The Arenal region consists of the area directly beneath the volcano near the town of Fortuna and the Lake Arenal area. The Arenal Volcano is one of the most spectacular sites in Costa Rica and it is an absolute must see. One of the most consistently active
volcanos in the world, this awesomely powerful, colorful mountain erupts with tremendous force several times per day.
