Volcano boarding outside of Leon Nicaragua is a must for anyone that like adrenelene junky sports. It takes about 1hour to get to the active volcano through some great country. Then the journey begins by strapping your board to your back and climbing up the volcano for about an hour. Take the scenic tour of the smouldering craters and awesome views of the countryside before you hit the ashfields and descend on your board. Boarding takes about 45 seconds and goes all the way to the bottom. This is not for the faint of heart and the hike up is enduring but well worth it.
I recommend Arny at Mas Adventures in Leon masadventures@gmail.com. He was one of the first to board the volcano in 2004 and his son Deigo at the age of two was the youngest to do it. Mas Adventure will take you in a 4x4 with a small group for $28 (including park fees). If you choose like most to do Bigfoot, expect a huge group, no tour of the volcano and a very young crowd.
This is a one-in-a-lifetime thrill that I can highly recommend.
