Penal Colony of Isla Coiba - Coiba National Park
The Prison of Isla Coiba
Long before Coiba became internationally known for sharks, coral reefs and extraordinary biodiversity, the island was known throughout Panama for something very different: its prison.
From 1919 until 2004, Isla Coiba served as a penal colony.
For generations of Panamanians, the name Coiba evoked isolation, punishment, fear and stories of people who were sent away and never returned.
The prison housed ordinary criminal offenders as well as political detainees during some of the most turbulent periods of Panama’s twentieth-century history.
Today the penal colony is closed, its surviving structures deteriorating beneath the tropical sun and surrounding forest.
But the prison remains an essential part of understanding Coiba.
Why Build a Prison on Coiba?
Isolation made Isla Coiba an obvious location for a penal colony.
The island lies off Panama’s Pacific coast, separated from the mainland by open ocean.
Before modern communications and fast boats, reaching Coiba was difficult.
Escaping from it was even more difficult.
The surrounding Pacific created a natural barrier, while the island’s tropical forest, rivers and rugged terrain made traveling across Coiba itself challenging.
In 1919, Panama established a penal colony on the island.
It would remain in operation for the next 85 years.
A Penal Colony, Not Just a Prison Building
It is easy to imagine Coiba as a single enormous prison surrounded by walls.
That isn’t how much of the penal colony operated.
Prisoners were distributed among camps in different parts of the island, with a central station serving as the administrative heart of the system.
Some inmates lived in conventional cell blocks, while others were housed in more basic camps associated with agricultural and livestock operations.
The ocean itself provided much of the security.
There was little reason to construct an enormous wall around an island from which escape required crossing miles of Pacific water.
Life in the Prison Colony
Conditions on Coiba varied over the prison’s long history, but the island developed a fearsome reputation.
Prisoners performed agricultural and other labor, producing food and maintaining operations within the colony.
Farms, livestock areas, roads, camps and administrative buildings were established in portions of the island.
The intention was partly to make the remote penal colony capable of supporting itself.
Coiba’s geography, however, made almost everything difficult.
Food, equipment, personnel and prisoners had to travel by sea, while the tropical climate constantly attacked buildings, machinery and roads.
Prison Labor and Agriculture
Agriculture was an important part of life at Coiba.
Prisoners worked land around the camps, raised livestock and cultivated crops.
At various times, these agricultural activities were intended both to feed the penal population and to make productive use of the island.
There were even broader ambitions during parts of Coiba’s history to develop or eventually colonize areas of the island.
Those plans never transformed Coiba into a major civilian settlement.
The difficulty and expense of transporting goods between the island and mainland Panama helped keep development limited.
An Island Feared by Panama
Over the decades, Coiba became deeply embedded in Panamanian popular imagination.
Being sentenced to Coiba meant being removed not simply from society, but from the mainland itself.
Stories circulated about violence between prisoners, abuse by guards, dangerous wildlife and people who disappeared on the island.
Some stories were documented.
Others became difficult to separate from rumor and legend.
Together they created a reputation powerful enough that many ordinary Panamanians wanted nothing to do with Coiba.
Coiba During Panama’s Military Regime
The darkest period in the prison’s history is closely connected with Panama’s years of military rule.
After the 1968 military coup, Panama was governed for more than two decades under a military regime associated first with General Omar Torrijos and later with General Manuel Antonio Noriega.
During this period, political opponents, dissidents and members of the security forces who came into conflict with the regime were among those imprisoned.
Coiba became associated not only with criminal punishment but with political repression.
Political Prisoners
Accounts from the military period describe political detainees being sent to Coiba alongside convicted criminals.
The island’s remoteness made outside scrutiny difficult.
Families, attorneys and human-rights observers could not simply arrive unannounced at a prison located many miles offshore.
This isolation contributed greatly to Coiba’s reputation as a place where abuses could occur far from public view.
For opponents of the regime, the threat of being sent to Coiba carried meaning far beyond an ordinary prison sentence.
Los Desaparecidos
Panama’s military period is also remembered for los desaparecidos—the disappeared: people detained or abducted for political reasons whose fate was concealed or never adequately explained.
Coiba became linked in public memory with those disappearances.
Stories have long circulated claiming that political prisoners were secretly killed on the island and buried in unmarked graves.
Even more disturbing stories claimed that bodies were disposed of in the surrounding ocean.
These allegations form an important part of Coiba’s historical memory, but many of the most sensational versions have never been conclusively proven.
After the fall of Manuel Noriega, searches of the island did not resolve all of the rumors concerning supposed mass graves.
The absence of definitive evidence should not diminish the documented reality of political repression and disappearance in Panama, but it is important to distinguish that history from stories that remain unverified.
The Fall of Manuel Noriega
In December 1989, the United States invaded Panama in an operation that brought Manuel Noriega’s rule to an end.
Coiba’s prison suddenly entered another period of transition.
U.S. personnel who reached the island investigated reports about political prisoners, weapons and possible graves.
Contemporary reporting described extremely poor conditions inside parts of the prison.
But investigators did not confirm many of the dramatic rumors that had accumulated around the island during the dictatorship.
The uncertainty surrounding some of those stories remains part of Coiba’s complicated history.
The Prison Continued After the Dictatorship
Noriega’s fall did not immediately end the penal colony.
Coiba continued operating as a prison during Panama’s return to democratic government.
The inmate population increasingly consisted of people convicted of ordinary criminal offenses rather than political detainees.
Panama’s prison system also continued using Coiba to relieve pressure on overcrowded mainland facilities.
Plans to close the island prison were discussed repeatedly, but the institution remained active into the twenty-first century.
Harsh Conditions Continued
The end of military government did not transform Coiba into a comfortable prison.
Human-rights reporting during the 1990s continued to describe conditions on the island as harsh and dangerous.
The remote location complicated medical care, security, supplies and oversight.
Violence among prisoners remained a serious problem.
One particularly disturbing episode occurred in 1998.
The Violence of 1998
In January 1998, a confrontation involving rival prisoner groups resulted in several brutal killings.
Contemporary U.S. State Department human-rights reporting documented the deaths and noted continuing investigations into additional killings discovered that year.
The incident demonstrated that even near the end of its existence, Coiba remained an extraordinarily difficult environment in which to operate a prison.
It also strengthened arguments that Panama needed to move prisoners into more manageable mainland facilities.
The Beginning of the End
By the 1990s, Coiba was living two very different lives at the same time.
Part of the island remained a functioning penal colony.
But scientists and conservationists were increasingly recognizing the extraordinary ecological importance of the forests and surrounding marine environment.
In 1991, Panama established Coiba National Park, meaning that for more than a decade the national park and the penal colony existed simultaneously.
That unusual overlap finally ended in 2004.
The Prison Closes
The Coiba penal colony permanently closed in August 2004.
Remaining prisoners were transferred to other facilities on the mainland.
After 85 years, Isla Coiba was no longer a prison island.
The timing was significant.
Panama enacted Law 44 of July 26, 2004, strengthening the legal framework for Coiba National Park and establishing its Special Zone of Marine Protection.
One year later, Coiba National Park and its Special Zone of Marine Protection were inscribed on the UNESCO World Heritage List.
The island’s international identity was changing dramatically.
From Prison Island to World Heritage Site
Within the span of only a few years, Coiba went from housing prisoners to being internationally recognized as one of the world’s important natural protected areas.
It sounds like an extraordinary reversal.
In reality, the two stories are connected.
Coiba had become environmentally important partly because so much of the island had remained undeveloped during the prison era.
The penal colony affected particular areas through farming, livestock, buildings, roads and settlements.
But large portions of the island remained forested.
Fear and restricted access discouraged the kind of widespread civilian settlement, logging, tourism development and agriculture that transformed many other tropical landscapes.
The Accidental Conservation Effect
This produces one of the great contradictions in Coiba’s history.
An institution associated with imprisonment and suffering inadvertently helped isolate one of Panama’s most important natural ecosystems from development.
That does not mean the prison should be credited as a conservation project.
It wasn’t.
Forest survived partly as an unintended consequence of restricted access and isolation.
Meanwhile, agricultural operations and introduced livestock caused ecological impacts in areas used by the penal colony.
Coiba’s conservation story therefore cannot be reduced to the simple idea that “the prison saved the rainforest.”
The reality is more complicated—and more interesting.
What Happened to the Prison Buildings?
After the penal colony closed, many of its structures were abandoned.
Tropical weather began working on them immediately.
Salt air corrodes metal. Humidity damages concrete and wood. Vegetation grows through abandoned spaces.
Over time, sections of the former penal complex have deteriorated significantly.
Cell blocks, administrative buildings and other remnants remain evidence of the island’s past, but they should be understood as historic ruins rather than a preserved modern museum complex.
The Central Station
The best-known remnants are associated with the former central station of the penal colony.
This area contained administrative and prison facilities and became the location most visitors historically associated with “the Coiba prison.”
Surviving structures provide an impression of the institutional side of the colony that is difficult to understand from photographs alone.
But the central station represents only one part of an operation that once extended through numerous camps elsewhere on the island.
The Prison Camps
Smaller camps were established in different locations around Isla Coiba.
These allowed prisoners to work agricultural areas and perform other tasks without traveling constantly back to the central station.
Some structures were comparatively permanent, while others were simple wooden or metal-roofed buildings suited to a remote tropical outpost.
Many have deteriorated, disappeared beneath vegetation or become difficult to access.
The jungle is gradually erasing the physical footprint of the penal colony.
Nature Reclaims the Prison
Few places demonstrate tropical regeneration as dramatically as an abandoned building in Coiba.
Plants push through cracks. Vines climb walls. Insects and small animals occupy spaces once used by people.
The boundary between ruin and forest becomes less distinct with every passing year.
This process gives the old prison an atmosphere unlike a conventional historic site.
It is not frozen in time.
It is actively being reclaimed by the ecosystem that surrounds it.
Remembering the People
The prison ruins can easily become visually fascinating—crumbling buildings surrounded by tropical forest make compelling photographs.
But they represent real human experiences.
Thousands of prisoners passed through the penal colony during its 85-year history.
Some were violent criminals.
Some were political prisoners.
Some suffered abuse.
Some died on the island.
And some families were left without clear answers about what happened to people who disappeared during Panama’s years of military rule.
Visiting the prison should therefore involve remembrance as well as curiosity.
History Without Sensationalism
Coiba has accumulated legends worthy of a novel.
Stories describe prisoners disappearing into the jungle, impossible escapes, shark-filled waters, secret executions and hidden graves.
Some accounts have factual foundations. Others have been repeated so often that separating evidence from folklore is difficult.
The island’s documented history is powerful enough without embellishment.
Political imprisonment, forced isolation, brutal prison conditions and unresolved disappearances are serious historical subjects.
They deserve careful treatment rather than turning Coiba into a tropical ghost story.
Was Coiba Panama’s Devil’s Island?
Coiba has often been compared with Devil’s Island, the notorious French penal colony associated with French Guiana.
The comparison is understandable.
Both became symbols of remote island imprisonment, tropical hardship and apparently impossible escape.
But Coiba had its own history shaped by Panama’s political development, criminal-justice system and military regime.
Calling it “Panama’s Devil’s Island” communicates something about its reputation, but understanding Coiba requires looking beyond the nickname.
Could Prisoners Escape?
The lack of conventional prison walls created the impression that inmates were free to walk away.
The reality was that geography served as the wall.
An escapee would first have to reach a suitable coastline, find or construct some means of crossing open Pacific water, navigate toward the mainland and avoid recapture.
The surrounding ocean, distance and isolation made escape extraordinarily difficult.
Stories of attempted escapes became another important part of prison folklore.
Sharks, Crocodiles and Prison Legends
Coiba’s abundant wildlife also became woven into prison stories.
Sharks inhabit the surrounding Pacific, and American crocodiles occur around portions of the island.
Over time, these animals became part of tales describing why escape was impossible or what supposedly happened to prisoners who disappeared.
Wildlife undoubtedly added psychological power to the island’s isolation.
But stories portraying sharks or crocodiles as deliberate components of the prison’s security system should be treated as folklore rather than historical fact.
Scientific Expeditions During the Prison Era
Although access to Coiba was tightly controlled, scientists occasionally visited the island while the penal colony was still operating.
One notable visitor was American ornithologist Alexander Wetmore, who served as Secretary of the Smithsonian Institution.
Wetmore conducted ornithological research in Panama and visited Coiba during the 1950s.
Historical photographs from his expedition show convicts arriving on the island and document the unusual overlap between prison operations and scientific exploration.
Some prisoners even worked as laborers assisting scientific expeditions.
Scientists Discover an Extraordinary Island
Researchers gradually recognized that Coiba’s isolation had created something scientifically exceptional.
Plants and animals had developed distinctive island populations, while extensive forest remained compared with many mainland areas.
Marine scientists discovered equally remarkable biodiversity in the surrounding Pacific.
The same remoteness that made Coiba useful as a prison had also created an extraordinary natural laboratory.
Eventually, that scientific importance would help define Coiba’s future much more strongly than its prison.
The Prison and Coiba’s Wildlife
It would be inaccurate to say that the penal colony had no environmental impact.
Prison operations required land.
Forest was cleared for camps, farming and livestock. Non-native animals were introduced. Roads and buildings altered portions of the landscape.
But the impact was geographically limited compared with the scale of Isla Coiba.
Outside the developed prison areas, extensive forest remained relatively free from permanent settlement.
After the prison closed, some formerly used landscapes began regenerating naturally while conservation managers addressed the legacy of introduced animals and abandoned infrastructure.
From Fear to Curiosity
For older generations of Panamanians, Coiba was somewhere to avoid.
Today, travelers cross the Pacific specifically because they want to see it.
Scuba divers come for sharks and enormous schools of fish. Snorkelers explore shallow reefs. Bird watchers search for endemic species. Scientists investigate evolutionary processes and marine connectivity.
The transformation in public perception within a single generation is remarkable.
But the newer image of Coiba as paradise should not erase the older one.
Two Histories on One Island
Coiba contains two stories that initially seem incompatible.
One is a story of incarceration, political repression and human suffering.
The other is a story of biodiversity, conservation and scientific discovery.
They occupy the same landscape.
The prison influenced the environment, and the island’s environment influenced the prison.
Neither story is complete without the other.
Can You Visit the Old Prison?
Parts of the former penal colony have historically been included in authorized visitor itineraries.
However, access should never be assumed.
The condition of historic structures, construction work, safety requirements and park-management decisions can result in temporary or longer-term restrictions.
Visitors specifically interested in prison history should confirm current access with MiAmbiente and their authorized tour operator before traveling to Coiba.
Do not choose a tour solely because an outdated itinerary promises access to the old penal complex.
Historic Ruins Are Not an Adventure Playground
Abandoned buildings can contain unstable walls, damaged floors, exposed metal and other hazards.
The tropical climate accelerates deterioration.
Visitors should enter only areas authorized by park personnel and guides and should never climb on or remove material from historic structures.
Graffiti and souvenir collecting permanently damage what remains of the site.
The ruins are part of Panama’s cultural history and should be treated accordingly.
The Aeronaval Presence
The area around the former central station is also associated with facilities used by Panama’s Servicio Nacional Aeronaval (SENAN).
SENAN performs security, maritime surveillance and other national responsibilities in the Coiba region.
Visitors should therefore understand that not everything near the former prison is an abandoned historic structure or tourism facility.
Operational government areas may be restricted and should be entered only with authorization.
The Prison Is Part of the Conservation Story
It may seem strange to include prison history on a website devoted largely to nature.
But removing it would make Coiba harder to understand.
The island’s unusual twentieth-century isolation affected patterns of settlement and development.
That helped leave extensive habitat available when Panama eventually moved toward stronger conservation.
Today the former prison stands within the same national park that protects tropical forest, endemic wildlife and one of the most important marine ecosystems in the Tropical Eastern Pacific.

Coiba After 2004
The prison’s closure did not end Coiba’s story.
It changed its direction.
Law 44 strengthened protection of the national park and its marine environment in 2004.
UNESCO World Heritage recognition followed in 2005.
Scientific research expanded. Marine conservation became increasingly important. Tourism grew.
And an island once deliberately kept distant from ordinary society began welcoming visitors from around the world.
Preserving More Than Nature
Coiba deserves protection for more than its wildlife.
The island is also part of Panama’s historical heritage.
Its surviving prison structures, archaeological resources and memories associated with political repression tell stories that cannot be recreated once lost.
Conservation therefore has a broader meaning here.
It includes protecting forests and reefs, but it can also mean documenting and interpreting the human history embedded within the landscape.
A Difficult Legacy
There is something deeply uncomfortable about the fact that human suffering contributed indirectly to the preservation of a natural paradise.
That contradiction should not be ignored or turned into a cheerful conservation anecdote.
The people imprisoned on Coiba did not suffer so that future generations could have a national park.
Environmental preservation was an unintended consequence of isolation—not the purpose of the institution.
Remembering that distinction allows both sides of Coiba’s history to be treated with respect.
From a Place of Punishment to a Place of Protection
For 85 years, the Pacific surrounding Coiba helped keep prisoners in.
Today those same waters form part of a protected marine landscape intended to keep destructive pressures out.
The forest that once concealed prison camps now shelters endemic wildlife.
Boats that once carried prisoners across the Pacific have been replaced by vessels carrying scientists, park rangers and visitors.
The transformation is extraordinary.
But traces of the previous Coiba remain.
Walk among the surviving ruins and the island’s two identities become impossible to separate: one of Panama’s darkest historical landscapes standing within one of its greatest natural treasures.
