Arenal Volcano near La Fortuna Costa Rica. Dormant pyramid volcano until 1968 when it blew much like Mt St. Helen's in North America. Since then many tourist and vulcanologist have made this a must see tourist attraction. That, and the naturally heated river that runs from the base of the volcano and is diverted into resort hotels like the Arenal Springs Resort. Costa Rica is the closest thing to a real "Pandora" on Earth...Amazing!
