If you are staying in Puerto Rico, definitely spend a morning or afternoon exploring this observatory. The science is fascinating, its size is amazing and the Visitor's Center has plenty of exhibits to help you understand not only how the observatory works, but also information on astronomy, physics and more. It is about a two hour drive from the San... More

It was interesting seeing this observatory and there is a small museum to visit before you actually see it. Staff was very nice and knowledgeable and answered any questions we had.

The admission is reasonable and the tour is informative. We paid extra for the VIP tour which goes behind the scenes including being eye level with the reflector. The museum is small but has several interactive exhibits for kids and maybe some of us curious adults. All in all a great experience.

The observatory was worth the drive if your interested in this type of attraction. It's a walk from where you park up to the entrance, but the museum, film, and the observation area present a lot of interesting information on the construction and usage of the telescope.

We LOVED coming here. What a wealth of information! That being said take your time and read the exhibits. Very cool information. There is food available for sale here but it's mostly hotdogs and soda (stuff like that) if that's not your thing there are towns you travel through to get there with cute restaurants. The locals are very nice... More

Since I was a kid, I have been fascinated by extraterrestrials and UFO's. the possibility that life outside our planet is intriguing and exciting. After watching the X-Files episode where the observatory was at the center of it, my fascination grew by a million times. A school trip gave me the opportunity to travel there and drool over it.

No trip to San Juan is complete without a visit to the Arecibo Observatory--even if you are not into science, how can you pass up the opportunity to stand before the LARGEST telescope in the WORLD??? If that is not enough to "peak" your interest, how about the fact that this was the setting for the movie CONTACT with Jodie... More

We visited the Arecibo Observatory after visiting the Rio Camuy Caves about 30 minutes away. The trip started with a drive to the radio telescope through beautiful karst topography. Once you get there there's a semi-steep climb (with a few stairs) up to the top of a hill. You start by purchasing tickets and entering into a wonderfully air conditioned... More

If you're staying in San Juan it's a bit of a trip to get there, nearly 1 1/2 hours, but if you have any sense of wonder and curiosity about science and astronomy it's absolutely fascinating. We were there only about an hour, so it might seem a little ridiculous to drive three hours and spend an hour, but it's... More
