Arenal Volcano, measuring approximately 5,437 feet with a crater spanning 460 feet, is considered one of the ten most active volcanoes in the world, with eruptions occurring approximately 40 to 45 times per day. The perfect conical shape of the volcano offers astounding views of volcanic activity at the summit and vibrant lava flows from the crater.
