5 terrifying extreme sports destinations around the globe

Mount Huashan is about 6,800 ft (2072 m) high. It's located in China’s Shaanxi province. The mountain boasts of impossible sheer drops and crags in the cedar-studded limestone.

Climbing the mountain is almost impossible, but everyone can reach its highest points using the terrifying “trail system” constructed in the early 1800s.

Scuba divers, spelunkers and just people they can help are attracted by this mysterious place: what can be better than swimming through pitch-black caves and tunnels hundreds of meters below the surface?

The passageways have been mapped to lengths of 400 meters (1,300 ft) and what makes it scary is that there are unexplored depths still.

These are ancient sandstone formations in Ireland, formed from the same rocks as the famous Giant’s Causeway.

Somehow, mountain cyclists have learned to balance their bikes on the ledge, which shrinks to 10 centimeters or 4 inches (OMG?) in some places.

Everyone heard about climbing mountains and icy peaks, right? Well, climbers came up with something more dangerous and bizarre. In Canada’s Rocky Mountains, extreme climbers target frozen waterfalls up to 182 meters (600 ft) high!

Mount Pacaya in Guatemala rises to over 8,000 ft (2400 m) and has erupted 23 times since Spanish colonization.

Despite this fact, extreme climber are still attracted by the cinder cone. They all are ready to suffer heat, smoke, and even have the probability of having melted running shoes if they miss a step. To them it's part of the thrill.
