Charco Azul (La Frontera, El Hierro)
El Hierro is a place everybody should look at when discussing renewable energy, due to the green politics established on the island. Thanks to Eolic and hydraulic energy, the two cities on the island survive due to renewable resources. El Hierro boasts an abundance of natural pools in which to lay back for hours. Charco Azul, located in La Frontera, offers the rich benefits of seawater. Stay at the modest and comfortable Jucar Aparments near the natural pool, and get most out of your free spa session between the volcanic rocks.
