Have you ever imagined what it’s like to walk through a cave formed by molten lava? On the island of Tenerife in the Canary Islands, a world of underground wonder awaits: the Cueva del Viento, one of the longest lava tubes in the world.

Returning to Tenerife’s Volcanic Majesty

My first visit to Tenerife was a journey to explore Mount Teide, the imposing volcano that defines the island’s landscape. Driving from sea level to nearly 13,000 feet and back in one day was an unforgettable experience. As I left, I knew I’d return—Tenerife’s geological marvels beckoned me back. And so, here I am again, this time diving below ground to explore Tenerife’s ancient lava tubes, a hidden world shaped by fiery forces.

Cueva del Viento: Tenerife’s Subterranean World

In Spanish, “cave” is called Cueva, and Cueva del Viento (Wind Cave) is aptly named for the natural air currents circulating through its openings. Located in Icod de los Vinos, this lava tube extends roughly 17 kilometers beneath the surface, though only a portion is open to exploration. Formed around 27,000 years ago by lava flows from the Pico Viejo volcano, this cave is not just an underground passageway; it’s a window into Tenerife’s volcanic past.

What Makes Lava Tubes Unique?

Lava tubes form when the outer layer of a lava flow cools and solidifies, while molten lava continues to flow beneath. Once the eruption ends, the inner lava drains away, leaving hollow tunnels. Over time, other forces like erosion and tectonic shifts further shape these spaces, creating the labyrinthine networks found in Tenerife.

The lava tubes on Tenerife provide a glimpse into the power of volcanic activity—and are even reminiscent of the settings in Jules Verne’s Journey to the Center of the Earth. Although fictional, the novel describes lava tube formation with surprising accuracy.

Planning My Visit to Cueva del Viento

To visit Cueva del Viento, I booked a guided tour through the Cueva del Viento Interpretation Center. After a 15-minute drive from the center, we hiked for another 20 minutes through a lush forest, navigating a path known for its hidden “skylights” or collapsed sections of the cave’s roof. These openings are marked with protective barriers, as accidents have occurred.

Upon reaching the entrance, a “skylight” that lets sunlight and air into the cave, we descended into the lava tube. Our guide explained how air currents funnel through these skylights, helping keep the cave oxygenated, a feature that not all caves have.

A Walk Through Time Inside the Lava Tube

Once inside, we were enveloped by a rugged landscape. The floor was uneven, full of jagged rocks where lava had cooled unevenly over millennia. As I looked around, I could see why this harsh terrain has limited life—only certain hardy species like bats, spiders, and other small cave-dwelling creatures manage to survive in this stable but challenging microclimate.

The lava tube contains three distinct levels, with tourists allowed only on one. As we walked along, some sections of the tube felt eerily geometric, like a mine carved out by humans. Our guide explained that the third, deepest level has a higher ceiling and a grandeur not visible from the accessible areas.

Experiencing Total Darkness

At one point, our guide instructed us to switch off our headlamps. The resulting darkness was absolute, a void that seemed to erase the boundaries of the cave. This sensory deprivation heightened my other senses, allowing me to feel the raw, untouched atmosphere of Cueva del Viento. In that moment, I could understand why ancient civilizations considered caves sacred—a place removed from the familiar, silent and still.

Practical Information for Visitors

Cueva del Viento’s entry and exit points are limited, and exploring the cave safely requires a guide. The 2-hour tour involves some rugged hiking and headlamps are provided, but visitors should wear sturdy shoes and comfortable clothing. The Interpretation Center’s guides ensure a safe and informative experience, while protecting this unique natural wonder.

The Canary Islands: A Land of Endless Exploration

From the peak of Mount Teide to the depths of Cueva del Viento, Tenerife offers a spectrum of experiences that can only be found in volcanic landscapes. The lava tubes are just one example of the wonders carved out by nature over time, reminding us of the Earth’s immense power and hidden beauty.

Tenerife may be known for its beaches and warm weather, but its volcanic formations hold a beauty of their own. Whether you’re a geology enthusiast or simply an adventurer at heart, the lava tubes of Cueva del Viento are an experience you won’t want to miss.
