Manuel Antonio National Park: History, Facts and Visitor Guide
Manuel Antonio National Park was established in 1972 and covers 1,685 acres of coastal rainforest and protected marine area on Costa Rica's Central Pacific coast. It is one of the smallest national parks in Costa Rica and one of the most biodiverse — this guide covers the park's history, what makes it ecologically significant, and everything visitors need to know before arriving.

How Manuel Antonio National Park Was Created
The park's origin story is rooted in citizen action. In the late 1960s, local residents and international conservationists recognised that rapid development — logging, agricultural clearing and unregulated construction — was destroying the coastal rainforest and beaches that made the area extraordinary. A sustained advocacy campaign directed at the Costa Rican government eventually succeeded: the park was officially established in 1972, protecting 1,685 acres of land and 55,000 acres of surrounding ocean. The Quitirrí indigenous community had lived in the area for centuries before the park's creation — their relationship with the land informed early conservation knowledge. The park was later expanded in 1984 to include the Punta Catedral headland and additional forest buffer zones.
Biodiversity: Why Manuel Antonio Is Ecologically Significant
Manuel Antonio National Park contains one of the highest concentrations of wildlife per square kilometre of any protected area in Costa Rica — remarkable given its relatively small size. The park protects habitat for over 100 mammal species, 180 bird species, and dozens of reptile and amphibian species. Four monkey species — white-faced capuchin, squirrel monkey, howler and spider — all occur within the park. The endangered Central American squirrel monkey (mono tití) is found in Manuel Antonio and very few other locations globally. The protected marine area offshore supports coral reef ecosystems, sea turtles and a seasonal humpback whale migration. The park's small size relative to its biodiversity makes it one of the most studied ecosystems in tropical conservation research.
The Trails and Beaches of Manuel Antonio National Park
The park has four main trails and four beaches accessible to visitors. Sendero Principal (Main Trail) connects the park entrance to Playa Manuel Antonio — easy, 2km, the most visited trail. Sendero Perezoso (Sloth Trail) is a shorter loop through old-growth forest and the most reliable trail for sloth sightings. Sendero Punta Catedral loops around the rocky headland with Pacific ocean views from the peninsula. Sendero Congo reaches the more remote sections of the park with lower visitor numbers. The beaches — Playa Manuel Antonio, Playa Espadilla Sur, Playa Gemelas and Playa Biesanz (just outside the park) — each have distinct character from calm swimming coves to open surf breaks. All park beaches require the entrance fee.
Conservation Challenges and Ongoing Efforts
Manuel Antonio faces conservation pressures common to small, highly visited parks. The daily visitor cap — strictly enforced and requiring advance online booking — was introduced specifically to prevent the trampling, wildlife harassment and habitat degradation that uncontrolled visitor numbers cause. The Central American squirrel monkey remains endangered and is the subject of active monitoring and habitat protection programmes. Illegal feeding of wildlife by visitors is one of the park's most persistent management challenges — fed monkeys become aggressive, dependent and shorter-lived. Reef protection in the marine area requires enforcement against boat anchoring and chemical sunscreen use. The park's small size means every visitor decision — staying on the trail, not feeding animals, using reef-safe sunscreen — has a measurable impact on the ecosystem.
Practical Information for Visiting Manuel Antonio National Park
The park is open Tuesday through Sunday, 7am to 4pm — it is closed on Mondays. Entrance tickets must be purchased online in advance at sinac.go.cr — walk-up entry is not guaranteed and the park sells out completely during the Dry Season high season (December through April). The daily visitor cap is strictly enforced. Bring water, reef-safe sunscreen, insect repellent and closed-toe shoes for trails. A certified naturalist guide significantly improves wildlife sightings and is recommended for first-time visitors. Guides are available at the park entrance but pre-booking is advisable. No food vendors operate inside the park — bring snacks if you plan to spend more than two hours. The main park entrance is 5 minutes from Makanda by the Sea by car.
Visiting Manuel Antonio National Park from Makanda by the Sea
Makanda by the Sea is positioned 5 minutes from the Manuel Antonio National Park entrance — one of the closest boutique hotel locations to the park in the area. This proximity allows for 6:30am departures that put you inside the park at opening, before trails get busy and while wildlife is most active. Makanda reception can connect you with certified naturalist guides, help arrange early morning transport, and advise on current trail conditions and wildlife activity based on recent guest reports. Book your park tickets at sinac.go.cr before arrival — particularly important between December and April when the park sells out weeks in advance. Browse our tours and activities page for guided park visit options, or contact reception directly to plan your visit.
