The extreme sport, known as volcano boarding, sees thousands of thrill seekers race down the Cerro Negro volcano in Nicaragua, Central America each year.
Wearing little more than a jumpsuit and goggles for protection, daredevils can careen down the 726m high ashy slope in less than 20 seconds at speeds of up to 60mph.
Cerro Negro (Black Hill) is an active volcano outside of Leon, Nicaragua. It’s a relatively new one at only 161 years old. Because the cone is primarily made up of small penny-sized grains of volcanic rock, it’s possible to ride or surf down the steep slope on a wooden sled.
The volcano boards have a rope in front for your hands as you lean back for maximum speed. You can’t really control your direction with the rope though, it’s only for stability. The bottom of the wooden sled is covered with a thin layer of metal.
While the volcanic stones are very lightweight and easy to break apart, they are also very sharp. They can tear holes in clothing or skin pretty easily without the protective gear.
