While mass tourism transforms the nearby islands, El Hierro—the most westerly and wildest of the Canary Islands—has quietly embraced a different path. This remote island has carved a reputation for its commitment to sustainable tourism, its rugged landscapes, and its distinct charm.
A Geological and Ecological Wonder
El Hierro, a heart-shaped formation off the west coast of Africa, is the youngest and second smallest of the Canary Islands. It emerged from the Atlantic Ocean around 1.2 million years ago, the result of undersea volcanic eruptions. This violent geological history has created a strikingly varied landscape, from fertile valleys and evergreen forests to sky-high cliffs and lunar-like volcanic cones.

Clive Muir – Wildside Holidays – Walking, wildlife and culture holidays in Spain
I’ve been living in western Andalucía for more than 20 years and spend much of my time researching and running English-language travel websites about Spain. My work covers destinations including Cádiz, Ronda, Grazalema and the Caminito del Rey, as well as Wildside Holidays, which focuses on walking, wildlife and nature travel in Spain.
Through Wildside Holidays, I share practical information about Spain’s natural parks, mountains, wildlife and walking destinations, drawing on many years of living and travelling in the country. The aim is to help visitors discover Spain’s natural landscapes responsibly and plan rewarding walking and wildlife experiences.
