To say that the Observatory radio telescope is big is an understatement. The satellite occupies the valley of three hills. The facility is located in the middle of country side, about two hours from San Juan. There are tours from San Juan that make the trip to the Observatory and the Camuy Caves, so check it out and tale advantage.... More

My husband, who is ham radio operator, wanted to see arecibo, so we went before our cruise. I booked the tour with Robert Moreno from Borikua Tours. He was wonderful and would highly recommend him. He promptly picked us up at our hotel at 9:00 AM and our final drop off was the cruise terminal at about 3:00PM. He is... More

It's pretty amazing to see this place in real life, fitting in nicely with the mountains around it. My kids were amazed! Inside, a nice little museum with interactive exhibits that kept the kids entertained for a bit while it rained outside.

My family, with two adult children, had a terrific time here. The new visitor center does a great job of explaining the role of the observatory and offers a birds eye view of the whole thing. Of the four of us, only two were interested in science but we all enjoyed the experience. The only fly in the ointment is... More

Unlike some of the reviews, we had no trouble finding this site, located up in the hills/mountains on some back roads. It was worth the trip just to see this unique piece of technology. Not much of a visitor center, and even worse with 100 local 6 year olds hopped up on sugar or something - couldn't even hear inside.... More

With its 300 meter diameter the Arecibo radio telescope is the largest in the world. The tour includes a 30 minutes movie that explains it all. Also there are a lot of interactive experiments which are very educational about outer space and physics. Eventually your guide brings you outside where you can look at it!

The Arecibo Observatory is a technology born from a grand vision! The idea to build this 900 ton radio satellite started in the 1950s and it has generated endless possibilities for scientist to extract new information about our solar system and atmosphere that can produce more solutions for human society. The views at the observatory's balcony is extraordinary. That part... More

Hello: We are glad you enjoyed your visit and also, thanks for leaving your comments. We just wanted to clarify that entrance to the observatory's balcony is not free. That is part of entrance fee which, like you said includes self-guided tour in our two-story Visitor Center, a short movie and a talk by one of our guides at the... More

We enjoyed our drive through the small towns, with excellent signage, to the observatory. The movie explains a great deal and then the guide takes you out to see the large dish. It is amazing what scientists can do. The museum has a large number of well-done and easy to understand exhibits. I'm not truly disabled, but recently had knee... More

The journey here to this place is pretty scenic, lots of turn around farmland. Its very deep inside the farms and residential area but gps will bring you there. There is an exhibition with different scientific stuff, should be good for kids for okay for us. Watched the video and the guide brought us out and gave a pretty good... More

There is a hike to the facility. There are taxis who will drive you to the top if you need it. The science museum was low tech but very informative. I even learned a few things. They have some really cool displays. There is a slice of rock from Mars, different kinds of meteorites, what elements come from, and wave... More
