There are few moments underwater that make a diver completely forget where they are.
You can be swimming along a reef, looking at ordinary tropical fish, when suddenly the light above you disappears.
You look up.
And there is a manta ray.
Not a little ray hiding in the sand, but a gigantic animal gliding silently overhead, its enormous wings moving with slow, effortless strokes. For a few seconds it can feel less like watching a fish and more like watching a bird fly through another world.
And Panama is one of the places where you can experience exactly that.
Panama's Pacific coast is manta country
If you want to see manta rays in Panama, your attention should be directed toward the Pacific coast, particularly the waters around Coiba National Park and the Gulf of Chiriquí.
The official Panama tourism authority specifically lists giant manta rays among the spectacular marine animals that can be encountered around Coiba. The park lies along an important marine corridor of the Eastern Tropical Pacific, linking the waters of Panama with other major marine ecosystems farther west and south.
Divers around Coiba have been reporting remarkable manta encounters for years. National Geographic famously described diving around Coiba among hundreds of manta rays, with the animals feeding on plankton rich waters.
And that tells you something important about Panama.
You don't necessarily have to travel to some remote island in the middle of the Pacific to encounter one of the ocean's great giants.
You can find them here.
They are enormous
The giant oceanic manta ray, scientifically known as Mobula birostris, is the largest ray in the world.
And when I say large, I mean ridiculously large.
A giant manta can reach a wingspan of around 7 metres, or approximately 23 feet. NOAA lists individuals reaching up to 26 feet across and weighing thousands of pounds.
Imagine standing in a small room with a ceiling several metres above your head.
Now imagine something that wide swimming directly over you.
That's a manta.
Yet despite its extraordinary size, a manta does not look threatening. There is something almost peaceful about the animal. Its huge pectoral fins curve gracefully through the water and its entire body seems designed for effortless movement.
It doesn't need to chase its food.
It simply flies through the ocean.
Mantas don't eat people
This is perhaps the first question from anyone who has never encountered one.
Are they dangerous?
No. Manta rays are filter feeders.
They are not hunting sharks or seals. They are not interested in divers. They don't have the aggressive feeding behaviour that people sometimes associate with large marine predators.
Instead, they swim through plankton rich water with their enormous mouths open, filtering tiny organisms from the sea.
That creates one of the most extraordinary underwater spectacles imaginable.
A huge animal weighing thousands of pounds can be swimming directly toward you with its mouth wide open, and yet you have absolutely nothing to fear.
It is basically a gigantic underwater vacuum cleaner with wings.
Why do mantas come to Coiba?
Food.
The Pacific waters around Panama can be exceptionally productive, particularly where currents and seasonal oceanographic conditions concentrate plankton.
And wherever there is an enormous amount of plankton, animals that specialize in eating plankton have a very good reason to show up.
Mantas are highly mobile animals and can travel long distances in search of food. Their movements are often associated with plankton availability and productive areas of the ocean.
Coiba's location is particularly fascinating because it sits within the Eastern Tropical Pacific marine corridor.
This is not just a local patch of ocean.
It is part of a much larger underwater highway used by some of the Pacific's most spectacular animals.
That helps explain why the waters around Coiba can produce such an extraordinary collection of marine life, including manta rays, whale sharks, hammerhead sharks, turtles and huge schools of fish.
Sometimes the water becomes a manta highway
One of the most spectacular things about manta encounters is that you may see a single animal.
Or you may see several.
Or, under the right conditions, you can suddenly find yourself beneath a procession of enormous rays.
A National Geographic account of diving at Coiba described hundreds of manta rays moving overhead while feeding on plankton.
That must be one of those underwater experiences where your brain needs several seconds to understand what your eyes are telling it.
One manta is impressive.
A group of giant mantas passing overhead is something else entirely.
The rays move almost like birds in formation, although there is no frantic flapping. Their movements are slow, controlled and remarkably elegant.
They appear to fly.
They have individual fingerprints
Here's a particularly fascinating manta fact.
You can sometimes identify individual manta rays by the markings on their undersides.
The pattern of spots and coloration on the belly can be unique to an individual animal, allowing researchers and experienced observers to recognize particular mantas when they return to an area.
So a manta isn't necessarily just "a manta."
With enough research, it can become that manta.
Researchers and citizen scientists can photograph animals from below and compare their markings over time. This helps build knowledge about movements, populations and behaviour.
Imagine seeing the same enormous ray on different dives and realizing that you've met before.
The ocean suddenly becomes a little smaller.
Mantas have passengers
Look closely at a manta and you may notice that it isn't always travelling alone.
Small fish can accompany large marine animals, sometimes gaining protection, food opportunities or simply a free ride.
Divers occasionally see fish travelling close to a manta's body or around its head. Dive operators around Coiba have documented these relationships during manta encounters.
It is one of those wonderfully strange scenes that reminds you how different the rules of the ocean are.
Imagine being a tiny fish and deciding that the safest place to travel is beside a seven metre wide animal.
Apparently, the fish have done the mathematics.
Mantas are not stingrays
Another common misunderstanding is that people see a large ray and immediately think of a stingray.
Mantas are very different animals.
The familiar stingray spends much of its time close to the bottom and many species bury themselves in sand. Mantas are open water specialists, built for cruising through the water column.
And unlike stingrays, manta rays do not have the intimidating defensive tail spine that people associate with many other rays.
Their enormous size can make them look intimidating, but their behaviour around divers is generally remarkably calm.
The best way to experience one is simply to remain still and let the animal decide where it wants to go.
Don't chase the giant
This is important.
Seeing a manta is exciting.
Trying to chase one around the ocean with a GoPro is not.
Mantas are wild animals, and the best encounters usually happen when the diver behaves like a quiet observer rather than an underwater paparazzi photographer.
Don't grab them.
Don't touch them.
Don't block their path.
Don't swim directly toward them.
If a manta wants to pass overhead, let it.
If it wants to disappear into the blue, let it disappear.
Sometimes the most memorable wildlife encounters are the ones where you barely do anything at all.
You simply stop.
And watch.
The conservation story is serious
Manta rays may look invincible because of their size, but they are vulnerable animals.
The giant manta ray is classified as Vulnerable, and international conservation authorities recognize serious threats from fishing, bycatch and international trade.
Their biology doesn't help them recover quickly. They grow slowly and reproduce relatively slowly compared with many smaller fish.
That means losing large numbers of adults can have serious consequences for populations.
Panama has also strengthened protections around sharks and rays. MiAMBIENTE announced that from January 1, 2026, Panama maintains a zero export quota for CITES listed shark and ray species, aimed at reducing pressure from international trade and improving conservation and monitoring.
And Coiba is an extraordinarily important place for that conservation story.
The national park protects one of the largest coral reef systems in the Eastern Tropical Pacific, along with an enormous surrounding marine environment.
Coiba is much more than a manta destination
This is what makes a trip to Coiba so fascinating.
You don't go there simply hoping to see one particular animal.
You enter an ecosystem where almost anything can happen.
A dive might produce manta rays.
Another could produce hammerheads.
Another might bring turtles.
Whale sharks can also pass through the region.
During certain months, humpback whales migrate through Panamanian Pacific waters as well. PADI notes that whale activity occurs from approximately July through October, adding another enormous animal to an already impressive list of possible encounters.
So you could theoretically spend a few days around Panama's Pacific coast and find yourself looking at a manta underwater, hearing whales from the boat and watching dolphins on the way back.
That's a pretty serious wildlife vacation.
And then the manta disappears
Perhaps the most beautiful thing about seeing a manta is how quickly the encounter can vanish.
You are watching this enormous animal glide above you.
Then it turns.
Its wings change angle.
The sunlight catches its body.
And suddenly it is moving away into the blue.
There is no dramatic ending.
No roar.
No splash.
No soundtrack.
It simply becomes smaller and smaller until eventually there is nothing left but blue water.
And that is exactly why seeing one in the wild is so special.
You haven't visited an aquarium.
You haven't watched a trained animal perform.
You haven't been guaranteed a show.
For a few minutes, you happened to share the ocean with one of the largest and most graceful animals on Earth.
Then it continued on its journey.
The best part about manta rays in Panama
Panama has a strange habit of hiding some of its most spectacular wildlife in places that aren't necessarily on every traveler's itinerary.
People come for beaches.
They come for surfing.
They come for tropical islands.
They come for jungle.
And then, if they venture farther into the Pacific, they discover that underneath those waves is another Panama entirely.
A Panama of enormous schools of fish, sharks, turtles, whales and giant manta rays.
The waters around Coiba are one of the places where that hidden world becomes particularly spectacular. The official tourism authority itself lists giant manta rays among the major wildlife attractions of the park.
So if you're a diver visiting Panama, don't just look at the ocean from the beach.
Look down.
There may be something enormous flying beneath you.
