Also known as the "Gates of Hell," this flaming pit was formed in the 1970s when geologists drilled into a cave for oil, causing its natural gas field to collapse. To burn off the toxic gas, they set it on fire. Decades later, it's still burning in the remote Karakum Desert.

A popular location for adventure hikers, Villarrica is one of South America’s most active volcanoes. It last erupted in 2015, spewing ash and lava up to 3,300 feet (1,000 m) in the air.

Filled with red gorges and emerald pools, this wild and beautiful national park is an Australian pearl. However, located in the remote part of Western Australia, it's prone to extreme weather conditions and rockfalls, which have led to fatalities.

Built between 1901 and 1905 for construction workers carrying goods, the risky path attracts adrenaline junkies from around the world. With several hikers having fallen to their deaths there over the years, the path today has new visitor restrictions, making it much safer than it once was.

Mount Everest, Nepal

Climbing the world's tallest mountain is on the bucket list of many. At over 29,000 feet (8,850 m), Mount Everest attracts around 1,200 climbers each year. However, only about half ever reach the summit, and several others die trying. The main causes of death on Everest include subfreezing temperatures and changing altitudes. In 2019, 11 people died on the peak.

During the drier months of the year, the Zambezi River gets low enough to reveal the ultimate infinity pool at the edge of the world's highest waterfall, Victoria Falls. Swimmers take the plunge at their own risk, as they could be swept down the waterfall.

One of Ireland's most impressive sights, the Cliffs of Moher feature a dramatic scenery that unfolds for five miles (eight km), reaching more than 700 feet (over 210 m) at its highest point. However, it comes with great danger. More than 30 accidental deaths have occurred here since the early 1990s.

Mont Blanc, France and Italy

The highest mountain in Europe, Mont Blanc reaches around 15,780 feet (over 4,800 m). With 30,000 visitors per year, it's considered one of the deadliest mountains in Europe. This is mainly due to fatal climbing accidents resulting from lack of preparation, as well as treacherous terrain and changing weather conditions.

Colorado River, USA

Passing through five states, the 1,450-mile-long (over 2,330 km) Colorado River is a popular swimming spot for vacationers. However, what people don't realize is how dangerous the waters can be, particularly after heavy rains and an increase in melted snow. In fact, 2014 had a record of 15 deaths in the first seven months due to these conditions.

This impressive rock formation has become a popular spot for selfie-taking hikers. At around 3,600 feet (nearly 1,100 m) above sea level, there have sadly been reports of hikers falling to their deaths.

One of the world's most dangerous roads, North Yungas Road has become a thrilling ride for mountain bikers. A bumpy and narrow 40 mile (about 65-km) road, one wrong move and it can prove fatal.

Under the jungle of Mexico’s Yucatán Peninsula lie three of the longest underwater cave systems in the world. These unmapped cave systems have become a magnate for divers who want to explore the ways between the natural sinkholes, known as cenotes. However, the tight spaces, darkness, and disorientation can lead to fatal events.

Mainly situated in Wyoming, the park spreads into parts of Montana and Idaho, too. On top of a volcanic hot spot, the real dangers for hikers and campers are the grizzly bears. However, on average we're talking just one bear attack per year.

Annapurna I, Nepal

The 10th-highest mountain on the planet, the Annapurna I is notoriously difficult to climb. Ranked as the world's most deadly peak for climbers, it has a high fatality rate due to its treacherous topography, inhospitable conditions, and high altitude.

At 300 feet (90 m) high and 560 feet (170 m) long, the Trift Bridge in the Swiss Alps should be avoided by people with acrophobia (i.e fear of heights). One of the longest and highest pedestrian suspension bridges in the Alps, it takes three cable car rides to reach it.
