Cueva Ventana
A natural “window” cave in a karst cliff. Looking out from inside, you see the emerald Arecibo valley framed, making it one of the island’s most famous photo spots.
Cueva Ventana sits on a limestone cliff between Arecibo and Utuado. One end of the cave opens onto a cliff face about 50 meters high. Looking out from the dark interior, the opening resembles a window framing the valley and hills, and backlit silhouette photos are very popular. The cave lies within a private reserve, and entry requires a guided tour of about 1–1.5 hours, including a helmet and headlamp, costing about US$20–30. Your guide will explain Taíno rock art, the bats inside, and the karst landscape. The path to the cave entrance has gravel and steep slopes, so wear non-slip shoes. The entrance is near a gas station beside Highway PR-10. It is about 1–1.25 hours’ drive from San Juan and can be combined with Río Camuy Cave Park (if open) or the Arecibo coast for a day trip.
