's four monkey species — the mantled howler monkey, Central American squirrel monkey, and white-headed capuchin monkey. black spiny-tailed iguana, green iguana, common basilisk, white-nosed coati and many snake and bat species are also common in the park. Included in the 184 bird species are toucans, woodpeckers, potoos, motmots, tanagers, turkey vulture, parakeets and hawks. Dolphins can be observed there, as well as the occasional migrating whale. Scuba diving, snorkeling, sea kayaking, mountain biking, and hiking provide opportunities to experience the tropical wildlife that enriches Manuel Antonio.

The Pacific Ocean in front of Manuel Antonio Park is also world-renowned for its fishing.

From November to April it is not uncommon for a typical angler to release multiple billfish in the over-100-pound range
