Interesting Facts About Costa Rica: Nature, Culture, History & Hidden Gems

Here’s a number that stops most people cold: Costa Rica holds roughly 5% of everything alive on Earth, packed into a country that covers just 0.03% of the planet’s land surface. That’s the kind of density that makes scientists just as obsessed with this country as travelers are.

We’ve lived and worked here long enough to know the facts everyone repeats (pura vida, no army, lots of sloths) and the ones almost nobody mentions (the unusual address system, the shark-filled island, and the government program that literally regrew the forests). Whether this is prep for your first trip to Costa Rica or your fifth, this list covers both.

Here’s what’s ahead:

• Nature & Wildlife: the real biodiversity numbers, the national animal nobody guesses correctly, and the island most tourists never visit

• Culture & Daily Life: what pura vida actually means, what Ticos eat, and the Blue Zone hiding in plain sight

• History & Politics: the country that disbanded its own army and never looked back

• Hidden Gems & Quirks: the misconceptions worth clearing up, and the details that surprise even repeat visitors

Let’s get into it.

Nature & Wildlife

This is the category most people come for, and it doesn’t disappoint. Costa Rica’s ecosystems punch so far above their weight that scientists still can’t fully explain it.

1. Costa Rica Packs 5% of the World’s Species Into 0.03% of Its Land

That biodiversity stat up top isn’t an exaggeration. Costa Rica sits at the meeting point of North and South America, a land bridge formed roughly 3 million years ago, and species from both continents ended up mixing here. The result is somewhere around 500,000 known species crammed into a country roughly the size of West Virginia.

You’ll feel this the moment you step into any patch of rainforest. It’s rarely quiet.

2. The National Animal Isn’t a Monkey

Ask most visitors to guess Costa Rica’s national animal, and you’ll hear “sloth” or “monkey” almost every time. It’s actually the white-tailed deer, declared the official symbol of Costa Rican fauna back in 1995.

The national bird is just as understated: the yigüirro, or clay-colored thrush, chosen not for its looks but for its song, which locals associate with the start of the rainy season.

3. Ostional’s Turtle Arribada Can Bring in Hundreds of Thousands of Sea Turtles

Every year, thousands of olive ridley sea turtles crawl ashore at Ostional Wildlife Refuge on the Nicoya Peninsula in a synchronized event called an arribada, Spanish for “arrival.” Between Ostional and its sister beach, Nancite, Costa Rica’s Pacific coast supports an estimated 600,000 nesting olive ridleys.

Time your trip right (a few nights around the last quarter moon, August through November), and you can watch it happen from the sand.

4. Monteverde’s Cloud Forest Exists Because Two Oceans Argue Over It

The Monteverde Cloud Forest Reserve sits on a mountain ridge where warm, moist air rolling in from the Caribbean collides with cooler air from the Pacific side. That collision condenses into a near-constant mist, which is exactly what a cloud forest needs to exist.

Walk through it, and you’ll understand why. Everything drips. Everything glows green. It doesn’t feel like anywhere else you’ve been.

5. Cocos Island Is a Real Lost World, and Almost Nobody Goes There

About 550 kilometers off Costa Rica’s Pacific coast sits Cocos Island, the largest uninhabited island on Earth and a UNESCO World Heritage Site since 1997. It’s covered in the only tropical rainforest found on any Pacific island, and its surrounding waters host massive schools of scalloped hammerhead sharks.

Getting there takes a 36-hour boat ride, which is exactly why it’s stayed this wild. It’s also rumored to be the inspiration behind Jurassic Park’s island setting.

6. The Government Actually Regrew the Forests

Back in the 1980s, Costa Rica’s forest cover had dropped to around 40% of the country as cattle ranching and logging expanded. Instead of accepting that, the government created the Payment for Environmental Services (PES) program, which pays landowners directly to conserve or replant forests.

It worked. According to the World Bank, forest cover has climbed back to over 60% of the country today, one of the only nations to reverse deforestation at that scale.

Culture & Daily Life

Costa Rica’s culture is where the “pura vida” reputation actually comes from, and it goes deeper than a phrase on a T-shirt.

7. Pura Vida Means More Than “Pure Life”

You’ll hear “pura vida” as a greeting, a goodbye, a thank you, and an answer to “how are you,” often all in the same conversation. It’s less a phrase and more a worldview: stay easygoing, appreciate what’s in front of you, don’t sweat what you can’t control.

Say it back when someone says it to you. It’s genuinely the right response almost every time.

8. Costa Ricans Call Themselves Ticos, Not Costa Ricans

Locally, nobody says “Costa Rican” in casual conversation. Costa Ricans call themselves Ticos (Ticas for women), a nickname that comes from an old linguistic habit of adding ‘-tico’ as a diminutive suffix to words. Use it, and you’ll get a smile of recognition almost every time.

9. Gallo Pinto Is Breakfast, Lunch, and a National Identity

Gallo pinto, rice and black beans cooked together with onion, pepper, and cilantro, shows up on breakfast plates across the country, often alongside eggs, plantain, and a slice of local cheese. It’s simple food, but it’s the dish Costa Ricans get genuinely nostalgic about when they’re abroad.

• Rice and black beans: the base of gallo pinto, plus a staple of lunch and dinner “casado” plates

• Plantain: fried, boiled, or mashed, and present at nearly every meal

• Coffee: grown in volcanic highland soil since the 19th century, and still a point of national pride

10. There’s a Blue Zone Where People Regularly Live Past 100

The Nicoya Peninsula is one of only five Blue Zones in the world, regions where an unusually high number of people live active, healthy lives well into their 90s and beyond. We’ve written a full breakdown of what makes Costa Rica’s Blue Zone so unusual, from the diet to the water quality, if you want to go deeper.

11. Spanish Here Has Its Own Flavor

Costa Rican Spanish carries loanwords and expressions from Indigenous languages like Bribri and Chorotega, plus its own regional slang that can trip up Spanish speakers from other countries. “Mae” (like “dude”) gets used constantly across every age group.

History & Politics

This is the category most travel articles skip, and it’s honestly one of the more interesting parts of the country’s story.

12. Costa Rica Abolished Its Army in 1948 and Never Brought It Back

On December 1, 1948, President José Figueres Ferrer officially abolished Costa Rica’s military by symbolically breaking down a wall of an army barracks. The move followed a brief civil war, and the money once spent on defense was redirected into education and healthcare instead.

Nearly 80 years later, Costa Rica remains one of the few countries in the world with no standing army at all.

13. Independence Came Without a Single Battle

Costa Rica declared independence from Spain on September 15, 1821, the same date celebrated across Central America. Unlike many independence movements in the region, Costa Rica’s transition happened peacefully, largely because the country was remote and lightly governed by Spain to begin with.

14. The Country Declared Itself Permanently Neutral

In 1983, Costa Rica formally declared permanent, active neutrality, a stance later reinforced by former president and Nobel Peace Prize laureate Óscar Arias Sánchez, who helped broker peace across a region that was otherwise consumed by civil wars in the 1980s.

15. It’s Consistently Ranked One of the Happiest Countries on Earth

Costa Rica has repeatedly topped the Happy Planet Index, a ranking that measures wellbeing against ecological footprint rather than raw GDP. No standing army, strong social programs, and near-universal healthcare all factor into why.

Hidden Gems & Quirks

These are the details that catch even repeat visitors off guard.

16. Costa Rica Is Not an Island

This one comes up more than you’d expect. Costa Rica is a mainland country in Central America, bordered by Nicaragua to the north and Panama to the south, with a coastline on both the Pacific Ocean and the Caribbean Sea. No ferry is required to get here.

17. Nobody Uses Street Addresses

Most of Costa Rica doesn’t rely on street names or building numbers. Instead, addresses are given as distance and direction from a landmark, often a church, a soccer field, or even a business that closed years ago. A typical address might read “200 meters north of the old Pizza Hut.”

According to the Tico Times, each “block” is assumed to be 100 meters regardless of its actual length. It sounds chaotic. It works.

18. The Country Runs Almost Entirely on Water, Wind, and Volcanoes

Costa Rica generated 98.6% of its electricity from renewable sources in 2025, drawing from hydropower, geothermal plants built into volcanic zones like Guanacaste, wind, biomass, and solar. Hydropower alone typically supplies the majority of that mix.

Geothermal energy here comes directly from the same volcanic activity that shapes the landscape you’ll be hiking through.

19. Two Coastlines, One Country, Completely Different Vibes

The Pacific coast runs about 630 miles and tends toward big surf breaks, dry-season sunshine, and towns like Tamarindo. The Caribbean coast, only about 132 miles long, feels entirely different: slower, more reggae-influenced, with a distinct Afro-Caribbean culture around towns like Puerto Viejo.

Same country, roughly a four-hour drive apart, and it can genuinely feel like two different destinations.

20. It’s Roughly the Size of West Virginia

Costa Rica covers about 51,100 square kilometers, which puts it right around the size of West Virginia, or a touch larger than Denmark. Small on the map, and somehow still home to over 200 volcanoes and more than 500,000 species.

21. Medical Tourism Is a Bigger Deal Than Most Visitors Realize

Costa Rica has become one of the top medical tourism destinations in the Americas, drawing visitors for dental work, cosmetic procedures, and elective surgery at a fraction of U.S. prices, often paired with a recovery stay near the beach. It’s a big enough industry that several private hospitals here hold U.S. accreditation.

Quick-Fire Facts to Round It Out

A few more things worth knowing before you go.

• The colón is the national currency, named after Christopher Columbus (Cristóbal Colón in Spanish)

• San José, the capital, sits in the Central Valley at a cooler, higher elevation than the coast

• Guanacaste province has its own tropical dry forest ecosystem, unlike the wetter rainforest found elsewhere in the country

• Sugar cane has been grown here since colonial times and remains a major export crop

• Manuel Antonio National Park, despite being one of the smallest national parks in the country, is one of the most visited for its beaches and easy wildlife spotting

• The sun rises and sets around 5:30 a.m. and 5:30 p.m. year-round, since Costa Rica sits close to the equator and doesn’t observe daylight saving time

• The country has two seasons, not four: a dry season (roughly December to April) and a green, rainier season the rest of the year

• Sloths move so slowly that algae actually grows on their fur, giving them a greenish camouflage in the canopy
