The literal translation for Cueva Ventana is “Window Cave,” and once you get past the inescapable reality that one must trek through rocky, steep, dark, and bat-swarming terrain lasting roughly five minutes, there’s no question you’ll realize how worthwhile the journey is. The passage finishes off dramatically with one of the most breathtaking landscape views that Puerto Rico has to offer.
I had done my research prior to going, which meant that we were equipped with lanterns and flashlights. We were lucky to come across a few explorers who'd explored the cave already that morning and didn’t mind doing it again to guide us through much more quickly.
A few more caves are in the surrounding area—such as Rio Camuy Cave Park, which we didn’t get the chance to explore—but Cueva Ventana is a must-see. It’s best to arrive early, as the place has become more popular.
The entrance fee per person was $5. It would have been amazing to visit during the evening as the sun was setting, but I can’t imagine the extra depth of darkness all around.
