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

The Arecibo Observatory is a wonderful place to learn more about radio telescopes and the history of space observation in PR. The staff is extremely knowledgeable and responsive. The introductory movie is well made and the guided tour (while short) is insightful. The walk (again not very long) from the car to the observatory is steep but there are places... More

Whether it be because you are interested in space, radio transmissions into space, visiting places that you will only get to see once in a lifetime, or simply seeing places you have noted in movies (Golden Eye 007, Contact, The X-Files), you have to go here. The drive there takes you through the center of Puerto Rico through lovely areas.... More

Took the roads from the south of the island through the mountains of PR. It was tight roads but the vegetation was beautiful. Almost got lost because wireless reception is very poor and my GPS shut down. Stopped at a couple of places for directions and people were very nice. It is quite a walk from the parking lot to...

I enjoyed the actual observatory, but we drove two hours to get there, and our stay at the observatory lasted maybe 90 minutes, then we had a two hour drive back, so the long drive took away from the whole experience, not to mention that once you leave the main highway #22, the remaining 16-20 miles of road is narrow...

Worth the drive if you're into astronomy. Off the beaten path, so get good directions if you will be driving yourself. Located in a beautiful part of the island.
