The facility is worth the drive and it is wonderful to behold this marvel of science. Great work and research that incorporates young people and the young at heart.

If you have a GPS you will find this under attractions in Arecibo and it will take you right to the security entrance. If you don't have a GPS with you there are numerous signs along the roads that will guide you there. The roads are typical Puerto Rican city roads that are tight and winding so stay on your... More

1. to get into the gift shop you had to step up a step so high that it had yellow caution tape around it. When you left the gift shop they have sharp warning signs be careful about the step down. It was not under construction. This appeared permanent 2. The entrance to the auditorium was not clearly marked. 3.... More

It's a bit of a drive to get to the observatory. The road to get there is narrow and has blind curves. So a little scary but fun. The attraction requires walking up a steep hill to get there. The tour is pretty interesting. But the coolest thing is seeing how darn big this thing is. If you go plan... More

Drove with my pal from San Juan to Arecibo...the drive through the tortuous roads was totally worth it!...got to touch some "space rocks" and feel super small next to the radio telescope.

Worlds largest radiotelescope with a dish about 1000 feet across! When you see it, you'll realize you've seen this place in several movies (Contact, Golden Eye...) but you just cannot believe how cool this place is. Great little "museum" to walk through while waiting for a tour--tours in English and Spanish. Short video followed by visit to the viewing deck... More

For me, it all began many years ago when the film 'Contact' came out. I was mesmerized by that gigantic radio telescope and the possibility of finding a way to make contact with other worlds. Yup, what a nerd. But when you finally get the chance to see it in person, you STILL find yourself mesmerized and in so many... More

We visited the Observatory last Wednesday, two adults and two teen boys. We arrived later than we wanted to as our visit to Camuy Cave took longer than expected. We were there at 4:00 and were able to catch the last movie and tour. Very informative movie. When you step out the door to see it you realize how large... More

I was very excited to see the Observatory, but I wasn't entirely sure what to expect. It was so neat. The information area in the building was comprehensive and although it was a hike from the parking lot, the "space walk" made it interesting along the way. The drive is worth it for those interested, but not sure kids will... More

It was a family trip to the Observatory. The group included two seniors, four kids and five adults. First time for everyone. It was a great experience for all of us. You have to make a short but steep walk but in case taht you can not do the walk they have a shuttle service. It's a self guided tour... More
