Most dangerous islands in the world

These islands look really dangerous.

Izu Islands, Japan

The seven Izu Islands are a group of volcanic islands in the Fuji Volcanic Belt that stretches from north to south for 280 miles. A reek of sulfur cannot be avoided or ignored because of the area’s volcanic nature. People who live there were actually evacuated in 2000 (and once in 1953) because the levels of gas were through the roof. They were allowed back in five years later. Residents of Miyakejima, one of Japan’s Izu Islands, must wear masks at all times.

Saba, Netherlands

The Caribbean island in the Lesser Antilles chain is a special municipality of the Netherlands. If you ever want to visit, make sure it’s during the winter. It has been hit by more major storms since 1851 than any other place on Earth. A total of 64 severe hurricanes have passed through the island until 2010, according to the Caribbean Hurricane Network. This is one every 2.5 years.

Gruinard Island, Scotland

This tiny, oval-shaped Scottish island is just about 1.2 miles long by half a mile wide, but it’s one of the most dangerous places on the planet. No one has settled on this British “Anthrax Island.” It used to be the testing ground for biological warfare during World War Two. It was so contaminated that it was deemed out-of-bounds for half a century. Anthrax spores remain in the soil.

Ramree Island, Burma

Ramree Island is home to thousands of saltwater crocodiles, which are the largest reptilian predator in the world. They can weigh about 2,000 pounds. Even a small one can kill a big person. These crocodiles are not only deadly, they are aggressive and known to attack people who enter their natural habitat. In fact, the “Most Number of Fatalities in a Crocodile Attack” took place at Ramree Island, according to the Guinness Book of World Records. If that is not enough, poisonous scorpions are everywhere as well as mosquitos carrying malaria.

Ilha da Queimada, Brazil

Ilha da Queimada is an island ruled by animals. Popularly known as Snake Island, it is home to thousands of the some of the most venomous snakes in the world, Golden Lancehead Vipers. The Brazilian Navy has banned all civilians from the island, which is just 20 miles off the coast of São Paulo. There are between one and five snakes per square meter (3 feet).

North Sentinel Island, Andaman Islands

This densely forested island is home to a group of indigenous people called the Sentinelese. Rejecting any contact to the outside world, the natives are believed to be among the last people to remain untouched by modern civilization. And they do not take kindly to strangers. They are prepared to attack anyone approaching the island, and have done many times.

Farallon Islands

The group of islands and sea stacks just about 25 miles west of San Francisco are off limits to people. The Southeast Farallon Island has a field research station where a few conservation scientists work. More than 47,800 drums and other containers of low-level radioactive waste were dumped onto the ocean floor west of San Francisco between 1946 and 1970, according to U.S. Geological Survey. The exact location of the containers and the potential hazard to the environment are unknown.


Few people visit Comoros because the islands are said to be infected with malaria carrying mosquitos. Hotels even have bed nets. A lot of people there wear masks. All water should be regarded as being potentially contaminated, according to the World Travel Guide. Water used for drinking, brushing teeth or making ice should have first been boiled or otherwise sterilized. Milk is unpasteurized and should be boiled. Hepatitis E is widespread; Hepatitis B is hyper-endemic.

Bikini Atoll, Marshall Islands

Though a UNESCO World Heritage Site, and often visited, Bikini Atoll is a highly dangerous place. It was the site of serious nuclear weapon testing between 1946 and 1958. Upon the declaration of reduced radiation levels, many returned in 1987. But it wasn’t safe. Crabs, foods and plants had been contaminated and soil was affecting abnormalities in childbirth. Original inhabitants have refused to return, and eating the locally grown produce is strongly discouraged.

Enewetak Atoll, Marshall Islands

West from Bikini Atoll lies Enewetak, where a concrete dome was placed to deposit radioactive soil and debris. After coming under U.S. control following the Second World War, residents were evacuated. Forty-three nuclear tests were fired between 1948 and 1958. Most of the atoll is not fit for human habitation due to high contamination and radioactivity. It is projected to be safe for tenancy by 2027.


Visiting this island continent poses a lot of risks. It has more venomous snakes than any other nation. Sharks and deadly spiders are not helping this surfing paradise’s reputation either. A lot of saltwater crocodiles live there as well. They have the most powerful bite of any species. Another danger is the southern blue-lined octopus because of its highly toxic venom. A single bite leads to paralysis in a few minutes, followed by heart failure.
