Costa Rica Fun Facts: 28 Amazing Facts to Know

Costa Rica is small, but it packs in huge natural variety. The country has coasts on both the Pacific Ocean and Caribbean Sea. Its forests shelter an extraordinary range of life. Official tourism sources estimate that Costa Rica holds about 5% of the world’s known biodiversity, while about 26% of its land is protected.

There is more to Costa Rica than beaches and rainforests. The country abolished its army in 1948. It also became a global example of renewable electricity. In 2025, renewable sources produced 98.6% of its electricity.

I find Costa Rica most interesting when nature meets daily life. Here are 28 Costa Rica fun facts that show that connection.

1. A Small Country With Huge Biodiversity

1. Costa Rica holds remarkable biodiversity.
Costa Rica covers only about 51,100 square kilometers. Yet its ecosystems support roughly 5% of the world’s known biodiversity, according to the country’s tourism authority. That includes forests, wetlands, beaches, mountains, rivers, and marine habitats. Its location between North and South America helps many species move through the region.

2. More than one quarter of its land is protected.
About 26% of Costa Rica’s land mass is protected. This protection covers national parks, wildlife areas, forests, and other conservation spaces. The country manages these places through SINAC, its National System of Conservation Areas. SINAC currently divides the country into 11 conservation areas.

3. Costa Rica has two very different coasts.
The Pacific Ocean lies west of Costa Rica. The Caribbean Sea lies east. Mountains run through much of the country and help create different rainfall patterns. The Pacific and Caribbean sides therefore have different local climates, even though both are tropical.

4. Its size makes its species density striking.
Costa Rica is much smaller than many countries with similar biological richness. Its compact territory contains many habitats close together. A traveler can move from lowland forest to mountain ecosystems within a relatively short distance. That sharp change in elevation helps explain its unusual ecological variety.

2. The Country That Gave Up Its Army

5. Costa Rica abolished its army in 1948.
On December 1, 1948, José Figueres Ferrer formally abolished the Costa Rican army. The event took place at the Bellavista military barracks. The building later became the National Museum. The decision became one of the defining events in modern Costa Rican history.

6. The abolition later entered the Constitution.
Costa Rica’s 1949 Constitution prohibited the army as a permanent institution. It provided for police forces to maintain public order. This constitutional rule remains a distinctive feature of Costa Rica’s political system. The country is therefore unusual among nations because it does not maintain a standing military.

7. The old barracks became a museum.
The Bellavista barracks was not simply abandoned after the army ended. It became the National Museum of Costa Rica. The transformation created a powerful symbol. A former military building became a place for history, culture, education, and public learning.

8. December 1 is linked to the decision.
Costa Rica officially commemorates December 1 as the Day of the Abolition of the Army. The national observance was established by executive decree in 1986. The date keeps the 1948 decision visible in public memory, especially through education and cultural events.

3. Cocos Island Is Far Out in the Pacific

9. Cocos Island sits hundreds of kilometers offshore.
Cocos Island lies about 550 kilometers from Costa Rica’s Pacific coast. Its extreme isolation makes it very different from mainland parks. UNESCO describes it as an oceanic island with tropical rainforest and highly important marine ecosystems. The surrounding waters are famous for large pelagic animals.

10. Cocos Island is a World Heritage Site.
UNESCO added Cocos Island National Park to the World Heritage List in 1997. The site was later expanded in 2002. Its value comes from both land and sea ecosystems. The protected property covers about 199,700 hectares, most of which is marine area.

11. The island has many endemic species.
Cocos Island has species found nowhere else. UNESCO records about 70 endemic vascular plant species. It also lists endemic birds, reptiles, and freshwater fish. Long isolation allowed unusual evolutionary processes to continue on the island.

12. Its waters attract large marine animals.
Cocos Island is famous for sharks, rays, tuna, dolphins, and other large marine species. UNESCO records about 300 fish species around the protected area. Hammerhead sharks are especially well known there. The island’s location also helps marine species move through the region.

4. Pura Vida Is More Than a Tourist Slogan

13. “Pura Vida” literally means “pure life.”
The phrase “Pura Vida” is strongly linked with Costa Rican identity. People use it as a greeting and as an expression of happiness. Its everyday meaning can be closer to “full of life.” It has become one of the best-known cultural phrases associated with Costa Rica.

14. The phrase became popular through popular culture.
Research from the University of Costa Rica traces the expression’s modern rise in Costa Rica to the 1950s and later decades. A Mexican film called Pura Vida helped spread the phrase. By the 1970s, it had become especially popular among young Costa Ricans.

15. Pura Vida can describe a feeling.
The phrase does not always function as a simple greeting. It can express approval, happiness, gratitude, or a relaxed attitude. That flexibility helps explain why two short words became closely tied to Costa Rican culture.

16. Language can become part of national identity.
Costa Rica shows how a casual expression can grow into a cultural marker. “Pura Vida” now appears across tourism, conversation, advertising, and everyday social life. It is not an official national motto, but it is widely recognized as an unofficial symbol of the country.

5. Costa Rica Runs on More Than Sunshine

17. Renewable energy supplied 98.6% of electricity in 2025.
Costa Rica produced 98.6% of its electricity from renewable sources during 2025. The national electricity institute, ICE, reported the figure after verification. The sources included hydropower, geothermal energy, wind, biomass, and solar power. This is one of Costa Rica’s strongest environmental achievements.

18. Hydropower is one major energy source.
Costa Rica’s renewable electricity system uses several technologies. Hydropower plays a major role because the country has many rivers and mountainous areas. Geothermal, wind, biomass, and solar power also contribute. Using several sources reduces dependence on one type of renewable energy.

19. Geothermal power uses volcanic heat.
Costa Rica sits in a volcanically active region. That creates useful underground heat. Geothermal plants can use this natural heat to generate electricity. This makes volcanic activity more than a geological curiosity. It can also become part of the country’s energy system.

20. The renewable figure is time-sensitive.
Electricity production changes each year because rainfall, wind, demand, and plant output change. The 98.6% figure applies specifically to 2025. It should not be presented as a permanent yearly percentage. For future articles, this number should be checked against the latest ICE report.

6. Nicoya Has a Remarkable Longevity Story

21. Nicoya is known as a Blue Zone.
The Nicoya Peninsula is one of the places commonly identified as a Blue Zone. Research has found unusually high longevity among older residents in parts of the region. The recognized area includes five cantons: Carrillo, Santa Cruz, Nicoya, Hojancha, and part of Nandayure.

22. Scientists have studied mortality patterns there.
Research found lower mortality among older people in the Nicoya region than in the wider Costa Rican population. The findings helped support the idea of unusual longevity in the area. Scientists have examined factors such as lifestyle, diet, social connections, and living conditions.

23. A Blue Zone does not mean everyone lives longer.
The Blue Zone label describes a population pattern. It does not guarantee exceptional health for every resident. Researchers study groups and statistical trends. This distinction matters because popular articles sometimes turn population findings into simple promises about diet or lifestyle.

24. Nicoya adds another layer to Costa Rica’s story.
Costa Rica is often discussed through wildlife and conservation. Nicoya shows another side of the country. Human longevity has also attracted scientific attention. That makes the region interesting for both environmental researchers and population scientists.

7. Costa Rica’s Nature Is Also Under the Water

25. Costa Rica protects important marine ecosystems.
Costa Rica’s conservation system is not limited to forests. Protected areas can include land, wetlands, and portions of the sea. This matters because marine ecosystems support fish, sharks, turtles, coral communities, and migratory species. Conservation therefore extends beyond what visitors see on land.

26. Cocos Island has an unusual marine role.
Ocean currents meet around Cocos Island and influence marine life there. UNESCO describes the island as a dispersal center for larvae from marine species. Its isolated position creates important links between ocean currents and biological processes.

27. Costa Rica has more than 900 bird species.
The Costa Rican Tourism Institute reports more than 900 bird species in the country. That number is striking for such a small territory. Its forests, mountains, wetlands, and two coastlines create many habitats for resident and migratory birds.

28. Conservation is part of tourism management.
Costa Rica actively manages tourism inside protected wildlife areas. SINAC and the Tourism Institute promote responsible visits and wildlife protection. Visitor activities can be controlled through management plans. This approach connects tourism with conservation rather than treating nature as an unlimited resource.
