So first things first: Arenal is not the name of a town in Costa Rica. Folks will refer to the area around Arenal Volcano as Arenal, but the closest town to the volcano is actually La Fortuna. Still, between Lake Arenal, the volcano, and the many places in the region referring to themselves as Arenal, it gets confusing.This stunning part of Costa Rica is where you will find natural hot springs, lots of outdoor adventures, waterfalls, resorts, and immense natural beauty. Anyone who has visited Arenal Volcano National Park or La Fortuna, Costa Rica, can attest to how incredible the area truly is.
