Cueva Ventana, Protected area in Arecibo, Puerto Rico.
Cueva Ventana is a limestone cave system in the region with multiple chambers containing natural formations like stalactites and stalagmites. A natural window in the final chamber opens to views of the Rio Grande valley below.
The cave came under protection in 2012 when environmental authorities acquired the surrounding land to prevent damage. The action became necessary to safeguard the geological features from ongoing harm.
The cave gained recognition through television productions that brought it into the spotlight for global audiences. Visitors come today partly to experience the connection between nature and popular media that shaped the site's reputation.
The cave can only be explored with a guide on 90-minute tours that provide safety equipment and flashlights. These guided experiences help visitors learn about the geology and local wildlife while staying safe.
The cave entrance displays ancient petroglyphs left by the region's original inhabitants. Visitors can also observe bat colonies living inside the cave during their tour.
