Arenal Volcano is an active andesitic stratovolcano in north-western Costa Rica around 90 km northwest of San José, in the district of La Fortuna. The Arenal volcano measures at least 1,633 meters high. It is conically shaped with a crater 140 meters in diameter. The Arenal Volcano became famous because it consistently spewed lava, gas, and ash until it went into a resting phase, in 2010. Although you can no longer see lava, the perfectly symmetrical volcano it is still impressive. Clouds obscured our view but it still seems magical.
