Most Dangerous Places to Visit and Why They're So Risky

Bikini Atoll looks like a tropical paradise, but it's a radioactive ghost town.

Once the site of US Nuclear tests, the island is still contaminated despite its crystal clear waters and

untouched beaches.

Radiation levels remain dangerously high.

Tourists are allowed, but staying overnight is discouraged.

Beauty hides a deadly past.

Here, literally glowing with danger.

Lake Natron in Tanzania is stunningly red, but it's also deadly.

The lake's high alkalinity can burn skin and eyes, and its temperature can reach 140 degrees Fahrenheit.

Birds that land on it often calcify, preserved like statues.

It's a surreal alien landscape that looks like Mars, but it's Earth's own natural death trap.

Ilha de Queimada Grande, or Snake island, is off limits for a reason.

Located off Brazil's coast, it's home to thousands of golden lancehead vipers, one of the world's deadliest snakes.

There's roughly one snake per square meter.

Even the Brazilian Navy avoids it.

It's paradise for snakes, but a nightmare for humans.

Chernobyl is now a dark tourism hotspot.

But the danger isn't gone.

Radiation lingers in the soil, buildings and even wildlife.

Some areas are safe for short visits, but others remain lethal.

The eerie silence, abandoned towns and mutated flora make it feel post apocalyptic, its history frozen in time

with invisible threats still lurking.
