The Iconic Arenal Volcano

At the heart of the park stands the Arenal Volcano, one of Costa Rica's most famous landmarks. Towering at 1,633 meters above sea level, this once-active volcano is now in a resting phase, but its dramatic cone shape dominates the skyline. Surrounding the volcano are lava fields and volcanic rock formations, remnants of past eruptions that give the landscape a rugged beauty. Learn more about the park’s volcanic history in our guide: The Story of Arenal Volcano: From Activity to Dormancy.
