Barranco del Infierno, Special Nature Reserve in Adeje, Tenerife, Spain.
Barranco del Infierno is a protected ravine in Tenerife featuring deep canyons, narrow ridge lines, and distinctive rock formations scattered throughout the landscape. The terrain shows complex geological patterns with several named rock clusters that rise prominently from the valley floor.
The reserve was formally protected in 1987, establishing its status as a conservation site of regional importance. The hundreds of natural caves within its walls served as shelter for ancient inhabitants, becoming places where they left behind evidence of their settlement.
The reserve shows signs of how the Guanche people once made this place their home, with their daily marks still present in the landscape. Walking through the canyons, visitors can spot rock carvings inside caves that reveal details about their life here.
Visiting requires advance booking because the reserve accepts only 200 visitors each day to protect the environment. You must wear a safety helmet and closed shoes while hiking, as the trails involve exposed sections with steep drops.
The reserve holds one of Tenerife's rare year-round water flows, featuring a waterfall that stands out in this otherwise dry landscape. This water source allows uncommon plants to grow, including a species of willow found only in moist pockets of the island.
