Cueva Ventana
A cave near Arecibo whose mouth opens like a window over the Río Grande de Arecibo valley. The visit is guided, with helmet and headlamp, and the walk is short but uneven underfoot. It is one of the most photographed stops in the north and worth booking ahead in high season.
Exemple
The classic photo is taken from inside the cave looking out, with the mouth framing the valley.
