Illegal Islands That You Can’t Visit: Mysterious Places Off-Limits to the Public

Illegal Islands That You Can’t Visit

The allure of forbidden places has long captivated the human imagination, fueling a sense of mystery and fascination that is hard to resist. While most of the world’s exotic locales are open to visitors, there are some places that remain strictly off-limits, their secrets and stories hidden behind locked gates, barbed wire, and military patrols. These are the illegal islands, and remote outposts that are shrouded in mystery, danger, and controversy. In this blog post, we will explore some of the most intriguing and fascinating illegal islands in the world, from the volcanic wastelands of Surtsey Island in Iceland to the hostile shores of North Sentinel Island in India, and beyond. Join us on a journey into the heart of darkness, as we peel back the veil of secrecy and uncover the secrets of these forbidden isles.

Surtsey Island, Iceland

In the summer of 1963, something remarkable happened off the coast of Iceland. A massive volcanic eruption, triggered by a series of underwater earthquakes, gave birth to a new island in the middle of the North Atlantic Ocean. The island, which was later named Surtsey after the Norse god of fire, quickly captured the attention of the scientific community, which saw in it a unique opportunity to study the formation of a new ecosystem. But there was one catch: Surtsey was declared off-limits to all visitors, human or animal, for fear of disturbing the delicate balance of the new ecosystem.

For the past six decades, Surtsey Island has remained a pristine laboratory of nature, a place where scientists can study the complex interactions between geology, biology, and climate in a nearly pristine environment. Researchers have documented the arrival of a wide variety of plant and animal species on the island, from lichens and mosses to seabirds and insects. They have also observed the gradual erosion of the island’s volcanic rock, as the ceaseless action of wind and water slowly wears away at the surface. Today, Surtsey Island is recognized as a UNESCO World Heritage Site and a model for the study of island biogeography.

North Sentinel Island, India

Tucked away in the Bay of Bengal, North Sentinel Island is perhaps the most mysterious and enigmatic illegal island on Earth. The island, which is about the size of Manhattan, is home to the Sentinelese, an indigenous tribe that has lived in isolation for thousands of years. The Sentinelese are fiercely protective of their island, and they have shown hostility towards anyone who has attempted to visit them. Over the years, there have been numerous reports of fishermen, sailors, and even anthropologists being attacked by the island’s inhabitants.

The Indian government has declared North Sentinel Island off-limits to all visitors, citing concerns about the safety of both visitors and the indigenous population. In recent years, there has been growing interest in studying the Sentinelese and their way of life, but the dangers involved in such research make it extremely challenging. Despite the risks, the island continues to fascinate and intrigue researchers and adventurers alike, who see in it a window into a world that has remained largely unchanged for millennia.

Diego Garcia, British Indian Ocean Territory

Illegal Islands That You Can’t Visit

Located in the heart of the Indian Ocean, Diego Garcia is an illegal island that has been at the center of controversy and political intrigue for decades. The island was once home to a thriving population of indigenous people, who were forcibly removed by the British government in the 1960s to make way for a US military base. Today, the island is strictly off-limits to visitors, with access tightly controlled by the US military and the British government.

Diego Garcia has been the subject of numerous legal challenges over the years, with critics accusing the US and UK of violating international law and trampling on the rights of the island’s original inhabitants. The Chagos Islanders, as they are known, have been fighting for the right to return to their homeland for decades, but their efforts have been largely unsuccessful. In recent years, the issue has gained renewed attention, with several countries and human rights organizations calling for the repatriation of the Chagos Islanders and the dismantling of the military base.

The controversy surrounding Diego Garcia has only added to its mystique, as stories of secret military operations, covert spying, and extrajudicial detentions have swirled around the island for years. Despite the strict security measures in place, the island continues to attract curiosity and speculation, with many people wondering what exactly goes on behind the barbed wire and guarded gates.

Hashima Island, Japan

Located off the coast of Nagasaki, Hashima Island, also known as Gunkanjima or “Battleship Island,” is one of Japan’s most notorious illegal islands. Once a bustling coal-mining town, the island was abandoned in the 1970s when the coal industry declined. Today, the island is a haunting reminder of a bygone era, its towering concrete buildings and decaying infrastructure a testament to the hopes and dreams of a bygone era.

Despite its abandonment, Hashima Island remains a popular destination for urban explorers and photographers, drawn to its eerie atmosphere and post-apocalyptic aesthetics. However, the island is also highly dangerous, with the decaying buildings and unstable infrastructure posing a serious risk to visitors. As a result, the island is officially off-limits to the public, with access restricted to authorized personnel only.

Efforts have been made to preserve and restore the island, with UNESCO recognizing it as a World Heritage Site in 2015. However, controversy remains over the use of the island, with some advocating for its complete preservation as a historical site and others calling for its redevelopment as a tourist destination. Whatever the future holds for Hashima Island, its past is a haunting reminder of the fragility of human endeavors and the relentless march of time.

Poveglia Island, Italy

Just off the coast of Venice, Poveglia Island is a place of dark history and sinister legends. For centuries, the island was used as a quarantine station for ships arriving in Venice, with suspected plague victims and other sick individuals sent there to be isolated and treated. However, the island’s reputation took a darker turn in the 20th century, when it was turned into an asylum for the mentally ill.

The conditions on Poveglia Island were notoriously brutal, with patients subjected to inhumane treatment and experiments. Over the years, countless people died on the island, and their remains are said to still haunt the abandoned buildings to this day. Today, the island is strictly off-limits to visitors, with the Italian government citing concerns over the structural integrity of the decaying buildings and the potential for contagion.

Despite the official ban, Poveglia Island remains a popular destination for ghost hunters and thrill-seekers, drawn to its reputation as one of the most haunted places in Italy. Its dark past and macabre legends have also made it the subject of countless books, films, and TV shows, cementing its status as a place of mystery and intrigue.

Clipperton Island, France

Located in the eastern Pacific Ocean, Clipperton Island is a remote and sparsely inhabited atoll that is considered a possession of France. The island was first claimed by France in 1858 and was used as a guano mine in the late 19th and early 20th centuries. Today, the island is home to a small French military detachment, but it is otherwise uninhabited.

Despite its relative obscurity, Clipperton Island has been the subject of controversy over the years, with neighboring countries such as Mexico and the United States questioning France’s claim to the island. The island is also known for its harsh conditions, with the lack of freshwater and extreme weather making it difficult for humans to survive there.

Today, Clipperton Island is a designated nature reserve, with efforts underway to protect its unique flora and fauna. However, the island remains strictly off-limits to visitors, with the French government citing concerns over the island’s fragile ecosystem and the potential for human disturbance. As a result, the island remains one of the most mysterious and enigmatic illegal islands in the world, a place of isolation and intrigue that is unlikely to be visited by outsiders anytime soon.

Palmyra Atoll, United States

Located in the Pacific Ocean, the Palmyra Atoll is a group of islets and reefs that is part of the United States’ Minor Outlying Islands. The atoll was first claimed by the United States in 1859 and was used as a naval air station during World War II. Today, the atoll is home to a diverse range of marine and bird species, with efforts underway to protect its fragile ecosystem.

Despite its natural beauty and ecological importance, the Palmyra Atoll is strictly off-limits to visitors, with access restricted to authorized personnel only. The reason for the ban is largely due to concerns over the island’s vulnerability to invasive species and the potential for human disturbance to disrupt the delicate balance of the atoll’s ecosystem.

While it may be frustrating for adventure-seekers and wildlife enthusiasts to be unable to visit the Palmyra Atoll, the strict regulations surrounding the island are a testament to the importance of preserving our natural world. By recognizing the value of these remote and vulnerable ecosystems, we can help to ensure that they remain healthy and thriving for generations to come.

Rockall, United Kingdom

Located in the North Atlantic, Rockall is a small, uninhabited islet that is part of the United Kingdom’s territory. The island is located over 400 kilometers off the coast of Scotland and is known for its remote and isolated location, as well as its challenging weather conditions.

Despite its relative obscurity, Rockall has been the subject of controversy over the years, with neighboring countries such as Ireland and Iceland questioning the legitimacy of the UK’s claim to the island. In addition, the island’s challenging terrain and harsh weather conditions make it virtually impossible for humans to survive there for any length of time.

As a result, Rockall is strictly off-limits to visitors, with access restricted to authorized personnel only. While this may be disappointing for adventurers and explorers, the island’s remoteness and inhospitable conditions are a testament to the power and majesty of the natural world, reminding us of our place in the grand scheme of things.


Illegal islands may be off-limits to visitors, but they remain a source of fascination and intrigue for many people around the world. From the pristine shores of Surtsey Island to the hostile terrain of North Sentinel Island and the contested grounds of Diego Garcia, these forbidden places offer a glimpse into the complex interplay of nature, history, and politics that shape our world. While their secrets may remain hidden for now, the allure of the illegal islands is unlikely to fade anytime soon.
