Cueva Ventana is located in Arecibo, and makes a perfect day trip from San Juan along with the Cueva del Indio and Arecibo Observatory.
Take Route 22 (East or West depending on your point of origin) to Route 10 South and take exit 75B to KM75. You can park in their designated parking lot but aim to get there earlier rather than later to avoid large groups.
The hike of the cave takes about 45 minutes to an hour, depending on your pace, but it is recommend that you take two or three hours so you can view and enjoy all that the cave has to offer. There are parts of the hike that require climbing, so a moderate level of fitness is needed and those with special health issues like heart disease or joint issues may want to consult with the staff before attempting it. At the end of the hike is an epic view of puerto rico as you look out of the ventana, or window, upon a sublime valley below. This window has been the setting for many silhouette photos.
Getting to the caves is easy and can be done without a tour or group, best with a rental car. Just plug the destination into your GPS (Americans will be happy to know there is no need to use roaming or international data plans in Puerto Rico) and follow the directions.
In case you need it, the exact geo-coordinates are 18°29’34.1″N 66°38’31.4″W. It’s about an hour and a half from either San Juan or Aguadilla so you can access it from both coasts.
