Tour Description

The Rio Camuy Cave / Arecibo Observatory Tour first starts at the site of the largest underground river in the world, “Río Camuy," in the Karst region that runs from Loiza to Aguadilla along the north coast of Puerto Rico.  A trolley car takes guests to the entrance which starts the guided tour that will take you through a section of the Camuy Cave System.

After the Rio Camuy tour, we will continue close by to Arecibo, where the world’s largest single dish radio telescope sits in a natural bowl among the Karst formations unique to the area. The telescope was the setting of the movie "Contact," starring Jodie Foster.

    Went on this tour last week with my family. The caves surprisingly large. It was dark but as long as you have a camera with a strong flash you are good. We stopped at a local restaurant for lunch. Delicious food and great prices! The observatory was closed for renovations, but guide explained that they had adjusted the tour to include a place called "cueva del indio". This was incredible. We hiked up a rocky hill and climbed down into the cavern. All this was along cliffs lining the Atlantic Ocean. Breath taking views! I would have stayed there all day!
