Expensive for what it is. They basically have a film you watch for 20 minutes and then the tour guide takes you outside and gives you a 10 minute talk. Inside they have a few exhibits for you to look at.

If you have an interest in interplanetary exploration, it will help you in finding the observatory. It is tucked away on some fairly remote single track roads in some rugged, but amazing scenery. There is a very steep climb up from the parking lot, definitely not for the faint hearted, before arriving at the visitors center. The center has some... More

This is a true sight to see, this to me is like the George Washington bridge; a marvel of science. The foresight to think years into the future. This is still the largest and most accurate and just awesome to see. The walk up to the observatory is a bit of a doozy however. It is steep at some points... More

We visited the dish because it is a must-see place in many guide books. The observatory was about an hour and a half from old san juan and we went there on the way back from the camuy cave. The dish is on a mountain and and there are a lot of winding roads to get there but it wasn't... More

Very cool to see the observatory and its hands on museum. The movie that was shown prior to venturing outside really gives you great concept knowledge of how instrumental this site really is. The staff is friendly and very knowledgeable. FYI: you park your car in the parking lot but must walk up the stairs uphill to the entrance. Not... More

I was traveling in Puerto Rico when I found out that the world's largest radio telescope and famous scene from Golden Eye was in Arecibo. It is far from the center of San Juan (about a 1hr 1/2 drive) but I thought it was well worth it. If you are out there you should also check out the Camuy caves... More

If you like space, James Bond (This was the location for the final scene of Goldeneye) or both then this is a must-visit place. Plenty to see, fascinating.

We saw this as part of our tour to the caves so it was a nice add on. However, if we had only gone to see this it wouldn't have been worth the 2 hour drive from our hotel. The museum is a bit worn down and out of date (pluto is listed as a planet). There was construction on... More
