What Travellers Say
Reviews Summary
Visitors acknowledge the tragic collapse of the iconic Arecibo telescope but still find value in seeing the remnants and learning about its scientific legacy. While access can be limited and the main attraction is gone, the historical significance and the passion of the staff are often highlighted as positive aspects.
"I had the privilege of visiting the center the day when they first reopened it to the public after the collapse, years ago. Regretfully, it looks like its closed again but the experience I did have was pleasant. Cool presentations, very knowledgeable and passionate staff.
Frankly, seeing that massive dish is staggering. Truly a tragic fate."

"It's still closed, but it's a cool stop for those who know its significance."
Chris Hoffman
"Really wished the museum/exhibits area was open. We came in with the hope to see some remains of the radio telescope. Like rightly pointed by many here, the observatory area is closed and the best you get is a picture of the remaining dish and two pillars from far far away. Unless you enjoy the ride to the observatory through winding small roads along the countryside, there is really nothing to see here right now."
