Hoyo de La Sima and Lavas de San Juan Loop

This challenging trail features highly varied terrain. You'll navigate defined paths across rough lava surfaces, unpaved sections, alpine paths, natural trails, and some paved or gravel stretches.

Appropriate hiking footwear is crucial due to the potentially cutting nature of the volcanic rock.

You'll traverse the impressive Volcanic Trail Through the Pine Forests of La Palma, including the "Coladas de San Juan" lava flows from the 1949 eruption. A major highlight is the Hoyo de la Sima, a deep volcanic fissure. You'll also enjoy impressive views of the Caldera, El Paso, the Aridane Valley, and the View of Tajogaite Volcano.

Its mouth acts as a natural "eye," allowing light to filter in and create a play of shadows and colors on its moss-covered walls. While a secured path allows exploration around its rim and steps offer a short descent, venturing deeper requires specialized techniques.
