forbidden island

Imagine a world where isolated islands remain untouched by the modern traveler, a world where stepping onto these forbidden islands could mean danger, legal repercussions, or worse. 

These islands, scattered across the globe, have captured our curiosity and fascination for decades. 

In this article, we embark on a virtual journey to explore the top 10 most forbidden islands from around the world, unveiling the mysteries and the reasons why these enigmatic places remain off-limits to visitors.

1. North Sentinel Island, Andaman Islands

Forbidden by Nature and Inhabitants

Our journey begins in the Andaman Islands, an archipelago in the Bay of Bengal. Nestled among its emerald gems is North Sentinel Island, known for its isolation and its inhabitants, the Sentinelese people.

The Sentinelese have remained isolated for thousands of years, shunning contact with the outside world.

Any attempt to approach the island is met with hostility, as the Sentinelese are fiercely protective of their way of life.

This hostility, combined with the risk of introducing foreign diseases to the tribe, has led to strict restrictions on visiting North Sentinel Island.

The history of North Sentinel Island is shrouded in mystery, with the Sentinalese people’s isolation dating back thousands of years.

Historical records suggest that attempts at contact were made by explorers and traders, but the Sentinalese vehemently resisted outsiders.

The tragic event of the 19th-century British naval officer Maurice Vidal Portman kidnapping several Sentinalese individuals further intensified the isolation.

This dark episode has contributed to the island’s forbidden status, emphasizing the importance of respecting the Sentinalese desire for seclusion and safeguarding their cultural heritage.

2. Niihau, Hawaii

The Forbidden Isle

Niihau, also known as the “Forbidden Isle,” is a privately owned island in the Hawaiian archipelago.

The Robinson family, who owns Niihau, has kept it closed to the public for over 150 years, allowing only limited access to residents and invited guests.

The island serves as a sanctuary for native Hawaiian culture and traditions, and its isolation is a means of preserving the way of life of its inhabitants.

Niihau’s history is interwoven with the preservation of Hawaiian culture.

During World War II, a Japanese pilot crash-landed on Niihau after the attack on Pearl Harbor.

The islanders’ decision to support the U.S. military in capturing the pilot underscored their commitment to protecting their homeland.

This event, coupled with the Robinson family’s dedication to maintaining the island’s isolation, has played a crucial role in defining Niihau as the “Forbidden Isle.”

Preserving Niihau’s historical ties to Hawaiian resilience and loyalty remains paramount.

A Forgotten French Outpost

Ile Saint-Paul, a tiny volcanic island in the southern Indian Ocean, is a forgotten French outpost.

It was once used for sealing and whaling, but today it remains uninhabited.

The reason for its isolation lies in its remoteness and harsh climate, making it an inhospitable place for visitors.

The French government also restricts access to protect the fragile ecosystem of the island.

Once a hub for sealing and whaling activities, Ile Saint-Paul now stands forgotten in the southern Indian Ocean.

The Haunted Island

Poveglia, a small island in the Venetian Lagoon, has a dark and chilling history.

It was once used as a quarantine station during outbreaks of the plague, and it is rumored to be haunted by the restless souls of those who died on its shores.

Due to its grim past and the reported paranormal activity, the Italian government has banned public access to Poveglia.

A Toxic Legacy

Known by its ominous nickname, Poison Gas Island, this Japanese island is a place tainted by its dark history.

During World War II, the Japanese military conducted chemical warfare experiments on the island, resulting in lethal contamination.

Forbidden islands worldwide harbor delicate ecosystems that have evolved in isolation, showcasing unique biodiversity and environmental adaptations.

Preserving these ecosystems is paramount to maintaining the islands’ ecological integrity and safeguarding the rare species that call them home.

Key Considerations:

This approach recognizes the role of indigenous knowledge and practices in maintaining the delicate balance of island ecosystems.
  5. Establishing Marine Protected Areas: Some forbidden islands are surrounded by marine environments that require protection. The establishment of marine protected areas (MPAs), guided by international agreements like the Convention on Biological Diversity, contributes to safeguarding the marine ecosystems around these islands.
