This cave is open to anyone, just leave your car at the gas station (road #10 - Arecibo), get your gear ready and enjoy the adventure. "Cueva ventana" (Window Cave) is a miracle of nature, easy to access and your kids will love it (no babies please). It is important to have a flash light, if you do not have... More

I took a group of university students from the Intercultural Association at IUPR. The caves are right off the road and a very short walk. They are well worth the view. Very glad that we chose the caves as one of the stops. I liked these caves a lot better than Camuey and these were free. More

It's free.. When you get to the gas station beside the entrance, the only thing to do is park the car.! Its obligatory to have a flashlight.! Then walk like 10 minutes and enter to the cave, is like 5 minutes throughout the cave and finally the great view.. Enjoy More

This is a wild cave, not a guided tour. It's free. You'll need proper footwear, and a flashlight, headlamp, or some other portable light source.

I wend with my family. It is easy to find but make sure to bring a flash light. The view is breathtaking. More

My wife, mother and father took the trip to this awesome cave. Before you leave, make sure each person has a flashlight and water (and beer for afterwards). I took a headlamp, which you can buy at Walmart for $12 that allows you to free both hands. Make sure you are wearing either tennis shoes that you don't mind getting... More

It was raining when me and my friend went there. The trail was muddy and we went on a wrong way at first. But we manage to get there and the cave itself was dry and clean. The view was definitely AMAZING. Overall the hiking was not too long, just a bit slippery. As suggested by Daytrip Puerto Rico we... More
