Key Facts

Isla de Hierro, commonly known as El Hierro, is the smallest and westernmost of Spain's Canary Islands, forming part of the province of Santa Cruz de Tenerife. Located approximately 300 kilometers off the coast of northwestern Africa, this volcanic island spans just 268.71 square kilometers and has a population of around 11,000 residents. As the final island in the Canarian archipelago, El Hierro holds the distinction of being designated a UNESCO Global Geopark due to its unique geological formations, including volcanic cones, lava fields, and dramatic cliffs that plunge into the Atlantic Ocean. The island is administratively divided into three municipalities: Valverde (the capital), Frontera, and El Pinar. Remarkably, El Hierro has achieved near-total energy self-sufficiency through its Gorona del Viento wind-hydro power plant, making it a global model for renewable energy.
