Arenal Volcano is the most active volcano not only in Costa Rica but feature among the active volcanoes in the world that often spit fire. There has been no record of the eruption of Arenal Volcano in the historic times. It was in 1968 that it erupted with a vengeance and killed 78 people and reducing the small town of Tabacon into rubbles. Since then Arenal Volcano has remained active. Eruptions in Arenal Volcano are punctuated by minutes or hour long breaks. The blowup includes lumps or fountains of fluid basaltic lava that are ejected from the central crater. Arenal Volcano is one of the fascinating tourist attractions in Costa Rica .

The Arenal Volcano reaches a height of about 1,633 meters. It is conical in shape and the diameter of its crater is 140 meters. Though its existence can be traced back to nearly three thousand years, yet the geologists tout it as a young volcano possibly because of the fact that it still continues to show signs of growth. Though the volcano has lost its fierceness over time, you can still be witness to the fumes of ash, orange lava flows and explosions that are characterized by their suddenness. The explosive eruptions appear to be a spectacle of lights by night. The red hot boulders that are ejected out by the volcano will bedazzle you by their sheer radiance. You can view the perfect cone anywhere in the vicinity, but a good view of the eruption requires that you stay put in the lodges that also double the observatory.
