The honest answer is that no one really knows. Costa Rica has no official record for people who have visited every national park in the country. There is no public registry, no national stamp book, no completion certificate and no organization that tracks the achievement in the way some travelers track visits to all 50 U.S. states, every U.S. national park or all 193 United Nations member countries.
That makes the full Costa Rica national park challenge one of the country’s least documented adventure goals. It is also far harder than many visitors realize.
Costa Rica protects more than a quarter of its territory through a national system of protected areas that includes national parks, wildlife refuges, biological reserves, forest reserves, wetlands, protected zones and national monuments. Within that system are 30 formal national parks managed under Costa Rica’s conservation structure.
Visiting one or two is easy. Millions of travelers have been to Manuel Antonio, Poás Volcano, Irazú Volcano, Tortuguero, Cahuita, Marino Ballena or Arenal. Completing the full list is different. It requires months of planning, significant money, physical preparation and access to places that are remote, lightly developed or difficult to reach.
Some parks are familiar to almost every traveler who has spent time in Costa Rica. Manuel Antonio has beaches, wildlife and one of the country’s most accessible park experiences. Poás and Irazú can be reached on day trips from the Central Valley. Arenal, Cahuita, Marino Ballena and Rincón de la Vieja are regular stops on tourist itineraries.
Others are rarely visited by comparison. Barbilla, Juan Castro Blanco, La Cangreja, Diriá, Miravalles Jorge Manuel Dengo and Piedras Blancas see far less traffic and often require more local knowledge. Some have limited visitor information, fewer services and less predictable access than the better-known parks.
Then there are the parks that create the real barrier.
Cocos Island National Park is the hardest. It sits about 550 kilometers off Costa Rica’s Pacific coast and can only be reached by boat, usually on a multi-day liveaboard diving expedition from Puntarenas. There are no hotels, no ferry service and no casual day trip. The crossing alone takes roughly 36 hours each way, and a full expedition can cost several thousand dollars per person.
For most people who love Costa Rica’s national parks, Cocos Island is the one that makes completion unrealistic.
La Amistad International Park is another major obstacle. The park is part of a vast protected mountain region shared with Panama and recognized by UNESCO for its global environmental importance. On the Costa Rican side, it is remote, rugged and difficult to explore deeply without serious preparation. Visitor access covers only a small portion of the protected area, and indigenous territories near or within the broader region add another layer of access considerations.
Corcovado National Park is more accessible than Cocos or La Amistad, but still demanding. Visitors need advance reservations, certified guides for most routes and careful planning around boat access, tide conditions and ranger station availability. During high season, overnight spaces can sell out well in advance.
Tortuguero presents a different challenge. It is one of Costa Rica’s most famous parks, but there is no road access to the main village. Visitors arrive by boat or small plane, and travel must be planned around river transport, weather and lodge schedules.
Volcano parks can also complicate a completion attempt. Poás, Irazú, Rincón de la Vieja and Turrialba are all shaped by changing volcanic conditions, and access can be limited or adjusted depending on current activity, gas levels, trail safety and official restrictions.
Below is the working list of Costa Rica’s 30 national parks, with their main access area or general location. Several parks cross provincial or conservation-area boundaries, so the locations below are meant as practical visitor references rather than strict legal boundaries.

| 29 | Tortuguero National Park | Northern Caribbean coast, Limón |
| 30 | Turrialba Volcano National Park | Turrialba Volcano area, Cartago |
Cabo Blanco deserves special mention because it is often grouped with national parks in travel writing. It is one of Costa Rica’s most important protected areas and the country’s oldest nationally protected forest area, but its formal category is Cabo Blanco Absolute Natural Reserve, not national park.
For someone trying to visit all 30 national parks, the challenge is not only distance. It is also classification, access, reservations, weather, transport, guides and cost. A traveler could visit the easier mainland parks over several weeks, but Cocos Island alone requires a separate expedition. Corcovado, La Amistad and Tortuguero require dedicated planning. Several lesser-known parks may require local calls, private transport or direct coordination with park offices.
A well-resourced traveler could attempt all 30 in a year with careful planning. Doing it casually during normal Costa Rica vacations would be extremely difficult. That is why the number of people who have visited every Costa Rican national park is almost certainly very small. Any precise number would be guesswork. No public authority appears to track it, and no recognized completion community exists at any meaningful scale.
What is clear is that visiting all 30 is one of Costa Rica’s most underrated adventure challenges. It is not a simple checklist. It is a test of logistics, patience and commitment to seeing the country far beyond the parks that appear on standard tourist maps.
