After a short security film, we will take a trolley to the cave entrance. Our first stop is the Camuy Caves a 268-acre ecosystem that is part of this hemisphere’s most impressive subterranean cave network, intricately carved by the mighty Camuy River, located in the center of the island. Going through the dense tropical vegetation down the mouth of Clara Cave. 170 feet in height and million of years old were you would see stalactites, stalagmites and columns. Stop at the 650 ft. wide Tress Pueblos sinkhole, where special platforms allow visitors to view the river passing 400 feet below from one cave to another. Stop by the Spiral Sinkhole, where visitors can actually descend some 205 steps to reach its striking entrance.

The tour lasts approximately 2 hours including the descent into the cave in trolley. After we will take you to one of Puerto Rico’s most recognizable landmarks, the Arecibo Ionospheric Observatory. Built in 1963, it is a very important part of investigations of inter-spatial communications in the US, located in a natural sinkhole and one of the world’s most powerful active radars and the largest single unit radio telescope in the world, operated by the Eastern University of Puerto Rico. When it’s not being used as a set for movies, like James Bond’s Golden Eye and the Sci-fi thriller Contact, the Observatory is conducting groundbreaking astronomy investigations including the Search for Extraterrestrial Intelligence Program. You will be impressed by this galaxy-examining telescope composed of a 20-acre radar dish, the largest in the world, with a 600-ton platform suspended in a 565-foot deep sinkhole.Once we get to the observatory, we’ll walk up a fairly steep hill to get to the observatory itself. The walkway is a combination of steps and an inclined sidewalk, but the observatory offers a free ride to the entrance for elderly & handicapped guests.
