This is something you can't see anywhere else! My family and I really enjoyed the whole experience! We didn't have any trouble finding it...signs along the way and attached to utility poles helped us know we were on the right path. The visitors center had great interstices exhibits, the intro movie and presentation were well done and informative and the... More

The Arecibo Radio Observatory is great!!! It's hard to find. The roads are not well marked or signed. No reception from AT&T or T-Mobile, so using our phones as GPS was useless. Only found one guy along the route who spoke fluent English, thanks to him (and luck) we got there!!! Thanks Dennis!! Once there, you must put your phones... More

Amazing for any science buff. The road there is tricky, curvy, and narrow. The visitors center is very hands on. The guides know a lot and can answer any questions. We spent a long time just staring at the actual radio telescope.

We almost missed out on this incredible experience due to heavy rain and a suicidal GPS. Once we got there, we were given a lift to the observatory (the walk would have been quite enjoyable had it not been pouring) and explored the exhibits and watched a fascinating documentary on the making of the telescope. The feature, however, does not... More

This was one of our best outings in Puerto Rico and there were many. I was fascinated by the karst landscape which provided the large sinkhole to house the circular reflector. The visitor center could not be more interesting. Lots or science and public information. This is a very worthwhile activity for young and old. We only spent have a... More

The road to the observatory is scary. We called ahead because people had told us there was a walk up the mountain after the parking lot. That's true but If you ask the guard they will send a van to get you. There are ramps and elevators to get around. My mom got to see everything. They have a 17... More

I visited this place a long time ago and it wasn't what I expected, maybe with the years it has improved. I will visit again soon.

Kids will like all the interactive exhibits in the visitors centers. Adults will love the sheer awesomeness of this telescope and hopefully appreciate its contributions to science. You have to take some back roads that twist and wind up hills to get here, but I was so glad I went. If you happen to be a big Bond fan, then... More

Arecibo was such an amazing experience to visit. I love Astronomy so it was unbelievable that I got to visit the world's largest radio telescope. The interactive museum part in the observatory was fun. Admission tickets were fairly cheap. BUT THE BEST PART OF THE TRIP WAS THE "VIP TOUR"!!!! An employee near the admission sales office was going to... More
