You trek up the 728m hill to the cone, from where the three-minute-or-so long downhill slide starts, touching speeds of nearly 100 kmph. Nicaraguan tour operator Vapues Tours offers a volcano-boarding group excursion that includes transportation, training and gear (from $25 per person volcanoboard.com).
