As long as you have interest in science and seeing something special this is for you. We had a great time. About 60 miles from San Juan. They have a hands on visitors center, and a short movie about the facility. At the end you go outside to an overlook of the telescope. Is it huge. To think you are... More

Once can not imagine just how big this antenna is until you standing at the top of it....the gift shop was nice and interactive for all ages....the antenna looks old because it is and it still works...make sure to watch the films on how they make repairs on the antenna...it's interesting.

I'm not too into science, but I had a blast at the Observatory! The drive up there was very scenic route, but also windy and hilly. The museum was fairly interactive and had a ton of information. There is a movie that you view before getting to look at the telescope and it sets you up for the big show.... More

This place is a little out of the way, but the drive itself can be very interesting. Once you arrive, you will find that there can be limited parking. You'll also find a pretty steep walk up to the observatory. $10 entrance fee is a little much considering the brevity of the exhibit. The telescope itself is pretty amazing to... More

I've always wanted to visit the Arecibo Obsevatory. I'm so glad I finally did. Great drive through Arecibo. Only $10 entrance fee. Very informative and educational. Amazing views. The exhibits are interactive and great for kids.

The Arecibo Telescope is pretty amazing. The surrounding Karst topography is dramatic and well worth a trip to see by itself. There is a small attached museum with some nice meteorites. All in all, well worth a visit especially if you are a science geek like me. It is a bit expensive, though, with a $10 charge per adult.

As somewhat of a science geek (not quite, but close), architectural fan, Bond fan (kind of), and avid photographer, I just had to stop by this place as it combined all of these things into one. It met my expectations - and got me my daily climbing workout! Enjoyed the visit - I was there mostly for the visual aspect... More

Parking is at the bottom of the hill, with a steep walk up, but be sure to check out the scale model of the solar system. Starts at the pavilion at the bottom with the Sun, followed by Mercury, Venus, Earth, etc. as you go up. Gives a good excuse to stop and rest for those who find the hill... More

Very interesting to see the largest telescope-- but incredibly difficult to get to-- our driver got lost and then there is a very steep walk up to the observatory. Short film and interesting exhibits-- would have been interesting for our children to see -- but not worth going back for second visit.

Great history, great staff, and a wonderful learning experience. Must see for history lovers and people who are interested in astronomy, space, etc. We enjoyed this as part of our vacation in Puerto Rico and would definitely return!
