Visited the observatory on a Sunday morning first thing - definitely would recommend this as we were 2 of 3 people with lots of room to navigate all the displays. It isn't a huge visitors centre do if it was busy it might not be that enjoyable. The movie about the observatory is about 15 minutes and very good. Outside,... More

It is great to see and good for a walk around. Not something you do twice... The museum was of a good quality for something set in the jungle on an island

What looks like a ride through farmland and residential roads for a few miles leads you to one of the great man made creations and a great education. Plan to spend about one to two hours here and yes, call ahead if you need special needs as there are many steps up to the observatory. There is a tour and... More

This telescope is in a few movies and you don't understand it's massive size until you are standing at its edge. The short movie in the auditorium sums up history and how it works great, so even if you are not a telescope, universe or astrology geek this is still neat. It is a pretty steep climb from the parking... More

This is one of those attractions that are iconic. I've seen and heard of it most of my life. It was crazy to see the size and immensity of the dish and its parts. The museum was good and had interesting info. The drive up to the observatory helped to make it memorable, it was very Puerto Rico. The roads... More

A little hard to find, hidden in the Karst region of Eastern PR, the observatory is actually pretty amazing when you get there. The visitor center was a little run down, but the enormity of the dish itself is amazing to see.

When visiting Puerto Rico, I would highly recommend visiting the Observatory! It is about an hour and a half from San Juan. We rented a car and it was a very easy and beautiful drive. You should definitely watch the informative video before heading out to see the telescope...it's offered in both English and Spanish. There is also a small... More

This is the largest radiotelescope in the world! It's located in the municipality of Arecibo, surrounded by nature and humble people, is the best spot the astronomical community can ask for. NASA, the NSF, many universities and other entities use it to discover and monitor some of the key universe findings of our era. This place should be a UNESCO... More

If you like science and the space, this is a not to miss place. You can see the observatory, in the middle of a rain forest as well as some exhibitions on our solar system and the space. It is an amazing experience for a traveler to Puerto Rico. I greatly encourage it. In fact going to Arecibo was one... More
