Arecibo Observatory Reviews & Ratings

  • It is a beautiful walk up to the observatory. The staff is amazingly knowledgeable and friendly. There is an admission cost of $13.00 for adults. Included in this price is a guided tour of the facility as well as a short film explaining a brief history of the observatory. The museum has several interactive "games" to help explain the science, technology, and physics of the radio telescope. There is a small food area for you to refuel before making the 500 steps or more back to your vehicle.

  • Very cool place! Don't skip the video that explains how it came to be. The drive there is mountainous & beautiful. It's quite a walk up from the parking lot to the entrance - up several steps & then a paved incline. They have a little cafe with snacks and drinks on the observation deck.

  • Great history of space and atmosphere observation. VIP tour was great but active experiments prevented us for going closer to the dish. Recommend the crazy winding roads to get there!

  • Definitely worth the trip! Free parking. Security at bottom of the stairs is there if you require additional assistance with the trip up to the observatory, just ask they will provide shuttle service from bottom parking lot. The admission was under $10. They have vip tours for $15 extra, that takes you down to the edge of the dish. Very informative movie presentation, personal guided tour, guides are bilingual. Mine was working on her third language (French). Very good experience. A must go! Check hours before you go! 10a-3p.

  • LOVED the Observatory!! So cool!There were lots of schoolchildren there when we went during the weekday. But it was fine. they have a moon rock and a meteorite from Mars. It's well worth it to take the VIP tour and look behind the scenes. One of the best things we did in Puerto Rico.

  • What is the best way of getting to Arecibo from San Juan? Is Arecibo open on a Sunday?

    • Since there are no public modes of transportation available to reach Arecibo from San Juan, renting a car or hiring a taxi will be the best option to travel. Yes, the observatory remains open on Sundays.
