If sliding down an active volcano at 30 mph doesn't make you feel like a bad ass, I don't know what will. Volcano boarding is the twist on snowboarding that turns up the heat...a lot.
The board is specially designed to help you glide down the rock hard volcanic "slopes". Made out of metal lined plywood, these rock sleds are slightly terrifying. But to be fair, it's the danger and rush of flying down a volcano that makes this sport so sweet.
