The 10 Most Dangerous Islands in the World


The top 10 Most Dangerous Islands in the World

These islands, filled with color and beauty, seemingly paradise, are to be avoided at all costs. Their threatening ways claim them to be some of the most dangerous places on earth. From the highly radioactive to dense populations of predators, these seven islands are the most dangerous places you shouldn’t step foot on.

The islands are specially meant for summer vacations and holiday seasons for greatest wanderlust. There are few islands, which are extremely unpredictable in terms of threats, and once trapped at these islands would certainly be impossible to escape. The islands may seem pretty good, but exploration is definitely a bad idea.

10.The Great Pacific Garbage Patch (Northern Pacific)

Details: – The Great Pacific garbage patch, also described as the Pacific trash vortex, is a gyre of marine debris particles in the central North Pacific Ocean discovered between 1985 and 1988. It is located roughly between 135°W to 155°W and 35°N and 42°N. The patch extends over an indeterminate area of widely varying range depending on the degree of plastic concentration used to define the affected area.

The patch is characterized by exceptionally high relative concentrations of pelagic plastics, chemical sludge, and other debris that have been trapped by the currents of the North Pacific Gyre. Its low density (4 particles per cubic meter) prevents detection by satellite photography, or even by casual boaters or divers in the area. It consists primarily of a small increase in suspended, often microscopic, particles in the upper water column.

9.Gruinard Island (Scotland)

Details: – Gruinard Island is a small, oval-shaped Scottish island approximately 2 kilometers (1.2 mi) long by 1 kilometer (0.62 mi) wide, located in Gruinard Bay, about halfway between Gairloch and Ullapool. At its closest point to the mainland, it is just over 1.1 kilometers (0.68 mi) offshore. The island was made dangerous for all mammals by experiments with the anthrax bacterium until it was decontaminated in the late 20th century.

The island was mentioned by Dean Munro who traveled the area in the mid 16th century. He wrote that it was Clan MacKenzie territory, was “full of woods”, (a striking comparison with its treelessness today) and that it was “guide for fostering of thieves and rebels


Details: – Miyake-Jima is an inhabited volcanic island in the Izu archipelago in the Philippine Sea approximately 180 kilometers southeast of Honshu, Japan. As with the other islands in the Izu Island group, Miyake-Jima forms part of the Fuji-Hakone-Izu National Park.

The island is administered by the Miyake Subprefecture of the Tokyo Metropolitan government. As of June 1, 2016, the population of the island was 2451. Miyake Village serves as the local government of the island and also encloses nearby tiny uninhabited Ōnoharajima west-southwest of Miyake-Jima.

7. Enewetak Atoll–Marshall Islands.

Details: – Enewetak Atoll is a large coral atoll of 40 islands in the Pacific Ocean and with its 850 people forms a legislative district of the Ralik Chain of the Marshall Islands. With a land area total less than 5.85 square kilometers, it’s not higher than 5 meters and surrounds a deep central lagoon, 80 kilometers in circumference. It is the second-westernmost atoll of the Ralik Chain and is 305 kilometers west from Bikini Atoll.

Nuclear testing by the US totaling more than 30 megatons of TNT took place during the cold war; in 1977–1980, a concrete dome (the Runit Dome) was built on Runit Island to deposit radioactive soil and debris.

The Runit Dome is deteriorating and could be breached by a typhoon, though the sediments in the lagoon are even more radioactive than those which are contained.

6.Saba Island (Netherlands)

Details: – Saba is a Caribbean island and the smallest special municipality of the Netherlands. It consists largely of the potentially active volcano Mount Scenery, at 887 meters the highest point of the entire Netherlands.

Saba has a land area of 13 square kilometers. As of January 2013, the population was 1,991 inhabitants, with a population density of 150 inhabitants per square kilometer. Its towns and major settlements are The Bottom (the capital), Windwardside, Hell’s Gate and St. Johns.

5.Ramree Island–Burma.

Details: – Ramree Island is an island off the coast of Rakhine State, Burma. The area of the island is about 1,350 square kilometers and the main populated center is Ramree.

Saltwater crocodiles were still common in the Ramree Island region up and into the 1960s, but the region no longer supports a viable population of crocodiles, likely due to hide-hunting, and by the early 1980s evidence suggested only scattered individuals remained (Thorbjarnarson et al. 2006).

4.North Sentinel Island–Andaman Islands.

Details: – North Sentinel Island is one of the Andaman Islands, which includes South Sentinel Island, in the Bay of Bengal. It is home to the Sentinelese who, often violently, reject any contact with the outside world, and are among the last people worldwide to remain virtually untouched by modern civilization. As such only limited information about the island is known.

Nominally, the island belongs to the South Andaman administrative district, part of the Indian union territory of Andaman and Nicobar Islands. In practice, Indian authorities recognize the islanders’ desire to be left alone and restrict their role to remote monitoring.

3.Reunion Island–Indian Ocean.

Details: – Réunion is an island and region of France in the Indian Ocean, east of Madagascar and 175 kilometers (109 mi) southwest of Mauritius. As of 2014, it had a population of 844,994. It is the most prosperous island in the Indian Ocean, having the highest GDP per capita in the region.
The island has been inhabited since the 17th century when people from France, Madagascar, and Africa settled there. Slavery was abolished on 20 December 1848 (a date celebrated yearly on the island), after which indentured workers were brought from South India, among other places. The island became an overseas department of France in 1946.

As elsewhere in France, the official language is French. In addition, the majority of the region’s population speaks Réunion Creole.

Administratively, Réunion is one of the overseas departments of France. Like the other four overseas departments, it is also one of the 18 regions of France, with the modified status of the overseas region, and an integral part of the Republic with the same status as Metropolitan France. Réunion is an outermost region of the European Union and, as an overseas department of France, part of the Eurozone.

2.Poveglia Island (Italy)

Details: – Poveglia is a small island located between Venice and Lido in the Venetian Lagoon, northern Italy. A small canal divides the island into two separate parts.

Sometime after the island had become a quarantine station for ships arriving at Venice in the 18th century, a plague was discovered on two ships. The island was sealed off and used to host people with infectious diseases, leading to legends of terminally ill Venetians waiting to die before their ghosts returned to haunt the island.

In 1922, the island became home to a mental hospital where a doctor allegedly experimented on patients with crude lobotomies. He later threw himself from the hospital tower after claiming he had been driven mad by ghosts. The island has been featured on the paranormal shows Ghost Adventures and Scariest Places on Earth.

1.Ilha da Queimada– Brazil.

Details: – Ilha da Queimada Grande, also known as Snake Island, one of many Snake Islands around the world, is an island off the coast of Brazil in the Atlantic Ocean. It is administered as part of the municipality of Itanhaém in the State of São Paulo. The island is small in size and has many different types of terrain, ranging from bare rock to rainforest. The island has a temperate climate. The island is the only home of the critically endangered, venomous Bothrops insularism, which has a diet of birds.

The snakes became trapped on the island when rising sea levels covered up the land that connected it to the mainland. This left the snakes to adapt to their environment, increase rapidly in population and render the island dangerous to public visitation. Queimada Grande is closed to the public in order to protect this snake population; access is only available to the Brazilian Navy and selected researchers vetted by the Chico Mendes Institute for Biodiversity Conservation, the Brazilian federal conservation unit.
