The Arecibo observatory has a 1,000-foot (305-meter) radio telescope that was the world's largest single-aperture telescope for a half of century (now China build a bigger one). In 1974, the Arecibo Message, an attempt to communicate with potential extraterrestrial life, was transmitted from the radio...More

Since my husband is a space and astronomy fan I thought planning our morning in Arecibo would be fun. And it was! Using our GPS to travel from San Juan it took us an hour and 15 minutes to get there. They have English speaking...More

Awe inspiring. Nearly sixty years ago, a team of astronomers did what was thought to be impossible. They built a 1,000 foot diameter, radio telescope. The largest observatory in the world is still making new discoveries.

A serious MUST if traveling to Puerto Rico ! Absolutely fascinating and worth the drive from San Juan or Ponce. The tour is mostly self guided but the 15 minute film is excellent and quite informative.

The observatory is stunning and the landscape is gorgeous, but the tour is pretty ho-hum. The museum is geared towards kids and the guides were not especially informative. But I would nonetheless recommend this tour because the viewing platform over the dish is pretty amazing....More

A really difficult place to find, but a neat place to see. Located in a depression this telescope defies description. James Bond's "Goldeneye" was partially filmed here. Tour guide told us that Bond had to have a double on the cat-walk, as he was CHICKEN!...More
