Climbers on the black slopes of the Cerro Negro volcano, one of Central America's fesitiest volcanoes. According to the Smithsonian, Cerro Negro has erupted at least 20 times since 1850, as recently as 1995. At 400 meters, it's an easy hike to the top, and an even easier trip down: the steepest slope is coated in ash, perfect for sliding!
