This tour takes you to the northwestern part of the island. Camuy Caves Park is known as one of the most massive cave networks in this hemisphere. Recently two craterlike sinkholes and caves within this network have been beautifully developed. The caverns are easily visited with modern trolley cars taking you down the entrance of the caves. You will then enjoy a guided tour of the great cavern system seeing the Underground River as well as huge stalagmites and rocky ravines.
After the caves we will be on our way to the Arecibo Observatory, which features the world’s largest radar/radio telescope and is operated by Cornell University. The Observatory is conducting groundbreaking astronomy work, including the SETI (Search for Extraterrestrial Intelligence) program. A 20-acre radar dish, with a 600-ton suspended platform hovering over it, sits in an impressive 565-foot deep sinkhole while it examines planets and monitors natural radio emissions from distant galaxies, pulsars and quasars….all from Arecibo!
