Cueva del Viento

Cueva del Viento (Wind Cavern), one of the Most Impressive Caves in Puerto Rico, located in the Guajataca State Forest near the northwestern town of Isabela, is easily accessible by trails that begin at the parking area and ranger station at KM 9 on Route 446.

Cueva del Viento is a volcanic cavity found in the same-named district of Icod de los Vinos. It was produced 27,000 years ago in basaltic lavas from the Pico Viejo volcano's initial eruptive phase, close to Mount Teide (Tenerife, Canary Islands). This lava tube, dubbed "Cave of the Wind" because of the strong winds that pass through it, is the world's fifth longest (18 kilometers documented to date), trailing only the four that can be found on the largest island of the Hawaiian archipelago (United States). It's a massive underground labyrinth with numerous unexplored branching that will likely grow to its overall length in the future.

Steps lead down from the cave entrance, but there is no lighting or guardrails inside, so wear sturdy shoes and bring flashlights if you wish to explore the cave. Beautiful stalactite and stalagmite formations adorn the cave's limestone walls. Be aware that the cave is also home to a large number of bats.
