It's more impressive in person! That's all I can say! It's also in the mountains so on your way there you will get a nice view of Puerto Ricos natural resources!

The BF was may more into the science behind it than I was. I thought the drive up the mountain was the best part of the whole dang thing! We had a blast, winding curves, speeding natives, steep drop offs.. laughed the whole way.

This place was horrible. I was willing to look past the lack of interesting things inside the observatory and the robotic employees until I realized my card information was stolen after I used it in the gift shop here. Even though it was the most boring thing that I did while in Puerto Rico, I decided to spend around $80.00... More

First of all for people that are not familiar with this it is not just an Observatory which I thought but it is the largest dish in the world that is built into a mountain in the Arecibo, Puerto Rico area. This came about I think in the 60s by some scientists It sends and receives radio waves and to... More

Don't get me wrong from the title. It is an awesome observatory and very fascinating to see. But there's not a lot there. A long drive, a climb up a hill, look down at the dish, look up at the towers and you're done. I'm glad I saw it, but it took a long time for not a lot

It is a fun science center for children and adults. Some material may be outdated but helpful. We were where James Bond film was taped years ago. The observatory is spectacular. A must see if on the island. It takes time to get there, but loads of fun.

I think the best part about visiting the Observatory is that you can say you were there. We are not into that kind of exploration and were a bit bored looking at pictures and reading about the site. I hosted a young couple this year that could not wait to get there and experience the amazing display that it is.... More

For me, the best attraction in Puerto Rico, but being in the sciences, I am biased. However, this is impressive to anyone and even more impressive if you are a James Bond fan. Beside the telescope, the museum has fascinating displays and exhibits to interest young and old. This was so impressive to me I even bought an expensive tee... More
