They're big, they're filled with molten rock, and, from time to time, they like to show off for the outside world.
But you've never let the threat of a little lava stand in the way of a good time.
Introducing Volcano Boarding, your chance to take a high-speed slide down the sandy slope of a Nicaraguan rumbler, running now.
Basically, this is your chance to find the same rush of speed you get in the Swiss Alps—only someone swapped those well-traversed snowy peaks for 1,600 feet of volcanic pebbles. A brave outfit called Tierra Tour will bus you to a peak known as Cerro Negro, hike with you to the top and outfit you with the necessary jumpsuit, pads and good wishes—and then you tear down the rough slope on a snowboard-style wooden plank. (You need something tougher than a regular board to stand up to this terrain.)
The last eruption was in 1999, disrupting boarding for a solid two days, and there could be another any day now. So you'll want to watch your back—or request a toboggan-style board that'll rocket you down at up to 40 miles an hour.
Which we're pretty sure is faster than lava.
