Arenal Volcano or Volcán Arenal, in Spanish, is currently the youngest and most active volcano in Costa Rica. During our trip we got to see this spectacular natural attraction while visiting Arenal Paraíso. Arenal dates back about 4000 years and, before the catastrophic eruption of 1968, was considered extinct since it had been silent for a little less than half a century. On the morning of July 29, 1968 it suddenly violently erupted, blowing a huge hole out the side of the volcano. The eruption killed 87 people, covered three villages and formed three new active craters in the volcano. Since then it has had continuous activity with major eruptions occurring in 1973, 1975, 1993, 200, 2003, and 2005. Fatalities caused by the volcano have been limited to tourists and guides that wandered too close. Minor eruptions occur every 5-10 minutes. While our group was down there we were lucky enough to clearly see lava flow at night, especially since it is a cloudy region and doesn't always have great visibility . The information used above is from http://www.arenal.net/ for more information about the volcano’s history or to view spectacular photos go to the link above. Although the photos are incredible actually seeing the volcano's grandeur in person is indescribable, so for tourist information about visiting Arenal you can go to the above website or go to http://www.arenalvolcanotours.com/.
