Volcano boarding sends thrill seekers careening down the side of this active Nicaraguan volcano, reaching speeds of up to 90 kilometers per hour. Riders mount a wooden toboggan constructed of metal and Formica-reinforced plywood.
Lava boarders must hike nearly 2,400 feet to the rim of the Cerro Negro volcano, which is monitored by the Nicaraguan Seismic Network, an organization that measures the volcano’s seismic activity, gas concentrations, and temperature fluctuations. The Cerro Negro has erupted about 23 times, changing the altitude of the slopes depending on the eruptions.
