The Arecibo Observatory: The Truth Is Out There

arecibo observatory puerto ricoThe Arecibo Observatory is CURRENTLY home to the world’s largest single-aperture radio telescope with a diameter of 1000ft (305m). Unfortunately that crown will be handed over to China in 2016 when the radio telescope goes online in the Guizhou Province in southern China.

The Arecibo Radio Telescope is used to study three major research areas: radio astronomy, aeronomy, and radar astronomy and opened to researchers in 1963. Since its opening many scientific discoveries have been made at the observatory, as well as several blockbuster movie scenes.

When you arrive at the Observatory park your car in the car park and then take the path uphill (quite steep) to the visitor center. The walk is a combination of pavement and steps with a couple of places to take a break. The walk is not that long, but if you have trouble walking or need assistance, you can ask the guard in the car park and they will arrange transport to the visitor center.

This is a 2 floor room, that has exhibits about the solar system, the earth, as well as displays of meteor fragments. Some exhibits are just static displays, some have videos and some are interactive, where you have to read instructions and see what happens. The second flow has a few more exhibits and there is an elevator if you need one.

Just off the exhibit room there is the small theater where they show a 20 minute film highlighting what happens at the observatory.

After the movie (which is not mandatory) you head out to the observation deck to see the Arecibo radio telescope up close. It’s an impressive site.

After you have marveled at the huge radio telescope head on into the gift shop and take a momentum or two back with you.

arecibo observatory puerto ricoTip: I personally enjoyed the Arecibo Observatory, but it is not a place where you will spend several hours looking around and it is not for everyone (allow about 60-90 minutes). If you plan on visiting the observatory I would recommend that you combine the trip with another attraction in the area. Some suggestions:

  • Lago Dos Bocas – A great place to have lunch overlooking a lake (restaurants open on weekends and holidays)
  • Arecibo Lighthouse Park – small childrens park with ¾ scaled replica pirate ships. Also has great coast views and a lighthouse
  • Prime Outlets – The Barceloneta outlets mall is a great place to find bargains
  • Camuy Caves – If you decide to combine the caves with the Observatory, visit the caves first as tours are given on a first come first served basis. So it is recommended to arrive at the caves early.

Also, the interactive exhibits are good and very educational, but they are not geared towards younger children; although they will enjoy pressing the buttons and seeing things happen. It would be nice to see the Observatory introduce a children’s section that had more age appropriate displays

Directions from San Juan:
Take Route 22 west to Arecibo exit 77b. Then take Route 129 south and take the left exit when you see the large Arecibo Observatory sign. Continue on the smaller road following the Observatory signs. The road takes you through several neighborhoods so drive carefully as the road twists and turns. The Arecibo Observatory is at the end of Road 625. The drive is about 90mins (depending on traffic).

  1. Great experience. Fair price. I went with a 7 and a 4 year old. They have a nice time exploring the museum.
    The place is beutiful. You can heard a lot of birds and the mountains around and limestone of the “Mogotes” are impressive. The facility is out of this world. Only thing. I will give the visitors more information about the discoveries and the impotence of the research made at the Observatory. Finally, the store was very good with a lot of variety. It takes inside an hour or hour and a half.

    1. Rafael, Glad you had a good time at the Observatory. Agree that they could have more displays on what work they have done there and I also think they should have more hands on exhibits aimed at younger children

      Agree folks should look at spending about 1 to 1.5 hrs there

  2. Me, my husband, and my 3 children visited Puerto Rico last summer and we went to the observatory. We all enjoyed the ride there, especially my kids because they had never taken a road trip like that one. The scenery was so beautiful and peaceful. The displays inside the observatory were a little boring for the kids, but once we were able to go outside and see the actual telescope, they tought it was the “coolest” thing. Overall, we all enjoyed our visit to the Observatory, and to Puerto Rico. It’s such a beautiful island!
