Costa Rica is mostly known for sloths, world-class surf, and that "Pura Vida" lifestyle that everyone tries to bottle up and take home. But there’s a weirder side to the country that doesn't always make the tourism brochures. If you spend enough time talking to pilots at Tobías Bolaños International Airport or farmers in the rural highlands of Arenal, you’ll realize that Costa Rica UFO sightings aren't just fringe conspiracy theories; they are a deeply embedded part of the local culture.
It’s weird.
For a country so small, the density of unexplained aerial phenomena is staggering. We aren't just talking about blurry lights in the distance that could be a DJI drone or a weather balloon. We are talking about some of the most scientifically vetted photographic evidence in the history of ufology.
The Lago de Cote Incident: A Global Gold Standard
You can’t talk about Costa Rica UFO sightings without talking about September 4, 1971. Honestly, it’s the "big one."
A specialized Aero-Commander F680 aircraft was flying at about 10,000 feet over Lake Cote. This wasn't a joyride. It was a mapping mission for the National Geographic Institute of Costa Rica. They were using a professional-grade mapping camera—a massive piece of equipment that snapped high-resolution photos at regular intervals.
In one specific frame, numbered 1200, something impossible appeared.
On the left side of the frame, hovering just above the surface of the lake, was a metallic, saucer-shaped disc. It wasn't there in the frame before. It was gone in the frame after. Because the camera was fixed and the altitude was known, researchers like Richard Haines and Jacques Vallée were able to perform actual math on the image. They estimated the craft was roughly 160 feet in diameter.
The "Cote Lake UFO" is still considered by many experts, including those from the French government’s GEIPAN (the official body for investigating UAPs), as one of the most authentic UFO photographs ever taken. No trickery. No double exposure. Just a giant metal disc caught in the act.

Why the Orosi Valley is a Hotbed
The Orosi Valley is beautiful. It’s lush, green, and feels like it’s been frozen in time. It is also a place where locals have stopped being surprised by strange lights.
If you talk to the people living near the Irazú Volcano, they describe "bolas de fuego" (fireballs) that move with an intelligence that defies physics. These aren't meteors. Meteors don't pull 90-degree turns at 2,000 miles per hour.
Ricardo Vílchez is a name you’ll hear a lot if you dig into this. He’s spent decades documenting these events. He’s not a guy looking for fame; he’s a researcher who realized that the topography of Costa Rica—specifically the volcanic chains—seems to act like a magnet for these objects.
There’s a theory among some local researchers that the high mineral content in the volcanic soil or the electromagnetic signatures of the mountains themselves might be the draw. Is it true? Who knows. But the sheer volume of reports from the "Zona de los Santos" and the Cartago highlands makes it hard to ignore.
The 2016 Turrialba "Eruption" Sighting
In 2016, the Turrialba Volcano was having a bit of a moment, spewing ash and keeping the Central Valley on edge. During a live-streamed monitoring of the crater, a glowing object was caught on camera zipping past the eruption at a speed that would have shredded a commercial drone.
The footage went viral. Skeptics pointed to birds or insects catching the light of the glow. But the trajectory was perfectly linear, and the luminosity was consistent even when the object moved behind the plumes of volcanic ash. It’s these kinds of Costa Rica UFO sightings that keep the local news stations busy and the skeptics scratching their heads.
What Most People Get Wrong About Sightings Here
People usually think UFO hunters are all wearing tinfoil hats and living in trailers. In Costa Rica, the most credible reports often come from the most "normal" people.

We’re talking about:
- Commercial pilots flying the San José to Panama City route.
- Coast Guard officers patrolling the Osa Peninsula.
- Farmers who have lived on the same patch of land for 80 years and know every star in the sky.
When a farmer in San Carlos tells you he saw a craft land in his pasture and leave charred circles in the grass, he isn't trying to get on Netflix. He’s usually annoyed that his cows are spooked and won't produce milk for three days.
The "UFO Bridge" in Guápiles
There is a specific stretch of highway near Guápiles that locals jokingly (or maybe not so jokingly) refer to as a transit point. Multiple drivers have reported their car engines dying simultaneously while a large, silent object passed overhead.
Is it "aliens"? Maybe. Is it some kind of atmospheric anomaly we don't understand yet? Also possible. But the consistency of the descriptions—the silence of the craft, the metallic sheen, and the sudden drop in ambient temperature—is what makes the Costa Rica UFO sightings so compelling.
The Role of the Juan Santamaría Airport
Even the main international airport isn't immune. There have been several instances where radar operators have picked up "unidentified traffic" that appears out of nowhere and disappears just as fast.
In many cases, these objects don't have transponders. They don't respond to radio hail. They just exist in the airspace for a few minutes and then "blink" out. While the Civil Aviation Authority (DGAC) is generally pretty tight-lipped about these things—mostly because they don't want to freak out tourists—individual controllers have been much more vocal after they retire.
Why Does This Matter for You?
If you’re traveling to Costa Rica, you’re probably looking at the ground for snakes or the trees for monkeys. Maybe look up once in a while.

The best places for "sky watching" aren't the bright lights of San José. You want to get to the high-altitude spots.
- The Talamanca Mountains: Massive, remote, and largely unexplored.
- The Guanacaste Coast: Specifically near Santa Cruz, where the lack of light pollution makes the sky look like a high-def movie.
- Arenal: The combination of water (the lake) and the volcano seems to be the "sweet spot" for sightings.
The Reality of the "Tic-Tac" in the Tropics
Ever since the Pentagon released those "Tic-Tac" videos a few years ago, the global conversation has shifted. It's not "crazy" to talk about this anymore.
In Costa Rica, the sightings often mirror those Navy videos. Objects that can move from the vacuum of space into the water without a splash (transmedium travel). Given that Costa Rica is flanked by two oceans and filled with deep, volcanic lakes, it’s a prime spot for this kind of activity.
Honestly, the most interesting part isn't the craft themselves. It’s how the locals react. There’s a weirdly calm acceptance of it. People see something strange, they talk about it at the pulpería (corner store) the next morning, and then they go back to picking coffee or guiding tours. It’s just part of the landscape.
Practical Steps for the Curious
If you’re genuinely interested in the history of Costa Rica UFO sightings, you shouldn't just Google it. You need to talk to people.
- Visit the National Museum: While they don't have a "UFO Wing," looking at the Diquis Stone Spheres will give you a sense of the ancient mysteries that still baffle researchers in this country. Some people think there's a connection between the spheres and celestial alignments.
- Talk to the Older Generation: If you find yourself in a rural town like Zarcero or Orosi, ask the older folks about "luces en el cielo." They have stories that haven't made it to the internet yet.
- Use the Right Apps: If you see something, use a flight tracker app immediately. If there’s no transponder signal but you’re looking at a physical object, you’ve got something interesting.
- Document Properly: If you’re lucky enough to catch something on your phone, don't zoom in until you've established the surroundings. We need reference points (trees, buildings, mountains) to determine size and speed.
Costa Rica is a place where the line between nature and the supernatural is incredibly thin. Whether it’s the legend of the Cadejo or a metallic disc hovering over Lake Cote, the country demands that you keep an open mind.
The evidence from 1971 still stands as a challenge to every skeptic. We have the photo. We have the measurements. We just don't have the answers. So, next time you’re sitting on a beach in Nosara or hiking the base of a volcano, don't just look for the "Pura Vida." Look for the "Pura Curiosidad."
The skies here are much busier than we think.
Insights for the Modern Observer
- The Science: The Lake Cote photo was analyzed by Dr. Richard Haines, a former NASA scientist. His conclusion? The object was a real, physical, three-dimensional craft.
- The Geography: Sightings are disproportionately high near the "Volcanic Central Range."
- The Culture: Unlike the US, where UFOs are often linked to government cover-ups, in Costa Rica, they are seen more as a natural, albeit mysterious, part of the environment.
- The Frequency: Reports tend to spike during the dry season (December to April), though this is likely just because the skies are clearer and more people are outside.
Keep your eyes on the horizon. The next major piece of evidence for the global UAP phenomenon might just come from a small coffee farm in the Central Valley.
